AWS CWI Part A WIT Chapter 5 Practice Test

This chapter-wise practice test focuses on:

Welding Inspection Technology Chapter 5—Documents Governing Welding Inspection and Qualification

Welding inspection is not based on personal opinion. An inspector must determine whether the work complies with the applicable contractual documents, drawings, codes, standards, specifications, approved welding procedures, qualification records, and acceptance criteria.

A weld that appears satisfactory may still be unacceptable when it does not meet the required dimensions, procedure variables, material requirements, or documentation provisions. Similarly, a visible discontinuity is not automatically rejectable unless it exceeds the acceptance criteria of the governing document.

The purpose of welding inspection is therefore to compare the actual work with the requirements established by the applicable documents and report the results accurately.

Important WIT Edition Note

This UpWeld page follows the chapter arrangement used in the AWS Welding Inspection Technology Fifth Edition, where the subject appears as Chapter 5.

In the Welding Inspection Technology Sixth Edition published in 2020, the addition of a separate cutting-process chapter changed the numbering. The same subject appears as:

Chapter 6—Documents Governing Welding Inspection and Qualification

The Sixth Edition organizes the chapter around welding-inspection documents, drawings, codes, standards, specifications, material control, and qualification of procedures and welders.

Candidates should confirm which WIT edition is being used by their training provider.

AWS B2.1 provides requirements for qualifying welding procedures, welders, and welding operators and recognizes that other referencing documents—such as codes, contracts, specifications, and quality manuals—may impose additional or controlling requirements.

Why Governing Documents Are Important

A welding inspector must know exactly which documents apply to the work.

Requirements may come from several sources, including:

• Purchase orders

• Contracts

• Project specifications

• Engineering drawings

• Applicable welding codes

• Material specifications

• Approved WPSs

• PQRs

• Welder qualification records

• Inspection and test plans

• Quality-control procedures

• NDE procedures

• Manufacturer instructions

• Regulatory requirements

These documents may establish requirements for materials, joint design, welding processes, preheat, filler metals, welder qualification, inspection methods, testing frequency, acceptance criteria, repairs, documentation, and final release.

The inspector should review the applicable documents before welding begins. Waiting until final inspection to discover an incorrect material, unqualified procedure, or improperly qualified welder can result in significant repair, delay, or rejection.

Document Hierarchy and Order of Precedence

A project may contain several documents that address the same subject. Occasionally, two requirements may appear to conflict.

There is no single order of precedence that automatically applies to every project. The controlling order must be established by the contract, procurement documents, project specification, applicable regulation, or other authorized document.

A project may establish an order such as:

1. Applicable laws and regulations

2. Contract requirements

3. Project specifications

4. Engineering drawings

5. Referenced codes and standards

6. Approved procedures

7. Manufacturer recommendations

However, inspectors must not assume that this example applies universally.

When requirements conflict or appear unclear, the inspector should:

• Identify the conflicting provisions

• Record the applicable document numbers and revisions

• Avoid making an unauthorized design decision

• Refer the matter to the responsible engineer, owner, contractor, or designated authority

• Obtain documented clarification

• Retain the clarification with the inspection records

The inspector’s role is to apply the established requirements—not to rewrite the contract or redesign the joint.

Drawings

Engineering and fabrication drawings communicate essential information about the component being manufactured.

A drawing may provide:

• Component dimensions

• Material identification

• Joint locations

• Joint configurations

• Welding symbols

• Weld sizes

• Groove details

• Weld lengths

• Field-weld requirements

• Weld-all-around requirements

• Surface-finish requirements

• NDE requirements

• Heat-treatment requirements

• General and specific notes

• Revision information

The inspector should confirm that the latest approved drawing revision is being used. An older drawing may contain dimensions, materials, weld symbols, or inspection requirements that have since been changed.

A drawing should be read as a complete document. Information may be located in the title block, revision block, general notes, detail views, section views, welding symbols, bill of materials, or referenced specifications.

Codes

A code is a systematic collection of requirements covering a particular subject or type of construction.

A welding code may address:

• Design requirements

• Base materials

• Welding consumables

• Joint details

• Welding-procedure qualification

• Welder qualification

• Fabrication requirements

• Inspection methods

• Nondestructive examination

• Acceptance criteria

• Repair requirements

• Documentation

A code may become legally enforceable when it is adopted by a governmental authority, incorporated into a regulation, or made mandatory by a contract.

AWS QC1 defines a code as a standard containing conditions and requirements for a particular subject, together with procedures for determining whether those requirements have been met.

Standards

A standard provides established rules, requirements, guidelines, methods, or characteristics for repeated use.

Standards may cover subjects such as:

• Welding terminology

• Welding symbols

• Filler-metal classification

• Welding-procedure qualification

• Welder qualification

• Mechanical testing

• Nondestructive examination

• Inspection-personnel qualification

• Safety practices

Under AWS terminology, the broad term standard may include codes, specifications, methods, recommended practices, and guides. A standard becomes mandatory when it is invoked by a contract, code, law, regulation, purchase order, or another controlling document.

Specifications

A specification describes essential technical requirements for a material, product, system, process, or service.

Specifications may establish:

• Chemical composition

• Mechanical properties

• Dimensions and tolerances

• Manufacturing methods

• Heat-treatment requirements

• Testing requirements

• Inspection requirements

• Marking and identification

• Certification requirements

• Acceptance criteria

AWS QC1 describes a specification as a standard detailing essential technical requirements and the procedures, methods, qualifications, or equipment necessary to verify compliance. A specification becomes mandatory when invoked by a controlling document or agreed upon by the contracting parties.

Codes, Standards, and Specifications: Key Difference

Candidates should understand the practical difference among these documents:

Code

A code normally provides a broad set of requirements for a particular type of construction, product, or service.

Standard

A standard is a recognized document containing rules, guidelines, test methods, terminology, or technical requirements.

Specification

A specification normally provides detailed technical requirements for a particular material, process, product, or service.

The exact use of these terms can vary between organizations. The inspector should read the scope and application provisions of the actual document rather than relying only on its title.

Applicable Edition and Revision

Codes and standards are periodically revised.

A newer edition is not automatically applicable to work already governed by an earlier edition. The applicable edition may be established by:

• Contract date

• Purchase order

• Project specification

• Regulatory adoption

• Drawing note

• Client instruction

• Code-of-record requirements

The inspector should verify:

• Document title

• Document number

• Edition year

• Addenda

• Amendments

• Errata

• Project modifications

• Approved interpretations

Using requirements from the wrong edition can lead to incorrect decisions.

The current AWS CWI program page lists QC1:2016-AMD1 for AWS certification and B5.1:2025 for qualification of welding inspectors, illustrating why candidates and working inspectors should confirm current document editions.

Mandatory and Advisory Language

Words used in governing documents can significantly affect the meaning of a requirement.

Shall

Shall normally identifies a mandatory requirement.

Should

Should normally identifies a recommended practice or guideline.

May

May normally indicates permission, an option, or an obligation to make a permitted choice, depending on the document’s defined usage.

Can

Can generally describes capability or possibility rather than a mandatory requirement.

AWS QC1 specifically states that shall denotes a requirement, should denotes a guideline, and may denotes an obligation to make a choice.

Candidates should always check the definitions or verb-usage section of the governing document.

Acceptance Criteria

Acceptance criteria establish the allowable type, size, location, number, or distribution of discontinuities and dimensional variations.

Acceptance criteria may address:

• Cracks

• Porosity

• Slag inclusions

• Incomplete fusion

• Incomplete joint penetration

• Undercut

• Overlap

• Weld size

• Weld profile

• Reinforcement

• Misalignment

• Surface finish

• Dimensional tolerances

A discontinuity is not automatically a defect.

A discontinuity is an interruption in the normal structure or configuration of a material or weld. It becomes a defect when it exceeds the applicable acceptance criteria and is therefore rejectable.

The welding inspector should never reject or accept a condition solely because it “looks bad” or “looks acceptable.” The decision must be based on the governing criteria.

Control of Materials

Material control helps ensure that the correct base materials and welding consumables are used.

The inspector may be required to verify:

• Material specification

• Grade or type

• Heat number

• Lot number

• Dimensions

• Condition

• Identification markings

• Material certificates

• Traceability

• Storage conditions

• Approved substitutions

• Transfer of identification after cutting

• Segregation of different materials

Loss of material identity can create a serious quality problem because the material’s specification, grade, heat treatment, or mechanical properties may no longer be verifiable.

The Sixth Edition WIT chapter specifically places material control alongside drawings, codes, standards, specifications, and qualification requirements.

Material Test Reports

A Material Test Report may also be called a:

• Mill Test Report

• Mill Test Certificate

• Material Certificate

• Certified Material Test Report

Depending on the material and governing specification, the report may include:

• Manufacturer’s name

• Material specification

• Grade

• Heat number

• Product dimensions

• Chemical composition

• Tensile strength

• Yield strength

• Elongation

• Impact-test results

• Heat-treatment condition

• Test methods

• Certification statement

The inspector should compare the report with the purchase order, material markings, drawing requirements, and applicable material specification.

A certificate should not be accepted merely because one is available. The information must correspond to the actual material and required specification.

Filler-Metal and Consumable Control

Welding consumables must comply with the applicable WPS and governing documents.

The inspector may check:

• Electrode or filler-metal classification

• Manufacturer

• Trade designation

• Diameter

• Lot or batch number

• Storage temperature

• Exposure time

• Reconditioning requirements

• Shielding-gas composition

• Flux condition

• Consumable cleanliness

• Issue and return records

Low-hydrogen electrodes, fluxes, and other moisture-sensitive consumables may require controlled storage and exposure limits.

Incorrect consumables can affect:

• Weld-metal strength

• Toughness

• Chemical composition

• Corrosion resistance

• Hydrogen level

• Arc characteristics

• Usability

• Final weld quality

The exact storage and handling requirements must be obtained from the applicable code, WPS, project specification, and manufacturer’s instructions.

Welding Procedure Specification

A Welding Procedure Specification, commonly abbreviated as WPS, is a written document that provides direction for making production welds.

A WPS may include:

• Welding process

• Joint design

• Base-metal specification or grouping

• Thickness range

• Filler-metal classification

• Electrode diameter

• Current type

• Polarity

• Amperage

• Voltage

• Travel speed

• Welding position

• Progression

• Preheat temperature

• Interpass temperature

• Shielding gas

• Gas-flow rate

• Backing

• Purging

• Postweld heat treatment

• Welding technique

The WPS should contain enough information for a properly trained welder or welding operator to produce the required weld consistently.

AWS describes WPSs as documents that direct welders in consistently producing welds that meet the required conditions. AWS training also distinguishes the WPS from its supporting PQR.

Procedure Qualification Record

A Procedure Qualification Record, abbreviated as PQR, records the actual variables used to produce a procedure-qualification test weld and the results of the required examinations and tests.

A PQR may include:

• Actual base metal

• Actual thickness

• Joint configuration

• Welding process

• Actual filler metal

• Electrode diameter

• Current and polarity

• Amperage

• Voltage

• Travel speed

• Heat input

• Preheat

• Interpass temperature

• Shielding gas

• Postweld heat treatment

• Visual-examination results

• NDE results

• Tensile-test results

• Bend-test results

• Impact-test results

• Other required test results

The PQR is a record of what actually occurred during qualification. The WPS uses the qualified results to establish the permitted production-welding ranges.

AWS B2.1 includes procedure qualification, performance qualification, qualification variables, testing requirements, example WPS forms, example PQR forms, and performance-qualification records.

Difference Between a WPS and a PQR

Candidates should clearly understand the distinction.

WPS

The WPS tells the welder or welding operator how production welding is to be performed.

PQR

The PQR records how the qualification coupon was actually welded and how it performed during testing.

The WPS provides instructions and permitted ranges. The PQR provides supporting evidence for those ranges when procedure qualification by testing is required.

A WPS should not be treated as a record of actual production variables, and a PQR should not be used as a substitute for production-welding instructions.

Types of Welding Procedure Specifications

Depending on the governing document, a WPS may be established through different methods.

WPS Qualified by Testing

A test coupon is welded using selected variables. The coupon is examined and tested, and the actual variables and results are documented on a PQR.

When the qualification meets the governing requirements, a WPS can be prepared within the qualified ranges.

Prequalified WPS

Some construction codes permit certain welding procedures to be used without separate procedure-qualification testing when all prequalification requirements are satisfied.

Prequalification may depend on:

• Approved welding process

• Listed base metal

• Approved filler metal

• Joint detail

• Thickness

• Welding position

• Preheat

• Technique

• Other code limitations

A procedure is not prequalified merely because it has been successfully used before.

Standard Welding Procedure Specification

AWS publishes Standard Welding Procedure Specifications, commonly called SWPSs, for certain commonly welded material, process, and filler-metal combinations.

An SWPS must be supported by qualification records and may be used only when accepted by the governing or referencing document and when all applicable adoption requirements are satisfied.

Welding Procedure Variables

Qualification documents identify variables that can affect the validity or range of a welding procedure.

The exact categories and rules depend on the governing code.

Essential Variables

An essential variable is a variable whose change beyond the permitted range generally requires requalification of the welding procedure.

Examples may include changes involving:

• Welding process

• Base-metal grouping

• Filler-metal grouping

• Thickness range

• Welding position

• Shielding gas

• Heat treatment

• Electrical characteristics

The actual list must be obtained from the applicable qualification standard.

Nonessential Variables

A nonessential variable may be changed within the rules of the governing document without repeating procedure-qualification testing.

However, the WPS should still be revised so that it accurately reflects the instructions given to production personnel.

Supplementary Essential Variables

Some codes apply supplementary essential variables when impact toughness or similar notch-toughness requirements are imposed.

A variable that is nonessential for one application may become supplementary essential when toughness qualification is required.

Candidates should never assume that the variable categories are identical in every code.

Procedure-Qualification Process

A typical procedure-qualification process includes:

1. Reviewing the governing qualification requirements

2. Preparing a preliminary welding procedure

3. Selecting the test-coupon material and dimensions

4. Confirming material traceability

5. Assigning a qualified person to weld the coupon

6. Recording the actual welding variables

7. Performing required visual examination

8. Performing required nondestructive examination

9. Removing mechanical-test specimens

10. Conducting the required destructive tests

11. Recording all test results

12. Preparing and certifying the PQR

13. Developing the final WPS within qualified limits

14. Approving the WPS for production use

The tests may include tensile, bend, impact, macroetch, hardness, fracture, or other examinations, depending on the governing document.

AWS B2.1 separates procedure qualification from welder and welding-operator performance qualification and establishes requirements for both.

Welder Performance Qualification

Welder performance qualification demonstrates a person’s ability to produce welds that meet prescribed requirements.

A welder qualification test may involve variables such as:

• Welding process

• Test-coupon type

• Base-metal thickness

• Pipe diameter

• Welding position

• Joint type

• Backing

• Filler metal

• Electrode form

• Welding progression

• Metal-transfer mode

After welding, the test coupon may be evaluated by:

• Visual inspection

• Bend testing

• Radiographic examination

• Fracture testing

• Macroetch testing

• Other required methods

Welder performance qualification demonstrates the individual’s ability. It does not qualify the welding procedure itself.

AWS describes welder performance qualification as the demonstration of a welder’s ability to produce welds meeting prescribed standards. The written qualification record documents the applicable variables and test results.

Welding-Operator Qualification

A welder manually manipulates the electrode holder, torch, or welding gun.

A welding operator operates adaptive-control, automatic, mechanized, or robotic welding equipment.

Because the person’s control of the operation differs, welding-operator qualification requirements may differ from manual welder qualification.

The inspector should verify whether the person performing the work is classified as:

• Welder

• Welding operator

• Tack welder

• Brazer

• Brazing operator

The correct qualification provisions must be applied to the work actually being performed.

Welder Qualification Test Record

The document recording welder or welding-operator qualification may be called:

• Welder Performance Qualification Record

• Welder Qualification Test Record

• Welding Performance Qualification Record

• WPQR

• WQTR

• Performance Qualification Test Record

The terminology depends on the governing code.

The record may contain:

• Person’s identification

• Test date

• Welding process

• WPS used

• Base material

• Thickness or diameter

• Filler metal

• Welding position

• Backing

• Progression

• Actual qualification variables

• Test methods

• Test results

• Qualified ranges

• Certification or authorization signatures

AWS provides official sample forms for WPSs, PQRs, and welder or welding-operator qualification records for several welding codes and specifications.

Procedure Qualification and Welder Qualification Are Different

This is one of the most important Chapter 5 concepts.

Procedure Qualification

Procedure qualification demonstrates that a selected combination of materials, welding variables, and techniques can produce a weld with the required properties.

Welder Qualification

Welder qualification demonstrates that an individual can use a welding process and procedure to produce an acceptable weld.

Therefore:

• A qualified WPS does not automatically qualify a welder.

• A qualified welder does not automatically qualify a WPS.

• Production welding generally requires both an acceptable procedure and properly qualified personnel.

Qualification Range

A qualification test may qualify more than the exact conditions used during testing.

Depending on the governing code, one test may establish permitted ranges for:

• Material thickness

• Pipe diameter

• Welding position

• Joint type

• Backing

• Filler metal

• Welding process

• Welding progression

The qualification range must be determined from the applicable code tables and rules.

A welding inspector should not guess the range or assume that a difficult test position automatically qualifies every possible production condition.

Continuity and Validity of Qualification

Many welding codes include provisions for maintaining welder or welding-operator qualification through continuity of process use.

Qualification may be affected when:

• The individual does not use the process within the permitted period

• There is a specific reason to question the person’s ability

• An essential performance variable changes

• The governing document requires requalification

• Qualification documentation cannot be verified

The exact continuity period, required records, and requalification rules are code-specific.

The inspector should verify current continuity records rather than relying only on the original qualification-test date.

Qualification and Certification

The terms qualification and certification are related but are not identical.

Qualification

Qualification is the demonstrated training, knowledge, skill, and experience required to perform specified work.

Certification

Certification is written verification that a person has satisfied the requirements of a defined certification program.

AWS B5.1 establishes qualification requirements for welding inspectors, while AWS QC1 establishes the AWS certification program. Meeting B5.1 requirements alone does not permit a person to claim the AWS CWI title; AWS certification must be obtained and maintained under QC1.

Welding Inspector Responsibilities

The welding inspector may be required to review documentation before, during, and after welding.

Before Welding

The inspector should verify:

• Applicable contract documents

• Correct drawing revision

• Applicable code edition

• Material specifications

• Material identification

• Approved WPS

• Supporting PQR where required

• Welder or operator qualification

• Qualification ranges

• Consumable classifications

• Inspection and test plan

• Required hold or witness points

• NDE procedures

• Measuring-equipment calibration

During Welding

The inspector may verify:

• Correct WPS is available

• Correct process is being used

• Welder identification

• Joint preparation

• Fit-up

• Base material

• Filler metal

• Preheat

• Interpass temperature

• Current and polarity

• Amperage and voltage

• Shielding gas

• Travel speed

• Welding position

• Cleaning between passes

• Required inspection stages

After Welding

The inspector may verify:

• Completed weld dimensions

• Visual acceptance

• Required NDE

• Heat-treatment records

• Repair documentation

• Welder traceability

• Final inspection reports

• Material records

• Qualification records

• Release documentation

AWS QC1 requires CWIs and SCWIs to verify that inspected work and maintained records conform to applicable standards. It also assigns the employer responsibility for determining whether certified personnel are capable of performing a particular inspection assignment.

Common Documentation Problems

The inspector should remain alert for problems such as:

1. Obsolete drawing revisions

2. Incorrect code editions

3. Missing project specifications

4. Unapproved material substitutions

5. Missing heat-number traceability

6. Incomplete material certificates

7. WPS values outside PQR support

8. WPS not approved for production

9. Welder qualified for the wrong process

10. Expired or unsupported continuity

11. Qualification outside the permitted position or thickness range

12. Incorrect filler-metal classification

13. Missing preheat or PWHT records

14. Unsigned qualification records

15. Missing test results

16. Illegible document revisions

17. Conflicting requirements without documented clarification

18. NDE reports referring to the wrong weld number

19. Incomplete repair records

20. Uncontrolled handwritten changes

Accurate document control is essential because an inspection decision must be traceable to the applicable requirement and objective evidence.

How to Review a WPS

A systematic WPS review should include the following steps:

Step 1: Identify the governing code

Determine which code or specification controls procedure qualification.

Step 2: Confirm WPS identification

Check the WPS number, revision, date, approval, and status.

Step 3: Confirm supporting qualification

Determine whether the WPS is prequalified, supported by a PQR, or adopted as an accepted SWPS.

Step 4: Verify welding process

Confirm that the specified process matches the production operation.

Step 5: Review materials

Check base-metal grouping, filler-metal classification, and qualified thickness ranges.

Step 6: Review joint details

Confirm groove type, root opening, root face, backing, and joint configuration.

Step 7: Review electrical variables

Check current type, polarity, amperage, voltage, and transfer mode where applicable.

Step 8: Review thermal requirements

Check preheat, interpass temperature, heat input, and PWHT requirements.

Step 9: Review shielding and technique

Verify shielding gas, flow rate, purging, progression, electrode extension, and other technique variables.

Step 10: Compare with production

Confirm that actual production conditions remain within the WPS requirements.

How to Review a Welder Qualification Record

When reviewing a welder or operator qualification record, check:

• Individual’s correct name or identification

• Test date

• Welding process

• WPS used for the test

• Test-coupon material

• Thickness or diameter

• Welding position

• Joint type

• Backing condition

• Filler-metal variables

• Welding progression

• Test method

• Test results

• Qualified range

• Required signatures

• Continuity status

A welder may be highly experienced and still lack the qualification required for a particular project condition. Qualification must be demonstrated through the applicable record.
