Detail Description
Paper Name CSWIP 3.1 – Paper Two (Technology / WPS & Codes)
Number of Questions 30 (approx)
Passing Score 70%
Time Allotted Usually 1 hour 30 minutes (subject to exam rules)
Key Topics WPS / PQR / WPQ, welder certification, code application (e.g. ASME, AWS, ISO), welding procedure review, acceptance criteria, welding QA/QC

How to Use This Practice Test?

  • Try to answer each question without looking at the answer first.
  • After selecting, read the explanation to understand the rationale.
  • Mark the questions you got wrong and revisit those topics.
  • Use this as a supplement to standards documents (ASME, AWS, ISO) and the official CSWIP exam syllabus.

Sample 30 MCQs for Paper Two with Answers & Explanations

Below are sample questions (with explanations). You can expand or replace as per your reference materials.

Section A: WPS / PQR / WPQ & Welder Qualification

Q1. In a WPS, the term “preheat” refers to:
a) Temperature applied before welding begins
b) Temperature applied after welding
c) Temperature measured during welding
d) Maximum allowed interpass temperature
Answer: a) Temperature applied before welding begins
Explanation: Preheat is the minimum base material temperature maintained before welding to reduce the cooling rate and hydrogen risk.

Q2. A PQR (Procedure Qualification Record) is used to:
a) Define allowable ranges in a WPS
b) Replace the WPS entirely
c) Certify the welder
d) Specify the acceptance criteria for defects
Answer: a) Define allowable ranges in a WPS
Explanation: The PQR documents the actual welding on test coupons, which the WPS then establishes ranges of parameters based on.

Q3. Welder qualification tests are typically valid for:
a) 6 months
b) 1 year
c) Unlimited duration
d) As long as the welding process remains unchanged
Answer: d) As long as the welding process remains unchanged
Explanation: Provided process, position, base material, and essential variables remain within the qualified ranges, the qualification remains valid.

Q4. In a WPS, “essential variables” are:
a) Variables that, if changed, invalidate the qualification
b) Variables you may change without requalification
c) Variables related to cosmetic appearance
d) Variables that are not recorded
Answer: a) Variables that, if changed, invalidate the qualification
Explanation: Essential variables must remain within qualified limits; any changes require requalification.

Section B: Welding Codes, Acceptance Criteria & Standards

Q5. According to AWS D1.1, the maximum allowable length of a staggered crack in a weld is:
a) 5 mm
b) 10 mm
c) 15 mm
d) 20 mm
Answer: b) 10 mm
Explanation: (Example value – verify for your code) Under AWS criteria, certain defects beyond 10 mm must be repaired or rejected.

Q6. Which standard usually governs welding symbols in engineering drawings?
a) ISO 2553
b) ASME IX
c) AWS D1.1
d) ISO 9001
Answer: a) ISO 2553
Explanation: ISO 2553 standardizes the presentation of welding symbols on drawings.

Q7. When reviewing a WPS, a welding inspector must check:
a) Base metal specification
b) Filler metal and consumable type
c) Welding positions and preheat / postheat data
d) All of the above
Answer: d) All of the above
Explanation: A WPS must cover base materials, consumables, positions, temperatures and all essential variables.

Q8. What does “PWHT” stand for?
a) Pre-Weld Heat Treatment
b) Post-Weld Heat Treatment
c) Partial Weld Hardness Test
d) Primary Welding Hardness Technique
Answer: b) Post-Weld Heat Treatment
Explanation: PWHT is done after welding to relieve residual stresses and improve toughness.

Section C: Application / Scenario-based Questions

Q9. If a WPS specifies a maximum interpass temperature of 300 °C, but during welding the temperature reaches 350 °C, what should the welding inspector do?
a) Continue welding (within tolerance)
b) Stop, cool the weld, and re-weld within limits
c) Approve if the bead geometry is acceptable
d) Modify WPS on the fly
Answer: b) Stop, cool the weld, and re-weld within limits
Explanation: Violating the range of a WPS essential variable invalidates the procedure unless retested.

Q10. A drawing calls for a V-groove weld using weld class “B” per the contract. The WPS submitted shows a bevel angle that differs. What should the inspector do?
a) Accept it if penetration is visible
b) Reject it and ask for a WPS revision
c) Accept if internal NDT is passed
d) Approve if the weld passes visual inspection
Answer: b) Reject it and ask for WPS revision
Explanation: WPS must comply with the contract drawing and specifications. Deviations require formal approval.

Frequently Asked Questions (FAQ)

Q1. How many theory papers are there in CSWIP 3.1?
There are two theory papers: Paper One (General / Welding Theory) and Paper Two (WPS, Codes & Application). 

Q2. What is the passing score for each CSWIP 3.1 paper?
The passing mark is typically 70% in each paper. (YouTube)

Q3. Which topics are emphasized in Paper Two?
Major topics include: WPS/PQR/WPQ, essential variables, code compliance (AWS, ISO, ASME), welder qualification, PWHT, review of welding procedures, contract compliance, and acceptance criteria.

Q4. Can a welder qualification under Paper One be used in Paper Two?
Not exactly. Paper Two often covers procedural and standards application. The tests are separate, though the knowledge overlaps.
