What Is Covered in API 1104 Section 4?

API 1104 Section 4 covers specification requirements related to welding equipment and materials. It explains how welding equipment should be operated, what material specifications are acceptable, how filler metals and fluxes are grouped, and how shielding gases must be handled.

This section is useful for understanding the basic requirements that support welding procedure qualification and production welding in API 1104.

Main Topics Covered in Section 4

4.1 Equipment

API 1104 requires welding equipment to be operated with good judgment, sound engineering practice, suitable operating practices, and attention to safety.

For arc welding, the equipment must be operated within the voltage and current ranges listed in the welding procedure specification. For gas welding, the equipment must be operated using the flame characteristics and tip sizes specified in the qualified WPS.

4.2 Materials

Section 4 also explains the requirements for pipe, fittings, filler metals, fluxes, and shielding gases.

Pipe and fittings must conform to API or applicable ASME, ASTM, MSS, or ANSI specifications. Materials may also be acceptable when they meet the required chemical and mechanical properties, even if they were not manufactured exactly according to the listed specification.

This means that the chemical and mechanical properties of the material are very important for API 1104 applications.

Filler Metals and Fluxes

API 1104 requires filler metals to conform to listed AWS filler metal specifications. Other filler metals may also be used if the applicable welding procedures are properly qualified.

API 1104 Table 1 divides filler metals, electrodes, and fluxes into different group numbers. These group numbers are based on electrode characteristics and the welding processes that use them.

Candidates should remember that API 1104 Group Numbers are different from AWS F-Numbers. For example, low-hydrogen SMAW electrodes may be AWS F-No. 4, but API 1104 classifies them as Group No. 3.

Filler Metal Grouping in API 1104

API 1104 groups filler metals and fluxes as follows:

• Group Nos. 1, 2, and 3 are used for SMAW
• Group No. 4 is used for SAW electrodes and fluxes
• Group No. 5 is used for GMAW, GTAW, and PAW electrodes
• Group No. 6 is used for the OFW
• Group Nos. 7, 8, and 9 are used for FCAW

Candidates should also pay close attention to the footnotes in Table 1 because they may modify the requirements for certain electrodes, filler metals, or fluxes.

Storage and Protection of Filler Metals

API 1104 requires filler metals and fluxes to be protected from deterioration and excessive changes in moisture. Damaged electrodes should not be used because they may not perform correctly during welding.

Low-hydrogen SMAW electrodes require special care because their coatings can absorb moisture from the atmosphere. Proper storage and handling help reduce the risk of hydrogen-related weld problems.

Although API 1104 may not give all detailed storage rules, good welding practice includes:

• Storing low-hydrogen electrodes in heated and vented ovens after opening sealed containers
• Limiting atmospheric exposure
• Following the recommended baking times and temperatures when required

Shielding Gases

API 1104 Section 4 also covers shielding gases used for welding. Shielding gases protect the weld pool from atmospheric contamination.

Inert gases do not chemically react with the weld pool. Common inert gases include argon and helium.

Active gases may interact with the arc, the weld pool, or both. Common active gases include carbon dioxide and oxygen.

For GMAW, mixtures of inert and active gases may also be used.

Shielding gases must be relatively pure and dry. The shielding gas or gas mixture used for welding must be qualified according to the applicable procedure qualification rules.

Storage and Handling of Welding Gases

Gases used for welding must be properly stored and handled. API 1104 states that gases shall not be field intermixed in their containers. Gases of questionable purity or gases from damaged containers shall not be used.

This requirement is important because poor-quality shielding gas can affect weld quality and may lead to welding defects.

What You Will Learn in This Quiz

This practice test will help you understand:

• Equipment requirements in API 1104 Section 4
• Use of voltage and current ranges in the WPS
• Gas welding flame characteristics and tip size requirements
• Acceptable specifications for pipe and fittings
• Filler metal and flux requirements
• Difference between API 1104 Group Numbers and AWS F-Numbers
• Storage and protection of filler metals and fluxes
• Requirements for low-hydrogen electrodes
• Shielding gas types and handling requirements
• Importance of dry and pure gases in welding

Why Practice Section 4 Specifications?

Section 4 is important for CWI Part C candidates because it provides the foundation for many welding procedures and production welding requirements. A welding inspector must understand how materials, filler metals, fluxes, and gases are controlled before welding begins.

In the AWS CWI Part C open-book exam, questions may test your ability to locate and apply these specification requirements correctly. Practicing this section helps improve your code navigation speed and exam confidence.
