AWS AWS Certification & Qualification

Question 1

What AWS document governs the qualification of welders and welding procedures for structural steel?

Accepted Answer

AWS D1.1 Structural Welding Code – Steel

Answer

AWS D1.1 (Structural Welding Code – Steel) contains requirements for welding procedure specifications (WPS) and welder qualification for structural applications.

Question 2

A Welding Procedure Specification (WPS) documents:

Accepted Answer

The specific variables and parameters to be used when making a production weld

Answer

A WPS is a written document that prescribes the welding variables (process, filler, preheat, position, etc.) required to produce a sound weld.

Question 3

What is a 'Procedure Qualification Record (PQR)'?

Accepted Answer

A record of the actual welding variables and test results used to support and qualify a WPS

Answer

A PQR documents the actual parameters used during a test weld and the mechanical test results that qualify the WPS.

Question 4

Under AWS D1.1, a welder's qualification test is considered to cover which type of position if the test is performed in the 3G position?

Accepted Answer

Flat, horizontal, and vertical

Answer

Under AWS D1.1, a 3G (vertical groove) qualification covers welding in flat, horizontal, and vertical positions.

Question 5

The term 'essential variable' in a welding procedure means:

Accepted Answer

A variable whose change requires re-qualification of the WPS by testing

Answer

Essential variables are those welding parameters whose change affects weld mechanical properties and thus requires requalification of the procedure.
