AWS AWS Welder Qualification & Procedure Testing 2

Question 1

What test specimens are typically required for groove weld procedure qualification under AWS D1.1?

Accepted Answer

Bend tests and tensile tests

Answer

AWS D1.1 procedure qualification for groove welds requires both bend tests (face, root, or side) and tensile tests to verify mechanical properties.

Question 2

What does a side bend test for groove weld procedure qualification evaluate?

Accepted Answer

Weld ductility and fusion across the cross-section

Answer

Side bend tests reveal lack of fusion, incomplete penetration, and evaluate ductility of the weld cross section.

Question 3

An 'essential variable' in a welding procedure is one whose change beyond code limits requires:

Accepted Answer

Requalification of the procedure

Answer

Essential variables are parameters that, when changed beyond allowed limits, affect weld mechanical properties and require the procedure to be requalified.

Question 4

When qualifying a WPS for fillet welds under AWS D1.1, the test uses:

Accepted Answer

A fillet weld break test and macroetch examination

Answer

Fillet weld procedure qualification uses the fillet weld break test and macroetch to verify size, fusion, and cross-sectional soundness.

Question 5

The purpose of a macro examination in weld procedure qualification is to:

Accepted Answer

Visually examine the weld cross-section for fusion, penetration, and discontinuities

Answer

A macroetch examination involves etching and examining a weld cross-section to reveal fusion, penetration depth, bead profiles, and internal discontinuities.
