AWS AWS Welder Qualification & Procedure Testing 2 — Questions and Answers
Question 1: What test specimens are typically required for groove weld procedure qualification under AWS D1.1?
- Hardness tests only
- Bend tests and tensile tests (Correct answer)
- Impact tests and chemical analysis
- Visual inspection only
Correct answer: Bend tests and tensile tests
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?
- Tensile strength
- Weld ductility and fusion across the cross-section (Correct answer)
- Hardness
- Impact resistance
Correct answer: Weld ductility and fusion across the cross-section
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:
- Only appearance inspection
- Requalification of the procedure (Correct answer)
- Inspector approval only
- Changing the electrode brand
Correct answer: Requalification of the procedure
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:
- A groove weld test plate
- A fillet weld break test and macroetch examination (Correct answer)
- An impact test specimen
- A hardness traverse only
Correct answer: A fillet weld break test and macroetch examination
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:
- Measure tensile strength
- Visually examine the weld cross-section for fusion, penetration, and discontinuities (Correct answer)
- Check weld bead color
- Confirm shielding gas purity
Correct answer: Visually examine the weld cross-section for fusion, penetration, and discontinuities
A macroetch examination involves etching and examining a weld cross-section to reveal fusion, penetration depth, bead profiles, and internal discontinuities.
Question 6: Under AWS D1.1, if a welder fails a qualification test, when may they retest?
- Never — they must wait 6 months
- Immediately after additional practice, upon immediate retest (Correct answer)
- Only after completing a formal retraining program
- After passing a written exam
Correct answer: Immediately after additional practice, upon immediate retest
AWS D1.1 allows immediate retesting after additional practice or preparation following a failed initial test.
