AWS AWS Welder Qualification & Procedure Testing 1 — Questions and Answers
Question 1: A Welder Performance Qualification (WPQ) test demonstrates that the welder:
- Understands all welding codes
- Can produce a sound weld following a qualified WPS (Correct answer)
- Has designed the welding procedure
- Can perform welding inspection
Correct answer: Can produce a sound weld following a qualified WPS
A WPQ test verifies the welder's ability to produce welds that meet code acceptance criteria when following a given procedure.
Question 2: What welding position is considered most difficult and generally qualifies a welder for all positions when passed?
- 1G (flat)
- 2G (horizontal)
- 6G (pipe inclined 45°) (Correct answer)
- 3G (vertical)
Correct answer: 6G (pipe inclined 45°)
The 6G position with pipe fixed at 45° is the most demanding; passing it qualifies the welder for all positions.
Question 3: A welder's AWS D1.1 qualification for a specific process may expire if the welder:
- Changes employers
- Has not used that process for more than 6 months (Correct answer)
- Transfers to a different project
- Changes to a different filler metal brand
Correct answer: Has not used that process for more than 6 months
Under AWS D1.1, if a welder has not used a specific process for 6 months or more, their qualification for that process expires.
Question 4: What is the difference between a supplementary essential variable and an essential variable in AWS procedures?
- There is no difference
- Supplementary essential variables apply only when notch-toughness requirements are specified (Correct answer)
- Essential variables apply only to SMAW
- Supplementary essential variables are used for cosmetic welds only
Correct answer: Supplementary essential variables apply only when notch-toughness requirements are specified
Supplementary essential variables become essential only when the code or contract specifies notch-toughness (impact) requirements.
Question 5: In AWS welder qualification, position designations 1G, 2G, 3G, and 4G refer to:
- Pipe positions
- Groove weld positions in plate (Correct answer)
- Fillet weld positions
- Tack weld positions
Correct answer: Groove weld positions in plate
Position designations 1G through 4G refer to groove weld positions in plate: flat, horizontal, vertical, and overhead.
Question 6: Welder qualification records may transfer to a new employer under AWS D1.1 if:
- OSHA approves the transfer
- The new employer accepts documented evidence of prior qualification testing (Correct answer)
- The union authorizes the transfer
- The welder retests on arrival
Correct answer: The new employer accepts documented evidence of prior qualification testing
Welder qualifications can transfer between employers when the new employer accepts documented evidence of prior qualification testing.
