Red Seal Welder Exam (Interprovincial)
D. Welding processes: practice questions
Our Red Seal Welder bank has 134 questions on this topic. Here are 5 of them with answers; the full mock exam draws from every topic, like the real one.
Question 1
When running a GTAW butt weld, what torch angle does the manual give after forming the puddle?
- About 15° to the work surface
- About 30° to the work surface
- Flat along the work surface
- About 75° to the work surface
Show the answer
D. About 75° to the work surface — Hold the torch at a 75-degree angle to the work and move it steadily along the joint.
Question 2
For GMAW of thin steel (0.035 to 1/8 in.), the Steelworker manual recommends:
- A 60° bevel on both edges with a 1/4 in. root opening and backing
- A backing bar of copper and 1/8 in. gap
- No edge preparation and a root opening of 1/16 in. or less
- Gouging both sides
Show the answer
C. No edge preparation and a root opening of 1/16 in. or less — For thin materials no edge preparation is needed and a root opening of 1/16 in. or less is recommended.
Question 3
For GTAW of thin material in the vertical position, the Steelworker manual suggests welding:
- From the bottom, moving upward only
- Horizontally across the joint
- From the top, moving downward
- With no filler at all
Show the answer
C. From the top, moving downward — When welding thin material vertically with GTA, weld from the top downward.
Question 4
For GMAW of carbon steel plate 1/4 in. or thicker, the manual recommends a V-groove with an included angle of:
- 10° to 15°
- 90° to 100°
- 50° to 60°
- No groove at all
Show the answer
C. 50° to 60° — When welding plates 1/4 in. or thicker, prepare a single or double V-groove with 50- to 60-degree included angle.
Question 5
In the classification E6010, the third digit '1' means the electrode can be used:
- Only flat and horizontal
- Only vertical down
- In all positions
- Only on aluminum
Show the answer
C. In all positions — The third digit is position: 1 = any position, 2 = flat and horizontal only.
