Red Seal Welder Exam (Interprovincial)
B. Layout and fabrication: practice questions
Our Red Seal Welder bank has 68 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
Which jig or fixture benefit matters most when making many identical parts?
- Parts are held in the same position every time
- The welder needs no PPE
- No tack welds are ever needed when a jig is used for welding
- The weld size can be smaller
Show the answer
A. Parts are held in the same position every time — Jigs and fixtures speed production and keep parts aligned and repeatable, and they restrain distortion.
Question 2
What is the main reason for bevelling the edges of thick plate before welding a butt joint?
- To reduce the amount of filler metal needed to almost nothing
- To remove the mill scale only
- To allow welding without preheat
- To allow complete penetration through the thickness
Show the answer
D. To allow complete penetration through the thickness — Edge preparation gives access to the root so the weld can fuse through the full plate thickness.
Question 3
What is the main purpose of tack welds during fit-up?
- To provide the full design strength of the finished joint
- To preheat the joint
- To test the electrode
- To hold parts in alignment until final welding
Show the answer
D. To hold parts in alignment until final welding — Tack welds hold the parts in position and alignment; they must be sound because they often become part of the final weld.
Question 4
A square-to-round transition is normally laid out by:
- Parallel line development
- Radial line development
- Triangulation
- Simple scaling
Show the answer
C. Triangulation — Triangulation divides irregular surfaces such as transitions into triangles whose true lengths are found and laid out.
Question 5
What is the cut angle for each joint of a 2-piece 90° mitred elbow?
- 22.5°
- 45°
- 30°
- 15°
Show the answer
B. 45° — A 90° turn made with one joint (two pieces) needs 90 ÷ 2 = 45° on each piece.
