CWB 47.1 Exam (NEW UPDATED VERSION) LATEST ACTUAL EXAM
QUESTIONS AND CORRECT ANSWERS (VERIFIED QUESTIONS AND
ANSWERS) | GUARANTEED PASS A+ [2026]
1. Which of the following welding processes is permitted under CWB 47.1
for structural steel fabrication?
A) SMAW
B) GMAW
C) FCAW
D) All of the above
Rationale: CSA W47.1 allows multiple processes as long as the company, procedures, and welders
are certified.
2. What is the primary purpose of a WPS (Welding Procedure
Specification)?
A) To schedule welders
B) To provide instructions for producing a sound weld
C) To replace welder qualifications
D) To record inspection reports
Rationale: WPS ensures consistent, code-compliant welds.
3. In SMAW, what does the electrode designation E7018 indicate?
A) 70 ksi tensile, low-hydrogen coating
B) Flux-core electrode
C) Stainless steel rod
D) Aluminum rod
Rationale: E7018 is a low-hydrogen electrode with 70,000 psi tensile strength.

, 4. Which welding position is considered the easiest for most processes?
A) Overhead
Page | 2 B) Vertical
C) Flat
D) Horizontal
Rationale: Flat position allows optimal molten pool control.
5. What is the main purpose of preheat?
A) Make weld bead shinier
B) Reduce hardness and prevent cracking
C) Reduce heat input
D) Increase travel speed
Rationale: Preheat slows cooling, reducing hydrogen cracking risk.
6. A welder qualification test plate for CWB 47.1 must be supervised by:
A) Any foreman
B) A CWB Representative
C) A company manager
D) Any senior welder
Rationale: CWB reps ensure tests meet certification standards.
7. What is the most common discontinuity caused by low amperage?
A) Undercut
B) Lack of fusion
C) Porosity
D) Slag inclusion
Rationale: Insufficient heat prevents proper fusion.
EXAMPREPMASTER
, 8. Excessive travel speed typically causes:
A) Wider bead
B) Excessive penetration
C) Narrow bead + lack of fusion
Page | 3
D) Slag trapping
Rationale: Moving too fast reduces heat input.
9. Which gas is commonly used for GMAW on carbon steel?
A) Pure helium
B) Argon/CO₂ mix
C) Pure nitrogen
D) Oxygen
Rationale: 75/25 Ar-CO₂ gives stable arc and good penetration.
10. FCAW-S refers to flux-core wire that is:
A) Stainless only
B) Self-shielded
C) Gas-shielded
D) Used only indoors
Rationale: FCAW-S uses internal flux only.
11. What is the main purpose of interpass temperature control?
A) Maintain color
B) Reduce porosity
C) Prevent overheating or rapid cooling
D) Increase deposition
Rationale: Controls weld quality and prevents cracking.
