1. A welding supervisor is reviewing a Welding Procedure
Specification (WPS) before production begins. What is the primary
purpose of the WPS?
A. To establish employee payroll classifications
B. To provide qualified welding parameters that produce acceptable
welds
C. To determine project costs
D. To replace inspection requirements
Answer: B. To provide qualified welding parameters that produce
acceptable welds
Rationale: A WPS provides essential variables such as base metal, filler
metal, amperage, voltage, travel speed, preheat, and technique that have
been qualified to consistently produce sound welds meeting code
requirements.
2. Which discontinuity is generally considered the most serious
because it can rapidly propagate under cyclic loading?
A. Undercut
B. Crack
1
,C. Overlap
D. Excessive reinforcement
Answer: B. Crack
Rationale: Cracks create sharp stress concentrations that significantly
reduce structural integrity. Under repeated loading, cracks grow quickly
and may lead to catastrophic failure.
3. During SMAW, excessive arc length typically causes:
A. Increased penetration
B. Lower spatter
C. Higher spatter and porosity
D. Reduced oxidation
Answer: C. Higher spatter and porosity
Rationale: An excessively long arc destabilizes shielding gases
generated by the electrode coating, allowing atmospheric contamination
that results in porosity and excessive spatter.
4. A welding supervisor observes frequent lack of fusion during
FCAW. Which corrective action is most appropriate?
A. Reduce voltage further
B. Increase heat input and improve electrode angle
C. Increase travel speed significantly
D. Reduce wire feed speed below recommended values
Answer: B. Increase heat input and improve electrode angle
2
,Rationale: Lack of fusion usually results from insufficient heat or
improper manipulation. Increasing heat input within qualified limits and
correcting electrode angle improves fusion.
5. Which shielding gas provides the deepest penetration during
GMAW of carbon steel?
A. 100% CO₂
B. 100% Argon
C. Helium
D. Nitrogen
Answer: A. 100% CO₂
Rationale: Pure CO₂ generally provides deeper penetration than argon-
rich mixtures but produces more spatter and a less stable arc.
6. A supervisor notices hydrogen-induced cracking several hours
after welding thick carbon steel. The most likely contributing
factor is:
A. Excessive travel speed only
B. Moist electrodes and inadequate preheat
C. Low amperage only
D. Improper paint color
Answer: B. Moist electrodes and inadequate preheat
Rationale: Hydrogen cracking requires diffusible hydrogen, susceptible
microstructure, and residual stress. Moist electrodes and insufficient
preheat greatly increase susceptibility.

, 7. Which electrode is classified as a low-hydrogen SMAW electrode?
A. E6010
B. E6011
C. E7018
D. E7024
Answer: C. E7018
Rationale: E7018 electrodes contain low-hydrogen flux coatings
designed to minimize hydrogen-induced cracking while producing high-
quality weld deposits.
8. The primary responsibility of a welding supervisor regarding
welder qualifications is to ensure:
A. Every welder has identical equipment
B. Welders are qualified for the applicable process, position, and
procedure
C. Welders own personal welding machines
D. Welders perform only overhead welding
Answer: B. Welders are qualified for the applicable process,
position, and procedure
Rationale: Codes require welders to demonstrate competency for
specific welding processes, positions, materials, and essential variables.
9. Which NDT method is best suited for detecting internal volumetric
defects?
