1. A welding supervisor observes that welders are producing acceptable
welds, but productivity is consistently below the planned rate. Which action
should be taken FIRST?
A. Increase welding current for all welders
B. Require welders to work faster
C. Analyze the causes of lost welding time and identify process bottlenecks
D. Reduce inspection requirements
Rationale: Productivity improvement begins by identifying where and why
productive time is being lost. Increasing parameters or pressuring workers
without identifying the root cause can create quality problems or morale
issues.
2. Which document primarily provides the detailed welding variables and
instructions that a welder is required to follow during production?
A. Material Test Report
B. Welding Procedure Specification
C. Inspection Report
D. Purchase Order
Rationale: The WPS establishes the welding variables and instructions
necessary to produce a sound weld under specified conditions. It is the
controlling document for production welding.
,3. Which change would normally have the greatest direct effect on weld
deposition rate in a wire-fed arc welding process?
A. Increasing wire feed speed
B. Changing the color of the shielding-gas hose
C. Increasing electrode stick-out without changing other variables
D. Changing the workpiece identification number
Rationale: In wire-fed processes, wire feed speed is directly related to
electrode melting rate and therefore strongly affects deposition rate.
4. A supervisor discovers that several welders are using a welding procedure
that is different from the approved WPS. What is the most appropriate
immediate action?
A. Allow the work to continue if the welds look acceptable
B. Stop the affected work and determine whether the procedure is authorized
C. Increase inspection frequency only
D. Change the acceptance criteria
Rationale: Production welds must be made in accordance with the applicable
approved requirements. Visual appearance alone does not establish
compliance with a qualified procedure.
5. Which factor generally has the greatest influence on heat input during arc
welding?
A. Arc voltage and welding current together with travel speed
B. Electrode color
C. Workpiece identification number
D. Welding booth size
Rationale: Heat input is primarily related to electrical energy supplied
(voltage × current) and the rate at which the electrode travels along the joint.
6. What is the principal reason for controlling preheat when welding
susceptible steels?
A. To increase welding machine efficiency
B. To reduce the possibility of hydrogen-assisted cracking and control cooling
rate
, C. To eliminate the need for inspection
D. To increase electrode diameter
Rationale: Preheat slows cooling and can reduce the risk of cracking by
influencing hydrogen diffusion and the formation of hard microstructures.
7. A welding supervisor notices excessive porosity in several welds made with
a gas-shielded process. Which condition should be investigated FIRST?
A. Shielding-gas coverage
B. Weld symbol size
C. Electrode storage rack color
D. Material identification number only
Rationale: Porosity in gas-shielded welding is commonly associated with
inadequate or contaminated shielding, leaks, excessive gas flow, drafts, or
improper torch positioning.
8. What is the primary purpose of a welding procedure qualification record?
A. To document evidence that a welding procedure can produce acceptable
welds under specified conditions
B. To record daily attendance
C. To calculate employee wages
D. To replace all production inspection reports
Rationale: A PQR records the actual variables and test results associated with
qualification of a welding procedure.
9. Which welding process normally uses a continuously fed consumable
electrode and an externally supplied shielding gas?
A. GTAW
B. GMAW
C. SMAW
D. Oxyfuel welding
Rationale: Gas Metal Arc Welding uses a continuously fed wire electrode and
shielding gas supplied from an external source.
10. What is the primary responsibility of a welding supervisor in a production
environment?
A. Designing all welded structures
