1. Which AWS/AASHTO code is specifically intended to govern welding requirements for
welded bridges designed to AASHTO or AREMA requirements?
A. AWS D1.1/D1.1M
B. AWS D1.2/D1.2M
C. AASHTO/AWS D1.5M/D1.5
D. AWS D1.4/D1.4M
Answer: C
The D1.5 Bridge Welding Code addresses welding requirements for bridges constructed from
carbon and low-alloy constructional steels under AASHTO or AREMA requirements.
2. Before beginning production welding on a bridge component, what document should the
welder use to determine the authorized welding variables?
A. Welding Procedure Specification (WPS)
B. Material Test Report (MTR)
C. Inspection Report
D. Welder Continuity Record
Answer: A
The WPS establishes the welding variables and requirements that the welder is expected to
follow during production welding.
3. A welder is asked to change a welding variable outside the qualified range listed on the
applicable procedure. What should the welder do first?
A. Make the change if the weld appearance improves
B. Increase the current gradually until the weld stabilizes
C. Ask another welder whether the change is acceptable
D. Stop and obtain authorization under an applicable qualified procedure
Answer: D
Production welding must remain within the applicable qualified requirements. A change
outside the authorized range should not be made simply on the welder's judgment.
,4. What is the primary purpose of a Welding Procedure Specification?
A. To record the final inspection results
B. To define the variables and requirements for producing an acceptable weld
C. To certify the chemical composition of the base metal
D. To replace welder qualification records
Answer: B
A WPS provides controlled welding instructions, including applicable variables and
requirements needed to produce compliant welds.
5. During preweld inspection, a welder discovers that the joint preparation does not match
the approved WPS. What is the most appropriate action?
A. Weld the joint because fit-up is normally the fabricator's responsibility
B. Increase heat input to compensate
C. Stop and have the discrepancy resolved before welding
D. Modify the joint personally without documentation
Answer: C
Joint preparation is an important welding variable. Welding should not proceed when the
actual joint differs from the applicable requirements unless the discrepancy is properly
resolved.
6. Which condition is most directly associated with inadequate shielding during gas-
shielded welding?
A. Porosity
B. Excessive reinforcement only
C. Lamellar tearing
D. Undersize plate thickness
Answer: A
Loss or disruption of shielding can allow atmospheric contamination of the molten weld pool,
producing porosity and other weld-quality problems.
7. Why is preheat used when required by the applicable welding procedure?
A. To eliminate the need for interpass temperature control
B. To increase electrode deposition efficiency
C. To guarantee complete penetration regardless of joint design
D. To control cooling behavior and reduce the risk of hydrogen-related cracking
,Answer: D
Required preheat influences the cooling rate of the weld and heat-affected zone and helps
reduce the risk of hydrogen-assisted cracking.
8. A welder notices excessive moisture on a joint immediately before welding. What is the
best response?
A. Weld through the moisture using higher amperage
B. Remove the moisture and address the source before welding
C. Cover the area with additional filler metal
D. Reduce travel speed until the moisture evaporates
Answer: B
Moisture can introduce hydrogen and other contaminants into the welding process. The joint
should be properly dried and the source controlled before welding.
9. Which document records qualification test information for a welding procedure?
A. WPS
B. PQR
C. MTR
D. NCR
Answer: B
The Procedure Qualification Record documents the actual variables and test results used to
demonstrate that a welding procedure can meet the specified requirements.
10. A welder's performance qualification primarily demonstrates what?
A. That the welder can produce sound welds under specified qualified conditions
B. That the welder can design bridge members
C. That the welder can approve engineering drawings
D. That the welder can perform nondestructive examination
Answer: A
Performance qualification demonstrates the welder's ability to produce acceptable welds
within specified qualification variables.
11. Which factor is particularly important when determining whether a consumable is
appropriate for a bridge weld?
, A. Electrode packaging color
B. Welder preference
C. Applicable specification and required mechanical properties
D. Length of the welding lead
Answer: C
Consumables must meet the applicable specification and provide properties compatible with
the qualified welding procedure and base material.
12. A low-hydrogen electrode has been exposed to conditions outside its permitted storage
requirements. What is the primary concern?
A. Excessive electrode length
B. Reduced arc brightness
C. Increased deposition rate
D. Moisture pickup and increased hydrogen potential
Answer: D
Improper storage can allow moisture absorption, increasing hydrogen availability and
potentially contributing to hydrogen-assisted cracking.
13. What is the principal reason for controlling interpass temperature?
A. To maintain the weld's required thermal conditions
B. To make every weld visually identical
C. To eliminate the need for preheat
D. To increase welding voltage automatically
Answer: A
Interpass temperature control helps maintain the thermal conditions required by the qualified
procedure and protects weld and base-metal properties.
14. Which welding discontinuity consists of gas trapped within the solidified weld metal?
A. Undercut
B. Porosity
C. Overlap
D. Incomplete fusion
Answer: B
Porosity is formed when gas becomes trapped in the weld metal during solidification.
