1. During fabrication of a structural steel component for a Louisiana
transportation project, the inspector discovers that the heat number
marked on a plate does not correspond to the material test report
submitted for that plate. What is the most appropriate initial
inspection action?
A. Allow fabrication to continue because the plate dimensions are
correct
B. Require the fabricator to grind off the existing heat number and
replace it with the correct number
C. Place the affected material on hold and verify material identity and
traceability before acceptance
D. Accept the material if the fabricator provides a verbal statement
confirming the steel grade
Answer: C. Place the affected material on hold and verify material
identity and traceability before acceptance
Rationale: Material traceability is fundamental to fabrication
inspection. The inspector must be able to establish that the physical
material being incorporated into the work corresponds to the approved
material documentation, including the applicable heat, grade,
specification, and test results. Altering markings without establishing
the original identity can destroy traceability.

,2. A fabrication shop receives several steel plates intended for
different bridge members. The inspector observes that the plates are
stored together without individual identification. Why is this
condition particularly significant?
A. It can make dimensional inspection more difficult
B. It can compromise material traceability and create a risk of using the
wrong grade or heat
C. It automatically causes every plate to become defective
D. It only matters after welding has begun
Answer: B. It can compromise material traceability and create a
risk of using the wrong grade or heat
Rationale: Proper identification and segregation allow inspectors and
fabricators to trace material from receipt through cutting, fabrication,
welding, inspection, and final assembly. Mixing unidentified materials
creates the possibility of incorporating material with an incorrect
grade, heat, thickness, or certification into the finished structure.
3. Before structural steel fabrication begins, an inspector reviews the
approved shop drawings. Which information is most important
when determining whether the fabrication operation is proceeding
according to the contract requirements?
A. The color of the fabrication equipment
B. The approved dimensions, details, material specifications, weld
requirements, tolerances, and applicable notes
C. The number of employees working in the shop
D. The age of the welding machines
Answer: B. The approved dimensions, details, material
specifications, weld requirements, tolerances, and applicable notes
2
,Rationale: Shop drawings provide the fabrication-specific details
necessary to construct the component correctly. Inspection must
compare actual fabrication against the approved drawings, contract
requirements, specifications, welding requirements, dimensions,
tolerances, and details.
4. A steel plate is found to contain surface laminations during visual
examination before fabrication. What should the inspector do?
A. Ignore the condition because laminations are always removed during
painting
B. Accept the plate if the plate thickness is greater than specified
C. Document the condition and require evaluation in accordance with
the applicable material and project requirements
D. Permit the fabricator to weld directly over the lamination
Answer: C. Document the condition and require evaluation in
accordance with the applicable material and project requirements
Rationale: Laminations can represent internal discontinuities that
affect structural integrity, particularly when located in areas subject to
significant stress or when they interfere with fabrication. The
inspector should document the condition and have it evaluated
according to the governing requirements rather than unilaterally
accepting or repairing it.
5. Why is preheat control important during welding of structural
steel?
A. It primarily improves the color of the weld
B. It reduces the risk of undesirable thermal effects, including hydrogen-
related cracking
3
, C. It eliminates the need for qualified welders
D. It guarantees that nondestructive testing will not be required
Answer: B. It reduces the risk of undesirable thermal effects,
including hydrogen-related cracking
Rationale: Appropriate preheat helps control cooling rates and
reduces the potential for hydrogen-assisted cracking and other weld-
related problems. Required preheat temperatures depend on the
applicable welding procedure, base material, thickness, welding
process, and governing specification.
6. A welder begins welding a critical structural joint using a welding
procedure that has not been approved or qualified for the materials
and joint configuration involved. What is the primary inspection
concern?
A. The weld may have excessive paint
B. The weld may not meet the required qualified welding procedure
requirements
C. The welder may work too quickly
D. The steel may become too shiny
Answer: B. The weld may not meet the required qualified welding
procedure requirements
Rationale: Structural welding must be performed using an applicable
and properly qualified welding procedure. The procedure establishes
essential variables such as materials, welding process, electrode
classification, joint configuration, preheat, interpass temperature,
amperage, voltage, travel speed, and other requirements.
