1. During layout for a structural steel fabrication project, a fabricator
notices that the shop drawing dimension differs from the contract
drawing by 3/8 inch. What is the most appropriate action?
A. Ignore the discrepancy because shop drawings always take
precedence
B. Modify the material to fit the shop drawing without approval
C. Stop fabrication of the affected member and request clarification
through the proper documentation process
D. Average both dimensions and proceed
Answer: C
Rationale: Contract documents govern the project unless officially
revised. Any dimensional discrepancy should be resolved before
fabrication to prevent costly rework, field fit-up problems, and structural
deficiencies.
2. Which ASTM structural steel grade is most commonly specified
for wide-flange beams used in commercial buildings?
A. ASTM A36
B. ASTM A992
C. ASTM A53
D. ASTM A514
1
,Answer: B
Rationale: ASTM A992 provides higher yield strength, excellent
weldability, and controlled chemical composition, making it the
standard material for modern structural wide-flange beams.
3. A beam measuring 24 feet is required to have a tolerance of ±1/16
inch. The fabricated beam measures 24 feet 3/16 inch. What should
the fabricator conclude?
A. Acceptable
B. Within erection tolerance
C. Outside fabrication tolerance
D. Can be corrected during bolting
Answer: C
Rationale: The member exceeds allowable fabrication tolerance by 1/8
inch and requires correction or engineering disposition before shipment.
4. Which measuring tool provides the highest precision when
verifying plate thickness?
A. Steel tape
B. Combination square
C. Outside micrometer
D. Framing square
Answer: C
Rationale: Micrometers provide precision typically within 0.001 inch,
making them ideal for measuring plate thickness accurately.
5. Why is mill scale often removed before welding?
2
,A. To reduce steel weight
B. To improve paint color
C. To prevent weld contamination and improve fusion
D. To reduce heat input
Answer: C
Rationale: Mill scale may trap impurities and interfere with proper
fusion, increasing the likelihood of weld discontinuities.
6. During oxyfuel cutting, excessive slag adheres to the bottom edge
of the plate. What is the most likely cause?
A. Oxygen pressure too low or travel speed incorrect
B. Plate too clean
C. Excess acetylene pressure only
D. Excessive plate thickness measurement
Answer: A
Rationale: Low oxygen pressure or improper travel speed commonly
produces poor-quality cuts with heavy slag accumulation.
7. Which plasma cutting advantage is greatest compared to oxyfuel
cutting?
A. Cuts only carbon steel
B. Cuts conductive metals rapidly with minimal heat distortion
C. Requires combustible gas only
D. Cannot cut stainless steel
Answer: B
Rationale: Plasma cutting efficiently cuts stainless steel, aluminum, and
carbon steel while producing narrower kerfs and lower heat input.
3
, 8. Which welding process generally offers the highest deposition rate
in automated structural fabrication?
A. SMAW
B. GTAW
C. SAW
D. OAW
Answer: C
Rationale: Submerged Arc Welding provides extremely high deposition
rates, deep penetration, and consistent weld quality for heavy structural
fabrication.
9. What is the primary purpose of preheating thick structural steel
before welding?
A. Increase paint adhesion
B. Reduce hydrogen cracking and control cooling rate
C. Improve cutting speed
D. Reduce weld reinforcement
Answer: B
Rationale: Preheating slows cooling, minimizes residual stress, and
reduces the risk of hydrogen-induced cracking.
10. Which discontinuity is characterized by incomplete joining
between weld metal and base metal?
A. Undercut
B. Lack of fusion
