Q&A| Instant Download Pdf
1. Which ASTM standard establishes tolerances for structural steel
welds?
A. AWS D1.1
B. ASTM A6
C. ASTM E1444
D. ISO 9001
Rationale: ASTM A6 specifies general requirements for delivery
conditions, tolerances, and markings for structural steel, including
weld tolerances.
2. What is the primary purpose of performing a magnetic particle
inspection on structural steel?
A. To measure thickness
B. To determine chemical composition
C. To detect surface and near-surface discontinuities
D. To assess hardness
Rationale: Magnetic particle inspection is used to reveal surface and
slightly subsurface cracks or defects in ferromagnetic materials.
,3. In bolted connections, what is the minimum acceptable torque
method requirement for high-strength bolts per RCSC?
A. Turn-of-nut only
B. Calibrated wrench only
C. Turn-of-nut or calibrated wrench depending on condition
D. No requirement
Rationale: RCSC provisions allow controlled tightening either by
turn-of-nut or calibrated wrench methods depending on installation
conditions.
4. What does “fit-up” refer to in structural steel inspection?
A. The welding sequence
B. Painting schedule
C. Alignment and preparation of parts before welding
D. Bolt tightening order
Rationale: Fit-up describes positioning, aligning, and adjusting
members prior to welding to ensure correct assembly.
5. Which nondestructive testing method is most suitable for detecting
subsurface inclusions?
A. Visual inspection
B. Magnetic particle
C. Ultrasonic testing
D. Liquid penetrant
Rationale: Ultrasonic testing can detect internal flaws by reflecting
sound waves off discontinuities within the material.
6. What is the primary concern addressed by SSPC-PA 2?
A. Welding procedures
B. Field abrasive blast cleaning quality
C. Bolt torque specifications
D. Concrete embedment
, Rationale: SSPC-PA 2 establishes surface preparation criteria for
abrasive blast cleaning prior to coating application.
7. Which inspector responsibility is required before welding begins?
A. Final coat inspection
B. Stress relief heat treatment
C. Pre-weld fit verification
D. Load testing
Rationale: Pre-weld fit verification ensures components are correctly
aligned and meet tolerances before welding starts.
8. What does the weld discontinuity “incomplete penetration” mean?
A. Excessive weld reinforcement
B. Porosity
C. Failure of weld metal to fuse through the joint thickness
D. Undercut
Rationale: Incomplete penetration is when the weld metal does not
extend through the joint thickness as required.
9. Which coating inspection test measures dry film thickness?
A. Holiday test
B. Magnetic gauge reading
C. Ultrasonic thickness
D. Tensile test
Rationale: Magnetic gauge readings quantify the thickness of dry
protective coatings on steel surfaces.
10. What is the acceptable maximum weld undersize per AWS D1.1
for fillet welds?
A. 0.5 mm
B. 1/16 in.
C. 3/32 in.
D. No limit
