1. A Texas welding inspector is reviewing a structural steel weld that
must comply with AWS D1.1. Which inspection activity should
always occur before welding begins?
A. Conduct radiographic testing immediately
B. Verify base materials, joint preparation, WPS, and welder
qualifications
C. Polish all weld surfaces
D. Perform magnetic particle testing
Answer: B
Rationale: Pre-weld inspection is one of the most important
responsibilities of a welding inspector. The inspector must verify the
approved Welding Procedure Specification (WPS), confirm welder
qualifications, inspect base materials, joint fit-up, cleanliness,
dimensions, and environmental conditions before any welding starts.
Detecting problems before welding prevents costly repairs later.
2. Which document provides detailed instructions for producing a
weld under specific conditions?
A. PQR
B. WPS
1
,C. WPQ
D. MTR
Answer: B
Rationale: The Welding Procedure Specification (WPS) is the written
document directing the welder regarding joint design, welding process,
filler metal, amperage, voltage, travel speed, shielding gas, and preheat
requirements.
3. What is the primary purpose of a Procedure Qualification Record
(PQR)?
A. Certify inspectors
B. Record successful test results proving a welding procedure
C. Measure weld size
D. Record daily production
Answer: B
Rationale: A PQR documents actual variables and test results from a
qualification weld. Mechanical testing demonstrates the procedure can
produce acceptable welds.
4. During visual inspection, undercut is defined as:
A. Excessive reinforcement
B. A groove melted into the base metal adjacent to the weld toe and left
unfilled
C. Slag trapped inside weld metal
D. Surface discoloration
Answer: B
2
,Rationale: Undercut reduces cross-sectional thickness and creates
stress concentration points that can significantly decrease fatigue
strength.
5. Which NDT method is best suited for detecting internal volumetric
discontinuities?
A. Visual Testing
B. Liquid Penetrant Testing
C. Radiographic Testing
D. Magnetic Particle Testing
Answer: C
Rationale: Radiographic testing effectively detects porosity, slag
inclusions, lack of fusion, and other internal volumetric discontinuities
by recording density differences on film or digital detectors.
6. Lack of fusion occurs when:
A. Weld metal completely melts into base metal
B. Weld metal fails to fuse with the base metal or previous weld bead
C. The weld reinforcement is excessive
D. The weld is polished too aggressively
Answer: B
Rationale: Lack of fusion is one of the most serious weld discontinuities
because it significantly weakens the joint and may not be visible
externally.
7. Excessive welding current most commonly causes:
3
, A. Narrow bead
B. Undercut and excessive penetration
C. Cold lap
D. Lack of penetration only
Answer: B
Rationale: High amperage increases heat input, producing deeper
penetration and increasing the risk of undercut and burn-through.
8. Which welding process continuously feeds a consumable wire
electrode?
A. GTAW
B. SMAW
C. GMAW
D. Oxyfuel Welding
Answer: C
Rationale: Gas Metal Arc Welding (GMAW/MIG) uses a continuously
fed consumable wire and shielding gas.
9. Which process normally uses a non-consumable tungsten
electrode?
A. FCAW
B. GMAW
C. GTAW
D. SMAW
Answer: C
