1. What does the acronym NDE stand for in welding inspection?
A. Non-Destructive Evaluation
B. Non-Destructive Examination
C. National Design Engineering
D. New Development Equipment
Answer: B
NDE stands for Non-Destructive Examination, which refers to inspection
methods that evaluate welds without altering or destroying the component.
2. Which welding process uses a consumable electrode and a shielding gas?
A. SMAW
B. FCAW
C. GMAW
D. GTAW
Answer: C
GMAW (Gas Metal Arc Welding) uses a continuous consumable wire
electrode and an externally supplied shielding gas to protect the molten weld
pool from atmospheric contamination.
3. What is the primary purpose of preheating a weldment?
,A. To improve surface finish
B. To reduce the risk of cracking
C. To speed up cooling
D. To increase weld metal hardness
Answer: B
Preheating slows the cooling rate, which reduces thermal gradients and
minimizes the risk of hydrogen-induced cracking in the weld and heat-
affected zone.
4. Which of the following is NOT a typical welding defect?
A. Porosity
B. Undercut
C. Lack of fusion
D. Annealing
Answer: D
Annealing is a heat treatment process used to soften metal and relieve stress,
not a welding defect. Porosity, undercut, and lack of fusion are all common
weld discontinuities.
5. Which AWS standard specifically covers the qualification of welding
inspectors?
A. AWS D1.1
B. AWS B5.1
C. AWS A2.4
D. AWS A3.0
Answer: B
AWS B5.1 is the Specification for the Qualification of Welding Inspectors,
establishing requirements for education, experience, and examination of
inspection personnel.
6. What type of inspection method involves examining the surface of a weld
using a dye and developer?
, A. Radiographic testing
B. Ultrasonic testing
C. Magnetic particle testing
D. Liquid penetrant testing
Answer: D
Liquid penetrant testing (PT) relies on capillary action to draw a visible or
fluorescent dye into surface-breaking discontinuities, which are then revealed
by a developer.
7. Which of the following welding processes uses a non-consumable tungsten
electrode?
A. GMAW
B. FCAW
C. GTAW
D. SMAW
Answer: C
GTAW (Gas Tungsten Arc Welding), also known as TIG welding, uses a non-
consumable tungsten electrode to create the arc while filler metal may be
added separately.
8. What is the purpose of a welding procedure specification (WPS)?
A. To certify welders
B. To provide instructions for making a weld
C. To document inspection results
D. To specify base metal chemistry
Answer: B
A Welding Procedure Specification (WPS) provides the written instructions
and parameters for producing a weld that meets code requirements.
9. Which discontinuity is considered planar and generally the most serious?
A. Porosity
B. Slag inclusion
