AWS CERTIFIED WELDER PRACTICE EXAM 1
QUESTIONS AND CORRECT ANSWERS
(VERIFIED ANSWERS) PLUS RATIONALES
2025
Question 1
What is the primary purpose of a welding procedure specification (WPS)?
A) To list the personal protective equipment required
B) To provide detailed welding parameters and techniques to ensure consistent
weld quality
C) To describe the visual inspection criteria
D) To certify the welder’s qualifications
Answer: B
Rationale: The WPS provides detailed instructions on welding parameters and
techniques to ensure welds are made consistently and meet code requirements.
Question 2
,Which of the following welding processes uses a non-consumable tungsten
electrode?
A) Shielded Metal Arc Welding (SMAW)
B) Gas Metal Arc Welding (GMAW)
C) Gas Tungsten Arc Welding (GTAW)
D) Flux-Cored Arc Welding (FCAW)
Answer: C
Rationale: GTAW (TIG welding) uses a non-consumable tungsten electrode to
produce the weld.
Question 3
What is the most common shielding gas used in Gas Metal Arc Welding (GMAW)
for welding carbon steel?
A) Argon
B) Oxygen
C) Carbon Dioxide (CO2)
D) Helium
Answer: C
Rationale: CO2 is commonly used as a shielding gas in GMAW because it provides
good arc stability and weld penetration for carbon steel.
Question 4
, What does the welding term “slag” refer to?
A) The molten metal pool during welding
B) The solidified residue left on the weld bead after welding
C) The electrode used for welding
D) The protective gas around the weld
Answer: B
Rationale: Slag is the solidified residue from flux that covers and protects the
weld bead during cooling.
Question 5
Which welding position is described as “flat” (1G or 1F)?
A) Welding on a vertical surface
B) Welding overhead
C) Welding on a horizontal surface from above
D) Welding in a horizontal groove
Answer: C
Rationale: The flat position means welding is performed on the upper side of the
joint, allowing the weld pool to rest in the normal downward direction.
Question 6
What is the primary hazard when welding galvanized steel?
A) Electric shock
B) Exposure to zinc oxide fumes
