1. Which welding process uses a continuously fed consumable wire
electrode and external shielding gas?
A. SMAW
B. GTAW
, C. GMAW
D. Oxyfuel welding
Answer: C
Correct Answer: GMAW
Gas Metal Arc Welding uses a continuously fed wire electrode and
shielding gas supplied externally.
2. In SMAW, the shielding of the weld pool is primarily provided by:
A. Argon gas
B. CO₂ gas
C. Flux coating on the electrode
D. Helium
Answer: C
Correct Answer: Flux coating on the electrode
The electrode coating decomposes to create shielding gas and slag that
protect the molten weld pool.
3. The 3G welding position refers to:
A. Flat position groove weld
B. Horizontal groove weld
C. Vertical groove weld
D. Overhead groove weld
Answer: C
Correct Answer: Vertical groove weld
3G designates a vertical groove weld position under AWS standards.
4. Excessive amperage in SMAW can result in:
A. Lack of fusion
B. Undercut
, C. Slag inclusion
D. Porosity
Answer: B
Correct Answer: Undercut
Too much heat melts the base metal edges excessively, causing undercut
along the weld toe.
5. Porosity in weld metal is primarily caused by:
A. Excessive travel speed
B. Improper shielding
C. Low amperage
D. Small electrode diameter
Answer: B
Correct Answer: Improper shielding
Contamination or insufficient shielding gas allows atmospheric gases to
enter the weld pool.
6. The primary purpose of preheating carbon steel before welding is
to:
A. Increase travel speed
B. Reduce hydrogen cracking
C. Improve bead appearance
D. Increase penetration
Answer: B
Correct Answer: Reduce hydrogen cracking
Preheat slows cooling rate and reduces the risk of hydrogen-induced
cracking.
, 7. E7018 electrode classification indicates minimum tensile strength
of:
A. 60,000 psi
B. 70,000 psi
C. 18,000 psi
D. 100,000 psi
Answer: B
Correct Answer: 70,000 psi
The first two digits in E7018 represent 70 ksi tensile strength.
8. The root pass in a groove weld is primarily intended to:
A. Improve appearance
B. Seal the joint and ensure penetration
C. Remove slag
D. Increase reinforcement
Answer: B
Correct Answer: Seal the joint and ensure penetration
The root pass establishes proper penetration at the joint root.
9. FCAW differs from GMAW because FCAW:
A. Uses no electrode
B. Uses flux within the wire
C. Requires no power source
D. Uses only DCEN
Answer: B
Correct Answer: Uses flux within the wire
Flux-Cored Arc Welding incorporates flux in the tubular electrode.
