1. Which welding process uses a consumable electrode and shielding
gas?
a) SMAW
b) GMAW
c) FCAW
d) OAW
GMAW (Gas Metal Arc Welding) uses a consumable wire electrode
and a shielding gas to protect the weld pool from contamination.
2. What is the primary purpose of preheating a workpiece before
welding?
a) Reduce welding speed
b) Prevent cracking
c) Improve appearance
d) Increase electrode consumption
Preheating slows cooling, reducing the risk of thermal stress and
cracking in the weld.
3. In SMAW, what determines the correct welding current?
a) Electrode color
b) Electrode diameter and material
c) Ambient temperature
d) Gas flow rate
The electrode type and diameter dictate the amperage range for
proper fusion.
,4. Which welding process is commonly used for aluminum?
a) SMAW
b) GTAW
c) OAW
d) Stick welding
GTAW (TIG) provides precise control and produces high-quality
welds on aluminum.
5. What does AC current help reduce when welding aluminum?
a) Electrode melting
b) Oxide layer on the surface
c) Gas consumption
d) Heat input
AC helps break up the tough aluminum oxide layer for better
fusion.
6. Which of the following is considered a safety hazard in welding?
a) Proper PPE
b) UV radiation
c) Clean work area
d) Correct electrode storage
UV radiation from the arc can cause eye injury and skin burns.
7. What is the typical angle for holding a MIG welding gun relative to
the workpiece?
a) 90°
b) 0°
c) 15–20°
d) 45°
, Maintaining a 15–20° angle ensures proper weld bead formation
and penetration.
8. Which defect is caused by trapped gas in the weld metal?
a) Undercut
b) Porosity
c) Overlap
d) Slag inclusion
Porosity occurs when gas bubbles are trapped in solidifying weld
metal.
9. Which shielding gas is most commonly used for welding carbon
steel with GMAW?
a) Helium
b) Oxygen
c) Argon/CO₂ mixture
d) Hydrogen
An argon/CO₂ mixture provides stable arc and good penetration
for carbon steel.
10. What is the main advantage of flux-cored arc welding
(FCAW) over SMAW?
a) No power source needed
b) Faster deposition rate
c) No smoke produced
d) Requires no shielding
FCAW allows higher deposition rates and can be used with or
without shielding gas.
11. What is the function of a welding electrode flux coating?
a) Conduct electricity
