Which welding process is commonly referred to as stick welding?
Shielded Metal Arc Welding (SMAW) is often known as stick welding due to its use of a consumable electrode.
Which welding process uses a shielding gas and a non-consumable electrode?
GTAW (also known as TIG) uses a tungsten electrode that does not melt during the welding process.
Which technique is ideal for high-precision welds on thin materials?
TIG welding is known for its precision and is excellent for welding thin metals such as aluminum and stainless steel.
What does GMAW stand for?
Gas Metal Arc Welding (GMAW) is commonly referred to as MIG welding.
Which process is often used in heavy construction and uses a flux core wire?
Flux-Cored Arc Welding (FCAW) is widely used in industrial and outdoor settings due to its portability and deep penetration.
What type of current is typically used for TIG welding on aluminum?
Alternating Current (AC) is generally used for TIG welding aluminum due to its cleaning action and penetration capabilities.

Which of the following processes is most automated?
Submerged Arc Welding (SAW) is highly automated and used in manufacturing for its speed and consistency.
Why is MIG welding popular among beginners?
MIG welding is easier to learn, produces clean welds, and uses a continuous wire feed, making it ideal for new welders.
What is the primary function of shielding gas in arc welding?
Shielding gas protects the weld pool from atmospheric contamination that can cause defects.
