Which welding process uses a continuously fed wire and shielding gas?
Answer: Gas Metal Arc Welding (GMAW)
Gas Metal Arc Welding (GMAW), also known as MIG welding, uses a wire feed and shielding gas to protect the weld.
What is the primary function of a flux in welding?
Answer: Protect the weld from contaminants
Flux prevents oxidation and contamination by producing a shielding gas and slag over the weld area.
Which welding process uses a non-consumable tungsten electrode?
Answer: GTAW
Gas Tungsten Arc Welding (GTAW or TIG) uses a tungsten electrode that does not melt during welding.
Which process is best suited for outdoor welding applications?
Answer: SMAW
Shielded Metal Arc Welding (SMAW) is ideal for outdoor work due to its built-in flux that protects the weld from wind and contaminants.
What does the term 'arc length' refer to in arc welding?
Answer: Distance between the electrode and the workpiece
Arc length is the distance between the tip of the electrode and the workpiece, and it influences bead shape and penetration.
Which welding process is known for producing the cleanest welds with high precision?
Answer: GTAW
GTAW (TIG welding) produces clean, precise welds and is often used in aerospace and food-grade applications.
