Question

what happens if the tungsten electrode contacts the weld pool during gtaw?
a the electrode becomes contaminated.
b the arc becomes more concentrated.
c the weld becomes more stable.
d the amperage is automatically reduced.

Explanation:

In Gas Tungsten Arc Welding (GTAW), the tungsten electrode must remain pure to maintain arc stability and weld quality. Contact with the molten weld pool transfers contaminants from the pool to the electrode, altering its composition and performance.

Answer:

A. The electrode becomes contaminated.
