Question

question 14
having too long of an arc length can cause which of the following?
excessive convexity
undercut
excessive spatter
cold lap

Explanation:

In welding, when the arc length is too long, the shielding gas protection effect is reduced, and the molten metal is more likely to react with the air - borne oxygen and nitrogen, resulting in excessive spatter. Excessive convexity is usually related to welding parameters like current and speed rather than just arc length. Undercut is mainly due to incorrect welding speed or current distribution. Cold lap is related to insufficient fusion and improper welding sequence or speed.

Answer:

excessive spatter
