For today's lesson our topic is still a continuation of Welding Defects.
Arc Strikes - a discontinuity consisting of any localized re-melted metal, heat effected metal, or change in surface profile of a finished weld or base material surface resulting from an electric arc.
Overlap - metal flowing onto the surface of the parent metal without fusing to it.
Excessive Convexity - to much weld metal added to the joint so that the weld is not shaped correctly.
Excessive Concavity - not enough weld metal added.
