9. Welding Defects 110 poor power, lack of fusion is the result. With too high heat input, i.e. too low welding speed, the weld pool gets too large and starts to flow away in the area in front of the arc.
Improper grinding may result in numerous surface defects, e.g., retempered areas, rehardened areas, and cracks. Heat treatment errors often result in regions of decreased hardness, i.e., soft spots, as well as decarburizing, denitriding, or overtempering. If left undetected, each of these defects may lead to catastrophic failure
