Welding Cracks
Fracture-type interruptions either in weld or in base metal adjacent to weld
Serious defect because it is a discontinuity in the metal that significantly reduces strength
Caused by embrittlement or low ductility of weld and/or base metal combined with high restraint during contraction
In general, this defect must be repaired
