A Discontinuity is an objective lack of material, an interruption in the physical consistence of a part while a Defect is an excessive conditions, outside the acceptance limits, which risks to compromise the stability or the functionality of the welded structure.

It is very hard to perfect welding. Most often, the pressence of discontinuity is there. Codes and standards set the acceptability of discontinuities in a weld. When the size of the discontinuity exceeds the size permitted in a certain code or standard, then that will be called defect, which needs to be repaired.
