A ____ is an interruption in the typical structure of the weld, whereas a ____ is a flaw which renders the part unable to meet minimum acceptance standards.
A) tolerance, flaw
B) tolerance, discontinuity
C) failure, discontinuity
D) discontinuity, defect

Question

Quizplus · Accepted Answer

A discontinuity refers to any interruption in the continuity of the weld, while a defect refers to a specific type of discontinuity that causes the part to fall below minimum acceptance standards. Therefore, option D is the best choice. Option A is incorrect because tolerance refers to the allowable deviation from a specified dimension, not to weld quality. Option B is partly correct, but it does not differentiate between a discontinuity and a defect. Option C is incorrect because failure is not necessarily related to weld quality.
