Question

List 5 typical weld discontinuities that can be detected by radiography.

A) Inclusions, undercut, overlap, incomplete penetration, lack of fusion
B) Cracks, porosity, undercut, overlap, incomplete fusion
C) Voids, incomplete fusion, lack of fusion, underfill, overlap

Answer 1

The five typical weld discontinuities that can be detected by radiography are inclusions, undercut, overlap, incomplete penetration, and lack of fusion.

Step-by-step explanation:

The correct answer is A) Inclusions, undercut, overlap, incomplete penetration, and lack of fusion.

Inclusions are foreign material trapped in the weld, undercut is a groove at the weld toe, overlap is an excessive weld metal on the surface, incomplete penetration occurs when the weld does not fully penetrate the joint, and lack of fusion involves a discontinuity between the weld metal and base metal.
