What are destructive test in welding ?

1. Tension test

Tension tests examine yield strength, tensile strength, elongation and reduction in area by stretching a tension test specimen until it ruptures. The tension tests of a weld metal and a welded joint are conducted according to the specification to be followed.

For fillet welds, the shearing strength of fillet joints is examined, using a tension test machine.

2. Bend test

Bend tests examine the ductility of welds and whether they contain welding defects or not.

Bend test specimens are usually removed from butt weld joints so that the weld is perpendicular to the longitudinal axis of the specimen.

In bend tests, three different types of specimens are used, depending on the surface to be tested:
