True or False
Destructive Testing employs various methods that evaluates welds without impairing their function and usefulness.
False
Which test checks for ductility?
shear test
free-bend test
nick-break test
free-bend test
True or False
A tensile strength testing machine can perform both a tensile strength test and a shear test which pull the welded pieces until they break.
True
The purpose of this test is to check the fractured weld surface for porosity, gas pockets, slag inclusions, overlaps, penetration, and grain size.
