Testing & Inspection Methods
A variety of inspection and testing methods are available to check the quality
of the welded joint.
The inspection and testing procedures can be divided into three categories:
 Visual Inspection
 Destructive Tests, and
 Non-destructive tests.

 Destructive Tests
 Tension test
Tensile test specimen can be either transverse or
longitudinal depends on the loading on the welded joint.
In tension test, strength, elongation and reduction area
are of primary importance
