Introduction During the inspection of welding, multiple weld characteristics could be evaluated—several relevant to the size of the weld, & some other relevant to the presence of discontinuities of the weld. The weld size could be essential, as it usually directly relates to the strength of weld & its performance. Relying on their location and size, weld discontinuities could avoid the entire weld from reaching the required performance. Usually, the weld discontinuities are basically referred to defects of welding & sometimes they could make a premature failure of weld because of strength reduction or added concentration of stress within the components that are welded. For some reasons, inspections are carried out. A most common cause is to demonstrate whether the welding is of appropriate quality for application. For the evaluation of weld quality, you should have some criteria or standards to which individual could compare the characteristics of weld. Specifically, s...
