Abstract
The present paper reports the weld quality evaluations carried on EN-08 mild steel samples fabricated with Tungsten Inert Gas (TIG) welding process. Different weld inspection techniques are applied on the welds and the details of weld defects analysis has been carried. Ultrasonic tests and Gamma and X-ray radiography methods are useful to find the internal weld joint defects. Liquid penetration and magnetic particle inspection techniques are suitable for surface and subsurface defects in weld samples. The kind of the weld defects and their nature in terms of the weld defect quantification and quality evaluation with each applicable NDT techniques is highlighted.
