Abstract
In the present work, visual inspection and X-ray radiographic test has been conducted in order to detect surface and sub-surface
defects of weld specimens made of AISI 316L austenitic stainless steels. Effect of current, gas flow rate and nozzle to plate
distance on quality of weld in metal inter gas arc welding of AISI 316L austenitic stainless steel has been studied in the
present work through experiments and analyses. Butt welded joints have been made by using several levels of current, gas
flow rate and nozzle to plate distance. The quality of the weld has been evaluated in terms of yield strength, ultimate tensile
strength and percentage of elongation of the welded specimens. The observed data have been interpreted, discussed and
analyzed by using Grey - Taguchi methodology
