Effect of Welding Current and Filler Metal Types on Percent Elongation of GTAW Austenitic Stainless Steel Weld Joints (Published)

This work is on the study of the effect of welding current and filler metal types on the percent elongation of 3mm thick austenitic steel (304L grade) welded joint. Five welding currents in the range of 91-95 amperes at 1 ampere interval and three filler metal types (ER308L, ER309L and ER316L) were used to produce square butt weld joints. The percent elongation was determined by carrying out tensile test using standard equipment and ASTM standard procedure. The results show that the percent elongation for all filler metal types increased with increase in welding current but were generally lower than that of the base metal.
