摘要：

In this study, AISI 316 L types of austenitic stainless steels are welded by GTAW (gas tungsten arc welding) using 430L and 2209 filler metals, respectively. Mechanical properties of 316L austenitic stainless steel weldments, such as tensile properties, hardness and impact properties are determined. GTA weld microstructures are presented by optical microscopy with 1000X magnifications of weld metal region. The values obtained for ultimate tensile strength, yield strength and percentage of elongation for the welded joints are compared to the data obtained. From this investigation, the result shows that the yield, tensile strength and impact energy values of 316L stainless steels welded by GTAW using 2209 filler metal is superior compared to 430L filler metal.
