| Abstract | ||
| In the present work, plates made from 316L and 304L stainless steels (SS) were joined using gas tungsten arc welding (GTAW) to form similar and dissimilar welded joints. The welding process were conducted using ER308L filler rods and constant welding parameters, typically, welding voltage, welding current, and welding speed. Regression modelling was used to corelate the tensile characteristics of the 316L and 314L similar and dissimilar welded SS joints with or without elevated temperature. The results revealed that regression models for ultimate tensile strength (UTS), yield strength (YS) and ductility (elongation, E%) exhibited R-square values of 0.95, 0.91 and 0.74, respectively. The developed regression models can roughly predict the tensile characteristics of similar and dissimilar 304L and 316L SS welded joints. | ||
