Research and application of dissimilar metal welding technology between SUS304 stainless steel and A53 carbon steel

Abstract

Dissimilar metal welding (DMW) process of composition and characteristic is difficultly. The weld is
require non-defect, stability microstructure and high strength. In this paper, author is study welding
processes between SUS304 stainless steel and A53 carbon steel by gas tungsten arc welding (GTAW)
and shielded metal arc welding (SMAW). Metallography method was used to analyzed metal
microstructure. Methods are non-destructive test (NDT) with radiography test (RT), destructive test
(DT) with strength tensile (TT) and face/root bending test (F/R-BT) to assessing welding quality.
