Welding of ferritic stainless steel plate using austenitic stainless steel electrode

Abstract

Abstract In this study, microstructure and phase transformation of ferritic stainless steel plate 405 using austenitic stainless steel 309-16L electrode was explained. Shielded Metal Arc Welding SMAW was used. Optical microscopy OM and scanning electron microscopy SEM were conducted to evaluate the morphology and structure of weld metal and heat-affected zone. X-ray diffraction also used to determine the crystal structure that developed during welding of bcc crystal structure and fcc crystal structure. Energy-dispersive X-ray spectroscopy EDS was used to evaluate the chemistry of the element. Microhardness was conducted in this research to determine the effect of alloying element on the mechanical properties of the joint.
