Microstructural Transformations in Dissimilar Welds between Austenitic Stainless Steel and Ferritic Stainless Steel

This research studies the metallurgical transformations taking place the SMAW welding of AISI 316L austenitic stainless steel with AISI 430 ferritic stainless steel. To perform the study were used two different electrodes, AWS E309L austenitic and AWS E2209-16 duplex stainless steels 3.2 mm diameter. The joints were made with a single-pass welding including current and welding speed variations; the low values were 49 A and 2,4 mm.s–1 and the high values were 107 A and 4,3 mm.s–1. This study evaluated the influence of the type of electrode and the welding parameters on the microstructural e...
