Investigation of corrosion effects on aluminum-stainless steel weld joint

In this study, effect of changing welding parameters on microstructure, mechanical properties and corrosion rate was investigated. Aluminum alloy AA6061 joined stainless steel AISI304 with same thickness of 2 mm welded using automatic MIG welding with filler metal ER5356 where arc current and arc vo...
