Laser and micro plasma arc welding of thin sheet inconel 718 and aisi 316l stainless steel at similar and dissimilar combinations

Abstract

Fusion welding of Inconel 718 and AISI 316L stainless steel at similar and dissimilar combinations are challenging due to the formation of micro fissure or solidification crack that often adversely affects the mechanical properties of the welded joint In the present work this takes as an opportunity to address all the issues aiming at a successful weld of 700 206 188 m thick sheet using both micro plasma and laser welding processes High transients and gradients affects the solidification behavior o...
