Microstructure Evaluation of Stainless Steel Welds
Journal Title: RECENT - Year 2015, Vol 16, Issue 45
Abstract
This study aims to determine the optimal parameters for cold metal transfer MAG welding of stainless steel. Starting from this perspective, the filler material of ER 316LSi full wire type and a MAG CMT - Pulse regime of welding with a low linear energy were used. Welded joints characterization was acquired by performing macro - microscopic analyses, mechanical tests (microhardness) with the purpose of lowering the thermo - mechanically affected zone. The results focus on the significant influence of the welding parameters over the weld bead geometry. The results shows that by using a proper welding speed is possible to reduce the microhardness of the weld bead and to obtain a high quality welded joint.
