Study of Micro Structure, Grain Size and Hardness of MIG Welded Dissimilar Joint of AISI 304 and AISI 310 Steel
Abstract
Welding of dissimilar metals has posed a major challenge due to differences in thermal, mechanical, and chemical properties of the materials to be joined under a common welding condition. In the present work, AISI 304 and AISI 310 sheets of steel are joined using the
MIG welding process. Welding Current, filler wire feed rate, and edge included angle are considered as welding input parameters. Grain size and hardness are considered as output responses. For three factors and three levels, a total of 15 experiments are performed as per Box–Benhken Design of Response Surface Method. The welding parameters were optimized using Response optimizer for minimum grain size and maximum hardness of weld joint.
