An investigated of butt joint between aluminum alloy A5052 and stainless steel SS400 by using MIG welding method

The purpose of this research indicates the experimental results of the Metal Inert Gas (MIG) welding process of butt joint between A5052 alloys and SS400 steel using ER4043 filler metal. The mechanical properties of the joints were investigate. The results of the analysis shows that the intermetallic compound layer appeared at interface between steel and welding seam with their width increasing from 3.106 μm to 4.929μm and the maximum micro-hardness at IMCs layer reached 850HV.
