Abstract

Welding dissimilar metals and alloys is essential to emerging new technologies in manufacturing industries. This process is difficult because of the formation of intermetallic layers and the variations in the chemical and mechanical properties in the weld region. This paper aimed to characterize fully and partially penetrated dissimilar metal weld joints. The welding experiments were conducted on 0.5 mm-thick dissimilar weld joints for the investigation of the effects of the process parameters on the weld joints. Variations in chemical composition, oxide formation, imperfections and mechanical properties were analyzed. Results revealed that the weld joint characteristics notably deviated from the base metal properties in terms of hardness, strength, chemical composition, oxide formation and other constituents of the weld pool region. This study offers insight into the effects of process parameters and the necessary changes in weld composition for the improvement of welds joints.
