FABRICATION AND ANALYSIS OF SS316-CuAl BIMETALLIC WALL MADE BY METAL INERT GAS (MIG) BASED WIRE ARC ADDITVE MANUFACTURING

Abstract: Wire arc additive manufacturing is one of the emerging and rapidly growing technology which is gradually employed in manufacturing real time products without much of material wastage especially where expensive materials are utilised like aerospace industry. Since the metal is deposited by means of welding layer by layer heating and cooling of layers occur repeatedly. This paper focuses on investigation suitability of WAAM process in producing bimetals consisting of one ferrous (SS 316L) and one non-ferrous metal (CuAl-A2). Initially a SS wall is made by layer-by-layer deposition. It is the followed depositing aluminium bronze on the lateral side of the wall by tilting the welding torch. The developed bimetallic wall is then detached from the substrate is subjected to testing and the results are discussed.
