Abstract
ABSTRACTIn the present work, the 4 kW CO2 laser welding process has been optimized for austenitic stainless steel (AISI 316)/ low carbon steel (AISI 1018) joint by using Taguchi based grey relational analysis. The experimental results make clear that the AISI 316/AISI 1018 laser welded joints are effectively enhanced by optimizing the input parameters. The metallurgical studies have been carried out for the optimum welded samples using an optical microscope to observe weld appearance and energy dispersive X-Ray analysis carried out to measure the nature of the matrix and chemical element distribution in the weld interface.
