Tensile Behavior of Laser Beam Welded (Lbw) Similar and Dissimilar Metals

Welding of dissimilar metals has attracted the attention of researches worldwide because it has many advantages and challenges. Many welding techniques have been used by researchers for joining the dissimilar metal combination. Laser Beam Welding (LBW) is one of the non-conventional and non-traditional methods to join both similar and dissimilar metals. In this study, the dissimilar metals such as Stainless Steel 304 and Stainless Steel 316L are joined using Laser Beam Welding (LBW). The tensile tests of similar and dissimilar metals were conducted after joining using LBW as per the ASTM standards. An Analytical Study also was conducted to investigate the stress contours and deformations of welded specimens using ANSYS. Dissimilar metals after joined using LBW showed higher tensile strength when compared with similar metals. A good agreement was found between experimental and analytical results.
