Laser Beam Welding technique is applied to conduct experiments on joining of dissimilar metals, AISI 4130 and AISI 310 steels so as to study the influence of process parameters on mechanical properties of joints. Taguchi L25 Orthogonal Array is selected to join 2mm thick dissimilar steels by varying Laser Power, Welding Speed, Beam Incident Angle, Focal Point Position and Focal Length. Output results of Ultimate Tensile Strength (UTS) and Impact Strength (IS) are measured. ANOVA is carried out to obtain the levels of influence of process parameters and statistical evolution of the results. TOPSIS optimization is applied to transmogrify a multi-criteria optimization problem into a single-criterion problem, so as to obtain optimal combination of process parameters of Laser Beam Welding. Then UTS and IS are maximised. Results have revealed that the proposed method is appropriate for solving multi-criteria optimization of process parameters.Keywords
Laser Beam Welding, Ultimate Tensile Strength, Impact Strength, Analysis of Variance, TOPSIS.

Friction stir welding (FSW), a solid-State welding technique, is being extensively used in similar as well as dissimilar joining of Al Mg, Cu, Ti, and their alloys. In the present study, the two aluminum plates are joined by adding Magnesium particles of 60 mesh were the welding zone before the welding was carried. The variable parameters that affect much are taken as input parameters. They are tool rotation speed, tool traverse speed and three different joint profiles like (straight, inclined, semicircle) and with and without magnesium the paper discuss the influence of hardness, tensile strength, impact strength. The work material conducted AA6061 T6. Taguchi method based on L18 so used as DOE.Keywords
