Inspite of a number of types of welding processes, Tig (Tungsten Inert Gas) welding has been widely used in the industries because of its ease in usage and also it shields the fusion zone from the atmospheric contaminants during welding and helps in improving the strength of the weld bead. The present work aims at joining of two similar metal pieces of AISI SS316 of 100x20x5mm each using TIG welding. Experimentations were carried using Vickers hardness testing machine, universal testing machine for finding tensile strength, microstructures of all the specimens at fusion zone and HAZ were found under 200x of magnification. An orthogonal array L2 is formed to find out the maximum tensile stress, hardness of the weldment at a load of 600KN.
