The present paper aims at studying the effect of welding process parameters on the mechanical properties of stainless steel 304(18Cr-8 Ni) welded joint obtained by TIG welding. The welding parameters like welding current,Gas flow rate and filler rod diameter have varying degree of influence on the properties of the welded joint. Impact strength and hardness are determined at Welded Zone. Specimens of size 40x15x5 mm are taken for experimentation it is observed that the welding current has a significant effect on the welding parameters as compared to the filler rod diameter. The filler rod diameter also has similar effect on the welding current, but the welding current has a higher effect compared to the filler rod diameter. The present paper also involves prediction of hardness, impact strength and depth of penetration using MINITAB software. The residuals obtained from the analysis using software were find to be within limits which proves the correctness of the experimental values.
