PARAMETRIC OPTIMISATION OF TIGW ON STAINLESS STEEL BY TAGUCHI METHOD

The main objective of the book is to reveal with manufacturing better quality product at low cost and increase productivity. TIG welding is most vital and common operation use for joining of two similar or dissimilar parts with heating the material or applying the pressure by using the filler material for increasing productivity with less and cost constrain. The TIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. The purpose of this study is to propose a method decide near optimal setting of the welding process parameters in TIG welding. This project shows the influence of welding current, arc voltage and gas flow rate on strength of stainless steel and mild steel material during welding. A taguchi orthogonal array, signal to noise ratio and analysis of variance are employed to investigate the welding characteristics of dissimilar joint and optimize the welding parameters.
