Analysis of Welding Process Parameter by Taguchi Method

In this paper project was carried out to study the weldability in different steel grades by their strength. The study reveals the influence on weldability of steel by varying composition of steel by mechanical characterization. The samples were welded together by metal inert gas welding process. In large steel fabrication industries such as ship making, and train guide way, the problem of residual stresses and overall distortion has been and continues to be a major issue. In the last few decades, various research efforts have been directed at the control of optimum material selection of steels for longer service life. Yet in actual practice, large amounts of resources are still being spent in reworking welds, which in turn increases the production cost and delays work completion.
