Investigating the Effect of Process Parameters in Manual Metal Arc Welding for Joining Dissimilar Metals

Prajakta G Ahire, U. S. Patil

Abstract: In this research work, two dissimilar metals are welded to get optimum weld deposition rate with high weld strength by optimizing input process parameters. In manual metal arc welding input process parameters are taken as welding current, welding speed, root gap, electrode angle. Dissimilar metals are low carbon steel and stainless steel 304L. Taguchi L9 array is used for conducting the experiment and results obtained through experiments are used for deciding levels for optimization.
