Effect of parameter interactions on hybrid tig-mag arc welding process

This study is an attempt to study Hybrid TIG-MAG arc welding process basis interactions of the process controlling parameters with reference to the depth of weld penetration and the transverse tensile strength of the welded joint as the process outcome. Experiments are conducted for the outcome using an indigenous hybrid arc welding fixture and the results are studied by superimposing the response surfaces to arrive at the common optimum of the interacting process parameters for the 12mm thick mild steel plates. The convergence obtained is further validated through interlinked experimental iterations.
