Welding is the process of joining two or more similar or dissimilar metals by applying heat and pressure. Among all
other welding processes TIG welding is regularly used for joining the components in Nuclear Reactors because it produces high
weld strength and involves less cleaning process post welding. In this study SS 304 and SS 316L are joined by using pulsed TIG
welding process with SS 316LER as filler wire. Parameters like Welding Current, Gas Flow Rate and Root Gap are varying.
These parameters are assessed by means of Taguchi L4 Orthogonal array.
