Abstract - This paper describes an investigation on the effect of using two different filler metals to weld two dissimilar metals namely, stainless steel 304 and MS plates with two filler metals Including ER316L and ER70S were selected to weld the two plates Radiography and penetrant tests were performed on the welded metals to ensure the surface and internal soundness. The tensile strength of all the welded samples is found to be in between the tensile strength of the base metals. Micro-hardness test showed that weld has the highest hardness, meanwhile hardness profile of ER316L presented a sharp drop in the stainless- steel side and ER70S weld metal illustrated hardness above the two base metals with fewer variations across the weld metal.

Key Words:  TIG Welding, Stainless steel plates, Mild steel plates, Radiography and Penetration test, Micro hardness test.
