Effects of Heat Input on Mechanical Properties of Metal Inert Gas Welded 1.6mm Thick Galvanized Steel Sheet

It is usually a lot easier and less expensive to galvanize steel before it is welded into useful products. Galvanizing afterwards is almost impossible. In this research work, Galvanized Steel was welded by using the ER 308L stainless steel filler material. This work was done to find out an alternati...
