Corrosion Resistance of Synergistic Welding Process of Aluminium Alloy 6061 T6 in Sea Water

This work involves studying corrosion resistance of AA 6061T6 butt welded joints using Two different welding processes, tungsten inert gas (TIG) and a solid state welding process known as friction stir welding, TIG welding process carried out by using Rolled sheet of thickness6mm to obtain a weld jo...
