A REVIEW OF DESTRUCTIVE AND NON DESTRUCTIVE TESTING OF ALUMINUM AND ALUMINUM ALLOY PLATE OF TIG WELDING METHODS

This paper reviews is deals with, the welded quality of aluminum and aluminum alloy plate by TIG welding method. TIG welding method is one of the most used and popular methods to weld aluminum. Aluminum has unique properties ductile, non-magnetic, light weight, weld ability and also it has corrosion resistance in nature. Input parameters were varied according to the experimental design. The accuracy and quality of welded joints largely depends upon the type of inert gas, welding speed and type of power supply. The mechanical properties of weld joint also varying based on the parameters. The mechanical property like YS and UTS varies by pulsed and non-pulsed current by different frequencies. It has wide application in industry fields namely marine, aircraft, heat exchanger, automobile, oil refineries etc.
