Optimisation of influence of Tig Welding parameters on mechanical properties of aluminum 6061 alloy:A Review

ABSTRACT Aluminum alloys are used for many industrial applications due to their light weight and corrosion resistivity. Amongst all aluminum alloys 6061 has excellent properties, which makes it useful in aeroscope industry, aviation, marine industry and defence. Tig welding is one of the precise method which is used to weld aluminum alloys. From the literature survey it has found that Welding current, Welding voltage, Welding speed and the gas flow rate are the main input parameters which influence the mechanical properties of aluminum 6061 alloy. An attempt has made to find the conditions like how these welding parameters will set, optimization method and choice of filler rod under which aluminum 6061 plate will give optimum mechanical properties.
