چکیده:

marine alloyed aluminum 5083 has a variety of applications due to its individual and excellent properties in welding and corrosion at marine industries at the present study this alloy has welded by using mechanized tig welding in butt joint welding and informs of two -step welding in two step welding the first step has welded without filler alloy and the second step with the filling alloy the applied filling alloy is alloyed aluminum 5183 change of frequency has made due to the evaluation of modificaitons in micro structures and mechanical properties to choose the optimized frequency for pulse tig welding with unbalanced wave.
