The way of mechanised welding in mixed is created protective gases by an alternating current. The main lack welding by a direct current chaotic moving arch in backlash between welded plates under by action of magnetic influence. This phenomenon prevents welding in a narrow (slot-hole) backlash, root, angular seams and other kinds of connection on installations of pipe lines and other designs. The way will allow to overcome this lack will expand area of application of the mechanized welding in protective gases. Product Description popup.authors popup.nrat_date 2020-04-02 Close
