Sell Un Series AC Resistance Butt Welding Machine

The parts to be butt welded are pneumatically and hydraulically controlled to provide an even flash contact at the contact edges. Initially the power is turned on and progressively increased to remove oxidants and residues. The end surfaces of the parts to be welded are heated to plastic stage through a regulated power supply. Upset forging force is then applied to make the end surfaces to get flushed and welded. The machine is designed to provide the high welding strength to the welded component. There is no false joint, residue and air bubble in the point of welding. The machine is widely used in the butt welding of handles of kitchen utensils such as knife, fork, spoon and spatula, as well as the welding of hardware products such as round pipes, square pipes, round steel, flat iron, bicycle wheel rims, motor wheel rims, etc.
