UNG-50 WIRE WELDING MACHINE
Copper aluminum stranded wire AC resistance welding machine is a device that uses AC power for resistance welding, specifically designed for connecting copper aluminum stranded wire. This welding method is based on the principle of resistance welding, which uses the resistance between the contact surfaces of the workpiece to instantly apply low voltage and high current, causing the metal contact surfaces to heat up, melt, and fuse, thereby achieving a firm connection of the workpiece. The copper aluminum stranded wire AC resistance welding machine is suitable for connecting copper aluminum stranded wire and has the characteristics of stable welding quality, high productivity, and wide welding range.
The working principle of copper aluminum stranded wire AC resistance welding machine mainly relies on the heat generated by the contact resistance of the workpiece to heat the workpiece, causing the metal surface to melt. This welding method has the characteristics of large temperature gradient and small heat affected zone, and the weld structure and composition are close to the basic metal, making it easy to obtain equal strength and plastic welding joints. The flashing process also has a self-protection function of expelling air and reducing metal oxidation. Top forging can also remove oxides from the weld seam along with the liquid metal, reducing defects such as weld inclusions and incomplete penetration.
