  • Friction Welder - INVT Goodrive350 Inverter
    welding is usually a method of rotating workpiece butt welding. The main parameters which need to control are rotation speed, welding time, upset pressure, friction time, friction positioning accuracy. The positioning accuracy is the key parameter of friction welder, which is related to welding quality
