Advantages

  • The machine is completed with forced cooling welding head and bended water-cooled burner for welding of fillet welds. 
  • The machine allows hardfacing / overlaying of cylindrical workpieces with length up to 1250 mm (49"). 
  • The control system of the machine is implemented on the basis of industrial controller, which allows the operator to set the parameters of welding (range of oscillations, velocity of the oscillations, number of the faceplate revolutions, length of overlaying etc.) on the touch screen of control panel and to perform welding process in automatic mode.
  • Electrode oscillating mechanism provides greater performance of the hardfacing / overlaying process. 
  • The machine allows to perform hardfacing / overlaying of cylindrical surfaces and welding of girth seams with automatic filling of the cutting edge. 
  • The machine can be equipped with an additional (second) welding head to provide its greater performance.
