Advantages

  • Compact size.
  • The control systems of the machines allows to program the unit to perform hardfacing/overlaying of several types of parts.
  • The hardfacing/overlaying process may consist of several passes with different overlaying rate, the presence of transverse oscillation, different oscillation parameters (range, speed etc.). 
  • Automation of hardfacing/overlaying process provides higher quality of the final result, excluding human factor. 
  • Availability of flat surfaces hardfacing/overlaying.
  • Minimum internal diameter of overlayed workpiece is 16 mm (½ ″) . 
  • Water-cooled welding head.
