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.
