A robot system RK757 for MIG/MAG surfacing of rail ends.


RK757 intends For multilayer welding on the end of the rail with length 1 000 ... 3 110 mm the thick layer of stainless steel up to 22 mm.

A method of surfacing: CMT arc welding process by solid wire with diameter 1.2 mm.

A rail axis is tilted relatively to the vertical axis on the angle 10/20/30 degree.

Surfacing is carried out with a positive formation of the side weld surface with concomitant water cooled forming devices.
