General characteristics

It is designed for automatic submerged arc metal deposition of wear-resistant layer on parts operated under conditions of metal-to-metal friction in corrosive environment.

Application

Typical applications are as follows: cladding of rods of hydraulic G!S timbering for salt and coal mines, hydraulic press plungers and crankshafts.
