General characteristics

It is designed for automatic as well as semi-automatic gas-shielded arc or submerged arc cladding of parts operating under conditions of metal-to-metal friction and adhesive wear environment as well as for deposition of buffer layers prior strengthening cladding.

Application

Typical applications are as follows: cladding of wheels for running gear, shafts and spindles, gearwheels, pulleys, tractor wheels, restoration cladding of roller necks for continuous casting machines, bandages and supporting rollers etc.

Technological features

It is recommended for metal arc deposition at direct current of reverse polarity- DC(+).

Properties of the weld metal

The deposited metal is ductile enough and can be easily processed mechanically.
