General characteristics

It is designed for automatic open-arc metal deposition of wear-resistant layer on parts experiencing heavy impact loads.

Application

Typical applications are as follows: deposition of hard-facing layers on high-manganese steel parts operated under high specific pressure and impact loads, cladding of hammers and cones of crushers, armor plates, hammers of mills for grinding coal, restoration of excavator bucket teeth and teeth of coal grinding machine segments, crusher cones and jaws, repair hard-facing of railroad frogs.

Weldability

The Formation of the weld bead	good
Separation of Slag	good
Deposition Rate, kg/h	6-15
Addiction Weld metal Cracking	moderate
Consumption per 1 kg of wire Weld metal, kg	1.1-1.15
Weld metal Hardness (HRC for 3rd-4th layer, unless otherwise stated)	after surfacing HB 200-HB 240 after work hardening 40-45

Technological features

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