General characteristics

It is designed for automatic and semi-automatic open-arc metal deposition of wear-resistant layer on parts.

Application

Typical applications are as follows: hard-facing of railroad frogs, blade parts of wheel blasting machines, jaw plates for crushers, bats of hammer mills, reconstruction of dimensions and filling-up patching of Hadfield steel casting flaws, buckets of excavators and other parts experiencing heavy impact loads.

Weldability

The Formation of the weld bead	good
Separation of Slag	good
Deposition Rate, kg/h	4-12
Addiction Weld metal Cracking	moderate
Consumption per 1 kg of wire Weld metal, kg	1.05-1.15
Weld metal Hardness (HRC for 3rd-4th layer, unless otherwise stated)	after surfacing HB 160-HB 260 after work hardening 40-50

Technological features

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