Welding process: О – open arc G – in shielding gas	Wire diameter, mm	Recommended shielding gases and fluxes
О	1,6-2,4	-
G	1,6-3,2	М21 (18% СО₂ + 82% Ar)

General characteristics

It is designed for open-arc or gas-shielded arc metal deposition of strengthening layers as applied to impact-and-abrasive and gas-abrasive wear.

Application

Typical applications are as follows: hard-facing of blades for smoke exhausters, operating parts of construction machines and road construction equipment such as bucket teeth for bucket-wheel excavators, bucket noses, cutting edges of excavator buckets, blades for graders and scrapers, shovels for ground-displacing machines as well as hopper cone for blast furnaces.

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	1.1-1.2
Weld metal Hardness (HRC for 3rd-4th layer, unless otherwise stated)	after surfacing 60-65

Technological features

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