TUU 28.7-31749248-006-2003 EN 14700/ T Fe14 DIN 8555/ MF 10-GF-65-G (suspended)

Welding process: О – open arc	Wire diameter, mm	Recommended shielding gases and fluxes
О	1,6-3,2	-

General characteristics

It is designed for open-arc cladding of parts operating under conditions of joint effect of abrasive wear and moderate impact loads.

Application

Typical applications are as follows: cladding of equipment for feeding of mineral raw materials, exca vator bucket teeth, scraper working edges, wear-resistant plates, protective surfaces of cones and cups, dredge pumps, mixer blades and gratings for sieving machines etc.

Weldability

The Formation of the weld bead	good
Separation of Slag	good, solid crust no
Deposition Rate, kg/h	6-13
Addiction Weld metal Cracking	increased
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 58-65

Technological features

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