Welding process: G – in shielding gas	Wire diameter, mm	Recommended shielding gases and fluxes
G	1,2-3,6

General characteristics

It is designed for gas-shielded mechanized 1.2-3.6 mm arc welding of metal structures made of low-carbon and low-alloyed steels, rolled steel sheets of increased strength, including those exploited at low temperatures. It can be used for filling-up patching of flaws in the castings of carbon and alloyed structural steels.

Application

Typical objects of the wire application are as follows: building metal structures, transport machine building, parts and components of road-building and construction machinery, elements of load-lifting facilities etc.

Welding technology

The welding is performed at reverse of welding current- DC(+).
