Welding process: G – in shielding gas	Wire diameter, mm	Recommended shielding gases and fluxes
G	1,2–2,4

General characteristics

It is designed for gas-shielded mechanized arc welding of metal structures made of low-carbon and low-alloyed steels, general purpose rolled steel sheets of increased strength with carbon content being less than 0.25 3 (wt.).

Application

It is used for welding building metal structures, metal structures in transport machine building and when welding technological tanks, vessels and reservoirs as well as technological pipelines, components and parts of road-building machine and construction machinery etc.

Welding technology

The welding is performed at reverse polarity of welding current - DC(+) in carbon dioxide shielding gas.
