COATING TYPE - Copper-coated

ГОСТ 2246-70 Св-08Г2С-О

ISO 14341-А -G 46 4 М21 4Si1

AWS A5.18: ER70S-6


In the production process plasma vacuum-arc wire processing provides an effective surface cleaning. As a result, the surface of treated wire obtains character silver color and high adhesive ability, that provides solid and strong coating at following coppering process. Due to quality covering and stable diameter of wire along the full length, constant wire feeding and economic consumption of copper conductive tips are provided. Precision layer winding essentially increase the lifetime of expensive semiautomatic welding machines. The possibility of working with different types of welding equipment is provided. Stable arc burning is noted which is kept for wide range of welding conditions, as well as low spatter loss, absence of overlaps and porosity in welding seam.

 Welding copper-coated wire G4Si1 is used for automatic and semi-automatic welding of carbon, and low-alloy steels for yield strength higher than G3Si1 provides. The welding wire is widely used for welding pipelines, in ship-building, in automobile and machine building, as well as in construction. The wire is applied in operation with a thin-sheet metal. In this case, the weld is formed for one pass (several passes).
