Welding wire polished uncoated

Purpose

Wire of grades 4Si1 and 3Si1 is used in shipbuilding, in car building, in boiler building, in assembly work, in construction for welding metal structures, in the automotive industry, in agricultural engineering.

Diameter

0,8 — 2,0 мм

Steel grades

4Si1, 3Si1

It is used for automatic and mechanized welding and surfacing of carbon and low-alloy structural steels in a protective gas environment (DSTU EN ISO 14175): carbon dioxide (DSTU 4817), argon (DSTU GOST 10157) and a mixture of carbon dioxide and argon, submerged arc welding (DSTU EN ISO 14174).
