EN ISO 14341-A-G 42 4 M21 3Si1

Welding wire with copper-plated surface G3Sі1

the welding wire is used for welding (Surfacing) of products, parts and structures made of carbon and low-alloy steels in a flat, vertical and overhead positions
welding can be carried out both in gas mixtures and in pure CO,
* to obtain a high-quality joint scale, rust and various oxide coatings must be removed
« for multi-pass welding, the surface of the previous bead must be
cleaned of slag.

Special properties

the wire undergoes plasma vacuum-arc treatment while being manufactured which ensures the cleanliness of the surface from non-metallic inclusions and the application of a high-quality copper coating, which improves the welding and technological properties of the wire
the use of G3Si1 welding wire allows you to improve the quality of finished
parts and products by forming a clean and reliable welded joint.

Copper-coated welding wire of G3Si1 grade is designed for automatic and semi-automatic welding of carbon and low-alloy steels with a yield strength of 420 N/mm2. Welding wire is widely used for pipeline welding, in the shipbuilding industry, automotive and mechanical engineering, as well as in constructionTh.e wire is used for working with both thin sheet metal and multi-pass welding.
