PURPOSE AND FIELD OF APPLICATION
Welding copper-coated wire SD-G3 is used for automatic and semi-automatic welding of carbon and low-alloy steels with yield strength of up to 420 N/mm2. 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 thick-sheet metal. In this case the weld is formed for one pass (several passes).
APPLICATION CONDITIONS
Welding copper-coated wire is used for welding (surfacing) of products, parts and structures, made of carbon and low-alloy steels, in flat, vertical and overhead positions. It is possible to perform welding both in gas mixtures, and also in pure CO2. To produce the quality weld, the scale, rust and different oxide coatings should be removed. During the multi-pass welding the surface of the previous bead should be cleaned from a slag.
SPECIAL PROPERTIES
Due to the absence of non-metallic inclusions, the welding-technological properties of deposited material are improved after the plasma vacuum-arc treatment. The application of copper-plated welding wire SD-G3 allows increasing the quality of ready parts and products by forming a clean and reliable weld.
Welding wire SD-G3 guarantees:
– easy arc ignition due to optimal coating and perfect geometric parameters;
– minimum spattering during welding in CO2 and absence of spatters during welding in gas mixture М21;
– almost absence of a slag film on weld;
– high stability of arc burning.
