Abstract
Welding wire is made with the use of wire rod composed of steels Sv-08G2S, Sv-08G1S, and SG-1, 2, 3. A new technology that has been developed to obtain this product provides for mechanical scale removal, dry drawing of the wire rod to an intermediate diameter of 1.7–2.2 mm, then — without an intermediate heat treatment — wet drying combined with electrochemical copper-plating of the wire surface. The diameter of the wire is 1.6—0.8 (0.6) mm. The advantages of the new technology for making welding wire are obvious: a reduction in production cost due to the elimination of pickling and heat treatment for the rod; an improvement in the environmental situation at the manufacturing plant.
