Application of steel welding wire

Steel and aluminum welding wire are produced by larger manufacturers. Steel welding wires include TIG, MIG, SAW wires. Welding wire has its applications and is used in most industries. Welded steel wire is used for welding in construction, chemical industry, food industry, pressure mixing, automobile, oil and gas, railway, shipbuilding, nuclear power projects and other industries.

Types of steel welding wire grades

These welding wires are manufactured in various grades like ER 304,ER 304L, 307Si (18 8 Mn), ER 308, ER 308L, ER 308LSi, ER 309, ER 309L, ER 309LSi, ER 310, ER 316, ER 316L, ER 316LSi, ER 347, ER 430 & 430LNb and are manufactured in compliance with AWS A5.9/ASME SFA-5.9, EN 14343A, EN14343B, GOST and also according to the Customized chemistry as per customer requirements for specific applications. The company also supplies welding wires with EN 10204 3.1 certification. Viraj welding wires include TIG, MIG,SAW, Core wires – coil form and core wire- cut length form for electrodes manufacturing.
