Solid Welding Wire

Solid welding wire is the continuous bare or copper-coated wire used for gas-shielded MIG/MAG (GMAW) welding. Seven Star LLC supplies solid MIG wire in Oman from LongTeng, Ador Welding, Hyundai Welding and Lincoln Electric. The listing runs from everyday carbon steel grades such as ER70S-6, through high-strength ER80S-G to ER110S-G, to a chrome-moly ER90S-B3, a duplex ER2209 and a nickel alloy 625 wire. Every product title includes the AWS classification, so the wire can be checked directly against the welding procedure.

Solid MIG wire grades in this category

Carbon steel wires are classified under AWS A5.18. ER70S-3, ER70S-4 and ER70S-6 differ mainly in silicon and manganese content. The higher deoxidizer level of ER70S-6 copes better with mill scale and light rust and gives a more fluid pool, which is why it is the default in structural and general fabrication. A copper-free ER70S-6 is listed as well.

Low-alloy wires fall under AWS A5.28. The G suffix means the chemistry is agreed between maker and buyer, so two ER80S-G wires are not necessarily alike and the datasheets have to be compared. ER90S-B3 matches 2.25Cr-1Mo steels. ER2209 is the standard filler for 22Cr duplex stainless steel, and ERNiCrMo-3 is used on alloy 625, for weld overlay and for dissimilar joints.

Choosing diameter, shielding gas and packaging

Diameter follows plate thickness and transfer mode: smaller wires for sheet and positional short-circuit work, larger ones for spray or pulsed transfer on plate. Carbon steel wire runs on CO2 or argon-CO2 mixtures, while stainless, duplex and nickel wires need the argon-rich gases named on the wire datasheet. Packaging deserves the same attention as grade. Spools suit manual stations, and bulk drums cut changeovers on robots and mechanized seams.
