TIG Welding Wire

TIG welding wire, supplied as cut-length filler rods, is used with the gas tungsten arc (GTAW) process wherever weld quality, appearance and control matter more than speed. Typical Oman and GCC applications include root passes on pressure piping, thin-wall stainless pipework, heat exchangers, boiler tubing and critical repair welds. For carbon steel, AWS A5.18 ER70S-2, ER70S-3 and ER70S-6 rods are common, while ER80S-B2 and ER90S-B3 cover chrome-moly steels, and ER308L, ER316L and ER309L serve stainless applications.

Rod selection should match the base metal chemistry, the welding procedure and the service environment. Use argon shielding, and back-purge stainless and duplex roots to avoid oxidation. Rod diameters from 1.6 to 3.2 mm are usual, with 1.0 mm for thin sections, and rods must be kept clean and identified by their stamped or tagged classification.

Seven Star LLC supplies TIG rods from LongTeng and other manufacturers, with technical support in Muscat. Compare with solid welding wire for MIG production work, filter by base material for stainless, chrome-moly and duplex alloy duties, and see the matching TIG welding machines and TIG torches. The broader range sits under welding consumables.
