AWS A5.20 Class E 71T-GS
USA E71T-GS is self-shielding flux cored wire for single pass all-position welds on mild steels used for field construction, erection and repair. It is often used for fabrication of mild steel sheet metal where secondary shielding gas is not practical. USA E71T-GS is used to weld mild steels and it finds acceptance for use in fabrication and repair welds on thin mild steel and galvanized steel. USA E71T- GS is noted for its smooth, stable arc, full slag coverage, low spatter generation, ease of slag removal and excellent weld bead appearance. It has relatively light penetration and tolerates rust, dirt, and oil on the work piece. The weld deposit resembles that of E6011 Electrodes
USA E71T-GS is used extensively in maintenance for the fabrication, erection and repair of mild steel sheetmetal and is used in applications where secondary shield gas is not practical. The weld deposits are smooth and have light penetration helping to eliminate burn-throughs. The use of USA E71T-GS should be limited to non-structural applications only. USA E71T-GS is noted for its smooth arc and low spatter.
