E71T-11 Gasless
AWS A5.20 Class E71T-11
E71T-11 is a self-shielding, all-position flux cored wire for single or multi-pass welds on mild or galvanized steel. This wire is a general purpose wire designed for light fabrication and is good for single pass on thinner gauged material or limited multi-pass on thicker sections. Noted for its smoother arc, full slag coverage, low spatter and great bead appearance, the 71T-11 is a great choice where a secondary shielding gas is not practical.
Applications:
Use 71T-11 for general fabrication, prefab construction, tank and railcar repair and light structural work. Multi-pass welds should be used on plate thickness up to 3/8”(9.5mm). Also a great choice for field repair of fences, parts and machinery.
