HeGuang Technology is a high-tech company dedicated to develop and manufacture Seamless Flux-Cored Wires and Seamless Metal-Cored Welding Wires for shipbuilding, offshore, pipeline, bridge fabrication, structural steel fabrication and other industries. We are China’s AWS A5.29 E81T1-Ni1M-J flux cored wire manufacturer and supplier.

A5.29 E81T1-Ni1M-J is a type of flux-cored wire used for welding. The designation “A5.29” refers to the American Welding Society (AWS) specification for low-alloy steel electrodes for flux-cored arc welding. The “E” in the designation indicates that it is an electrode, and the “81” indicates the minimum tensile strength of the weld metal in ksi (thousands of pounds per square inch).

The “T1” indicates that the electrode has a rutile (titanium dioxide) flux, which provides good weld bead shape and slag release. The “Ni1M” indicates that the wire has a nominal composition of 1% nickel and 0.5% molybdenum, which provides good toughness and resistance to cracking in the weld metal. The “J” at the end indicates that the wire meets the impact toughness requirements when tested at -40°C.

Flux-cored wire is a type of welding wire that contains a flux core, which provides shielding from the atmosphere during the welding process. This allows for welding in outdoor or windy conditions, where solid wire and gas shielding may not be practical. Flux-cored wire is also often used for welding thicker materials, as it can provide deeper penetration than solid wire.
