Production Description
Flux-cored wire is also called powder-cored wire and tubular wire. It is divided into two categories: gas-entrained and non-gas-protected. The surface of the flux-cored wire is the same as that of the solid wire, and is made of materials such as low-carbon steel or low-alloy steel with good plasticity. The manufacturing method is to first roll the steel strip into a U-shaped section shape, then fill the solder powder prepared according to the dosage into the U-shaped steel strip, roll it tightly with a rolling mill, and finally make it into different specifications by drawing cored wire.
Flux-cored welding wire is a high-performance welding wire made of powder wrapped in a thin steel strip, rolled into a tube, and then reduced or drawn. It has high production efficiency, good welding quality, beautiful process shape, low overall cost, and can be used in Robot operation, etc., is the best welding material in the application of welding automation technology. Flux-cored welding wire is a high-tech product in the welding consumables industry. It is widely used in shipbuilding, aerospace, machinery manufacturing and other industries, and has broad market prospects.

E71T-1M Flux Cored Wire FAQ
What is E71T-1M flux cored wire?
It is an all position rutile flux cored wire classified for use with an argon CO2 mixed shielding gas rather than pure CO2, depositing at the 490 MPa level on carbon steel.
Why use a mixed gas instead of CO2?
The argon mix gives a smoother arc, less spatter and a better bead profile, and it reduces fume. The cost per cubic metre is higher, which is why it tends to be used on visible or high finish work.
Can E71T-1M be used with pure CO2?
It is not qualified that way. If the job is specified against the 1M classification, the gas must be the mixed gas stated on the certificate, otherwise the procedure and the inspection documentation no longer match.
What diameters and spools are available?
0.8mm, 0.9mm, 1.0mm, 1.2mm and 1.6mm, on 5kg, 15kg or 20kg spools. Diameter choice follows plate thickness and the deposition rate the job needs.
What positions can it weld?
All positions including vertical up and overhead. The rutile slag freezes quickly enough to hold a vertical up bead, which is the main reason this family replaced basic flux core in general fabrication.
