Metal Spool K300 Welding Wire

The Welding Wire ER70S-6 is 500MPa level carbon steel wire. It take CO2 or 80%Ar + 20%CO2 gas shielded arc welding. The welding

spatter is small, and it has beautiful appearance, high cladding efficiency and small weld metal porosity sensibility. The welding

technology of all positions is good.

For Co2 Copper coated Solid Welding Wire, the copper-plating factors are as follows:

1: Increase conductivity. Copper plating on the surface of the silicon-manganese alloy wire is beneficial to improve the conductivity.

2: Good effect of reducing wire feeding resistance. The welding wire passes through the wire feeding hose, and the copper coating can reduce the resistance of the welding wire in the loose wire hose, ensuring smooth and stable wire feeding.

3: Rust resistance. The copper plating layer has anti-rust ability, which can prevent the welding wire from rusting and affect the welding quality; it can also ensure smooth welding wire feeding.

Production Process:

Wire release: after the prepared raw materials are released, they are mechanically peeled off;

Rust removal: The raw materials that have been peeled off are subjected to abrasive belt treatment (during the treatment process, dust removal is carried out with a cloth bag), to remove the oxide skin on the surface of the welding wire and the remaining impurities on the surface of the welding wire, and obtain the raw material of the welding wire for derusting;

Wire drawing: the wire drawing process is performed on the raw materials of the welding wire after derusting to obtain the semi-finished product of the welding wire, and then the semi-finished product is subjected to wire-drawing and fine-drawing treatment;

High-speed copper plating: activate and copper-plate the semi-finished products that have been drawn;

Polishing: Polish and take up the copper-plated welding wire;

Finally, the copper-plated welding wire is unwound, layered, packaged and put into storage.

This process uses the abrasive belt to derust and clean the surface of the welding wire raw material. Compared with the existing technology, the amount of acid is reduced, and the welding wire does not need to be cleaned with alkali, so that the impurities on the surface of the welding wire can be effectively removed by the abrasive belt derusting, and the acid is reduced. The amount of lye is low, energy saving and environmental protection.
