Copper Coated Welding Wire with Fast Melting Rate

Copper coated welding wire is the main product of welding wire. It is used very extensively, because of its good welding performance and higher efficiency in welding. And it is suitable for pure CO2 and argon and CO2 mixed gas as the shielded gas. Therefore, there are many factories that manufacture copper welding wire in the world.

The production process of copper coated welding wire is shown below: firstly, its raw material is wire rod. Secondly, the wire rod goes through two wire drawing process. Thirdly, the step is the copper plating line. Next, the wire is spooled by the wire winding machine. Then the welding wire is inspected and packed in different forms. Delivering the goods to customers is the last step.

Two baskets copper welding wire, one leans against another.
Basket-packaged copper welding wire has beautiful appearance.
Copper welding wire winded on a black plastic spool orderly.
Spool-packaged copper welding wire is cheaper for extensive application.
Copper welding wire wrapped into a round shape with four strings bind.
Coil-packaged copper welding wire has the most simple package for seen directly.
Drums wrapped into plastic film, placed on a wooden pallet, top wooden board, with strings fixed them into a whole.
Copper welding wire put into drums makes its transportation safer.

Copper coated welding wire is mainly used to weld copper and copper alloys, such as vessels, vehicles, bridges, construction or engineering machinery, pressure vessels, agricultural equipment, pipe of high speed welding, steam and hot water boilers and so on.
