Global Electric Resistance Welded (ERW) Pipes and Tubes Manufacturer

Global Electric Resistance Welded (ERW) Pipes and Tubes Manufacturer Electric Resistance Welding is the process of welding metal pieces or parts permanently together. By heating the metal parts with current electricity, the joints' metal melts and sticks to each other. The electric resistance welding process applies to manufacturing steel pipes and assembling automobile body parts. There are four resistance welding methods: seam welding, butt welding, spot welding, and projection welding.

If you are looking for basic knowledge before purchasing electric-resistant welded tubes and pipes, you have come to the right place. Here some pointers that will clear your view on the matter of electric resistance welded pipes and tubes.

The process of ERW During the whole electric resistance welding process, two electrodes made of copper are utilised to apply current and pressure. The electrodes are shaped like discs and rotate when materials pass through between them. This helps the electrodes stay in touch with the material for long continuous welding.

Manufacturing the pipes The pipe construction process uses steel sheets that are then cold-formed into a cylindrical shape— heating the steel by supplying current between the edges to a point where the edges are bound together by force without welding materials.

Advantages of installing electric resistance welded pipes and tubes The pipes are robust and durable as there is no metal fusion in the initial manufacturing stage.

Compared to other welding processes, the electric resistance welding process is more efficient as the weld seam is not present. This process is faster and more comfortable because the welding process requires an electric current of very high frequency. The metallurgical part is simple because it is enclosed by plastic rings when the molten core formation occurs. Time taken for heating is hugely less and concentrated, resulting in less area on which the heat is affected. Stress and deformities are also negligible. Filter metals like electrodes and welding wires are not required.

Other welding materials, such as hydrogen, oxygen, and acetylene, are also not needed. This leads to the process being cost-efficient. The electric resistance welding process is an easy operation.

Automation and mechanisation are easy to achieve. The electric resistance welding process has a very high productivity rate and doesn't emit any harmful gases or noise. The process is compatible with mass production.

There are two types of electric resistance welding, rotary contact wheel and high-frequency. As the name suggests, the welding-generated heat is the outcome of the steel's resistance to the electric current's flow. The pressure generated from the rolls' compression transforms it into its final shape, producing electric-resistant welded tubes and pipes.
