definition:

High frequency Resistance Welding ( ERW) , is unlike ordinary welded pipe

Welding process, Welding seam is composed of steel belt ontology of parent

metal melting and mechanical strength than the general Welding control.

production:

ERW steel pipe is made by high frequency welding machine to certain

specifications of strip steel coil into circular tube and straight seam welded steel

pipe.

The shape of the ERW straight welded pipe can be round, straight seam

welded pipe pipe, also can be square, square rectangular tubes or aliens, special

- shaped steel tube, it depends on the sizing rolling after welding.

Resistance

welding with high production efficiency, low cost, save material, easy automation,

etc, therefore widely used in aviation, aerospace, energy, electronics, automobile,

light industry and so on various industry sectors, is one of the important welding

process.
