what is High Frequency Welding？

High frequency welding, which is a new welding process that uses the skin effect and adjacent effect generated by high-frequency current to connect steel plates with other metal materials. The emergence and maturity of high-frequency welding technology, it is a key process in the production of straight seam welded pipe (ERW). The quality of high-frequency welding directly affects the overall strength, quality grade and production speed of welded pipe products.

The purpose of the high frequency welded pipe is to weld the pipe. Straight-slot high-frequency welded steel pipe has the characteristics of relatively simple process, rapid and continuous production, and has many uses in civil construction, petrochemical, light industry and other departments. It is commonly used to transport low pressure fluids or to manufacture various types of engineered components and light industrial products.

what is High Frequency Welding Pipe Machine？

High frequency tube welding machine is a complete set of equipment for producing round steel tubes or steel pipes of various styles such as square, rectangle and oval. The raw material is strip steel. Its working process as following: Decoiling steel strip---feeding raw materials--- forming it into around pipe ---high-frequency welding---shearing weld scar---sizing it to final shape---cutting.
