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.

Frequently asked questions
Does high-frequency welding use filler metal?
No. The two edges of the formed strip are heated by the high-frequency current and then forged together by the squeeze rolls, so the joint is made from the strip material itself rather than from an added filler.
What do the skin effect and the adjacent effect do in this process?
They are the two properties of high-frequency current the process relies on. The skin effect concentrates the current near the surface of the strip rather than through its full section, and the adjacent effect pulls that current toward the nearby strip edges. The result is that the edges reach welding temperature while the rest of the tube stays relatively cool.
Which machines on this site use high-frequency welding?
Most of the tube mills and pipe lines on this site use a high-frequency welder as the welding station, including the straight-seam lines, the ERW line, the HG series and the high-frequency stainless steel pipe roll forming machine.
