The effect of frequency in welding thick-walled HFI pipes

In both conductive and inductive HF welding, the principle is based on the fact that a current flows on the pipe surface and the band edges (Fig. 1). This highfrequency current flows on the surface of the pipe via the edges of the strip to the welding point at which the melted strip edges are forced together and welded.Welded vs. Seamless Steel Pipe What to Know. May 30, 2019During the process, a high-frequency electrical current passes between the edges. Its this current that causes the edges to melt and eventually fuse together. One of the main advantages of welded steel pipes is that no fusion metals are used and that the weld seam is unable to be felt or seen.Welded vs. seamless steel pipe American Piping ProductsWelded pipe manufacturing techniques have improved over the years. Perhaps the most important advancement has been the switch to high-frequency electric currents for welding. Prior to the 1970s, low-frequency current was used. Weld seams produced from low-frequency ERW were more prone to corrosion and seam failure.
