High-frequency electric resistance welding: An overview

HF ERW: A History. Electric resistance welding was modified and improved in the 1950s by Thermatool's Wallace Rudd. Rudd developed high-frequency welding and, in doing so, solved some of the inherent process limitations of DC welding and low-frequency welding, such as Difference between ERW, SSAW, LSAW - Sunny SteelDifference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).China Customized High Frequency Tile Carbon Steel / Iron , high frequency erw carbon steel pipes tubesDescription: High frequency welding is used in the production of steel welded pipes.
