Introduction to Welded Pipe Manufacturing - The Process

Jul 26, 2018High Frequency Welding. Initially ERW manufacturing process used low frequency A.C. current to heat the edges. This low frequency process was used from the 1920s until 1970. In 1970, the low frequency process was superseded by a high frequency ERW process which produced a OPTIMISING TECHNOLOGY FOR PRODUCTION OF HIGH High frequency tube welding is one of the most forgiving industrial processes nowadays, and it is possible to produce acceptable tubing for most purposes. High frequency welding is a form of electrical resistance welding (ERW). A voltage is applied (HF contact) or induced (HF induction) across the edges of the open tube just priorPeople also askWhat is high frequency welding?What is high frequency welding?The high frequency welding (HFW) is mainly used in ordinary or thin wall steel pipe. It includes contact welding and induction welding. Direct current welding is generally used for small caliber steel tubes.Differences between ERW Steel Pipe and HFW Steel Pipe

Welded vs. seamless steel pipe American Piping Products

Welded 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.What is the difference between HFW and ERW?High-frequency welding (HFW) is a solid resistance heat energy. The use of high-frequency current welding resistance heat generated in the workpiece so that the workpiece is heated to melt the welding area or near the surface of the plastic state, then applied (or not applied) forging force and achieve a combination of metals.What is the difference between seamless pipe and erw pipe high frequency schedule 40 carbon erwElectric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its high frequency schedule 40 carbon erw
