It includes contact welding and induction welding. DC welding is usually used for small diameter steel pipes. Generally, HFW is one of ERW production methods, which uses high-frequency welding technology. Therefore, ERW steel pipe includes HFW steel pipe.
High frequency welding (HFW) is mainly used for ordinary or thin-walled steel pipes. It includes contact welding and induction welding. DC welding is usually used for small diameter steel pipes. Generally, HFW is one of ERW production methods, which uses high-frequency welding technology. Therefore, ERW steel pipe includes HFW steel pipe. Differences between ERW Steel Pipe and HFW Steel PipeHigh frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.

High frequency welding effect on steel pipe. In the process of high-frequency welding of steel pipes, the control of the welding process and process parameters, the position of the induction coil and the location of the resistance have a great influence on the welding quality of the steel pipe welding.

Tianjin Yuantai Derun pipe manufacturing group Co. Ltd. was formally established, marking that the production of high-frequency welded black, galvanized square pipe, spiral welded pipe, pipe logistics and pipe trade as one of the large-scale joint enterprise Yuantai Derun group was formally established, the group registered capital is USD 20 Welded Steel Pipes for Sales from leading Welded Steel Welded steel pipe are common pipe type with technology and craft of welding. Normally welded steel pipe may divide into two categories such as electric resistance welded steel tube (ERW) and Spiral welded steel pipe. According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency electric resistance welded pipe, gas welded pipe, furnace welded
While welded steel pipes date back to Scottish engineer William Murdock's invention of the coal-burning lamp system made from barrels of muskets to transport coal gas in 1815, seamless pipes weren't introduced until the late 1880s for transporting gasoline and oil. technology let engineers use high-frequency induction mending machines for steel pipe making machine/tube mill_High-frequency Welding 110KW.
