Dec 01, 2007 · This article focuses on the techniques required from welder's perspective, so that he or she can make the transition from TIG welding carbon steel to TIG welding alloy metals such as stainless steel, duplex stainless steel, Inconel® (Ni-Cr, Ni-Cr-Mo and Ni-Cr-Co-Mo alloys), Monel® (Ni-Cu and Cu-Ni alloys) and pipe from related alloys. Analysis of High Frequency Welding Process - nan-steelThe high-frequency welding of steel pipes uses the skin effect and proximity effect of alternating current. After the steel (strip) is rolled and formed, a circular tube blank with a broken section is formed, which rotates in the tube near the center of the induction coil.

High Frequency Welder Solid State HF Welder Company profile_High-frequency Welding Carbon Steel Company profile-High-frequency Welding Carbon Steel Tube Mill Making,Carbon Steel Straight Seam Tube Mill Tube Making Machine-Hebei Tengtian Welded Pipe Equipment Manufacturing Co., Ltd. is a legally registered limited company specializing in the production and sale of metallurgical equipment and high-frequency welded pipe equipment,It is a professional manufacturer of pipe mill and cold roll 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.
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. In general, HFW is one of ERW production methods, it adopts the high frequency welding process.

The Welding Advantages of High Frequency Welded pipeThe welding advantages of high frequency welded pipe. The advanced nature of high frequency welded pipe:The development history of welded steel pipe technology has progressed with the competition of seamless steel pipe products. To replace seamless steel pipes with welded steel pipes in certain fields, the key lies in the high product quality and lower production costs.
The high-frequency welding for carbon steel welded pipe production has been 40 years of history. Having a large power supply power, high-frequency welding of different material, diameter and wall thickness of a steel pipe can reach a higher welding speed (highest ratio TIG welding speed is more than l0 times higher). carbon steel pipe making machine_High-frequency Welding High frequency straight seam welded pipe production line is the specifications of the steel belt feeding unit, through the roll bring curled up into a tube billet steel, and then use the high frequency of proximity effect and skin effect make the strip edge instantaneous heating to welding temperature, and under the action of squeezing roller complete welding, then through water cooling Carbon steel pipe / tube mill - slitterline.netcarbon steel pipe mill , carbon steel tube mill.
