Development of Advanced Electric Resistance Welding

erated by passing a high frequency current through the edges. At the seam of the ERW butt weld (hereinafter, seam), the welding beads on the pipe inside and outside surfaces are removed by online, full-length grinding, followed by seam heat treatment to improve the weld microstructure (Fig. 1). After ERW linepipes are cut to the specified length,Differences Between ERW Steel Pipe and HFW Steel Pipe 100*100 high frequency welded erw steelHigh-frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHz.

Differences Between Electric Resistance Welding and 100*100 high frequency welded erw steel

High-quality steel pipes require heat treatment on the weld line or off-line to refine the microstructure of the weld zone. The weld of the high-quality ERW welded pipe can reach the same level of toughness as the base metal, which cannot be achieved by the submerged arc welding process. EFW is the abbreviation of electric fusion welding.Differences between ERW Steel Pipe and HFW Steel PipeThe 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. So, ERW steel pipe includes HFW steel pipe.ERW Pipe | Electric Resistance WeldedElectric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches. However, the manufacturing process is fast so it is ideal for large production runs of small (<= 24 in.) diameter sections.
