Tube mills produce pipe and tube by taking a continuous strip of material and continuously roll forms it until the edges of the strip meet together at a weld station.
At this point, the welding process melts and fuses the edges of the tube together and the material exits the weld station as welded tube.
ERW tube or pipes are straight seams electric resistance welded pipe. in brief the EW pipe, which is a round pipe welded by steel plates. It uses to transport vapor and
liquid objects such as oil and natural gas. Electric resistance welding (ERW) refers to a group of welding processes such as spot welding and seam welding. faying
surfaces where heat to form the weld is born by the electrical resistance of material combined with the time and the force used to hold the materials together during
welding. In general, resistance welding methods are efficient and cause little pollution, however, their applications limited to relatively thin materials.
Electrical resistance welding
Electrical resistance welding will be welders parts formed pressed between two electrodes, and subjected to current, the resistor thermal effects generated by the
current flowing through contact with the workpiece surface and the neighboring regions to be heated to melt the plastic state, so that metal-binding method. Resistance
welding methods are mainly four types, namely, spot welding, seam welding, projection welding, butt welding.
passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material A
plate rolled to become a pipe and welded using the Electric Resistance Welding process.
