Differences Between Electric Resistance Welding and 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. One of submerged arc welding (SAW)-electric welding (EFW) is a process in which metal is heated by one or several consumable
The welding method of ERW pipe and submerged arc welded pipe is significantly different. The pressure welding method without filler metal is adopted. The weld is not filled with other components, and the skin effect and the proximity effect of the high frequency current are used to instantaneously heat the edge of the plate. Differences between ERW Steel Pipe and HFW Steel PipeDuring the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond. Meanwhile with the combined pressure, the edge of the pipe billet steel

How To Weld On Used Oil Field Drill PipeIn many areas of the U.S. and Canada used oil field drill pipe is cheap and easy to find. But welding it can sometimes be tricky. The problem is that during normal use, drill pipe acquires the properties of a permanent magnet. The strong magnetic fields at the ends cause the electric welding arc to sputter, fluctuate, and leap wildly from side to side of the joint, making it difficult to get a good weld.
Due to the characteristics of ERW steel pipe welding and forming, defects that are at a certain angle to the surface of the steel pipe (hook cracks, unfused, not fully penetrated, etc.) are easy to detect. Defects perpendicular to the surface of the steel pipe (such as cold welding, gray spots, under-welding, etc.) are difficult to detect. Knowledge of erw line pipe, Sunny Steel Enterprise Ltd.Knowledge of ERW line pipe. Analysis on production process and performance of oil pipeline,which pointed out that the main reason for the lack of oil pipeline anti-rust performance and proposed oil pipeline coating process improvement, and the correct selection of a rust-proof varnish in order to achieve long-lasting anti-corrosion effect.
