Welding seam is in longitudinal. During 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.
This method is called resistance welding because it is the resistance between the contact surfaces of the metals being welded that generates the heat to fuse them together. Resistance is the opposition that a substance offers to the flow of electric current. The less resistance a metal has, the less heat is generated when current passes through it.Guide to Spot Welding | Westermans BlogTom, Resistance spot welding is an electric welding process where the heat required to melt and to join the pieces of metal together is generated by the electrical resistance between the two sheets. Typically, this is done by applying high pressure between two electrodes, one on either side of the sheet, and then an extremely high current is electric resistance welding studded pipeElectric resistance welding at a glance - The FabricatorSeveral electric resistance welding (ERW) processes are available for tube and pipe production. While each process has different characteristics, all ERW processes have one thing in commonall of them produce a forged weld. A forged weld is created by applying a combination of heat and pressure, or forging force, to the weld zone.
Electric resistance welding can be divided into two kinds:resistance welding and induction welding.ERW pipe is cold formed into a cylindrical shape rather than hot formed. An electric current rather than a flame is used to heat the edges of the strip for the fusion weld. Revolving copper discs serve as electrodes and raise the temperature to about 2600°F for effective welding.Electric Resistance Welding Pipe - EZ Steel Industrial Co electric resistance welding studded pipeChina Electric Resistance Welding Pipe catalog of ERW Round Galvanized Steel Pipe, API / ASTM ERW Welded Mild Steel Black Round Pipe for Furnitures and Construction provided by China manufacturer - EZ Steel Industrial Co., Ltd., page1.Electric Resistance Welded Pipe, ERW Steel Pipes, Electric electric resistance welding studded pipeHigh-frequency electric resistance welding (ERW) steel pipe production, internal weld surface treatments are generally incomplete curettage (left weld reinforcement) and complete curettage (scraping will form the inner surface of the groove) in two ways, and the results were not ideal, will affect the overall performance of the steel pipe.
