  5. electric resistance welding pipe Electric resistance welded (ERW) pipe | MS Pipe Industries

    Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then 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.

    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.

  7. electric resistance welding pipe Electric resistance welding at a glance - Sunny Steel

    Several 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 common–all 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.

  8. electric resistance welding pipe Difference between Seamless & ERW Stainless Steel pipe

    Electric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its ...
