  • Electric resistance welded (ERW) pipe | ASTM A234 butt ...

    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.
