Electric resistance welded (ERW) pipe is made from steel
coil and the weld seam runs parallel to the pipe.ERW
pipe is manufactured by cold forming a flat steel strip into a rounded tube and
passing it through a series of forming rollers to obtain a longitudinal seam.
The two edges are then simultaneously heated with a high frequency current and
squeezed together to produce a bond. The longitudinal ERW seam does not require
filler metal while impurities in the heat affected zone are extruded during the
welding process.
A
few advantages to note with ERW pipe:
- There are no fusion metals used during the manufacturing
process. This means that the pipe is extremely strong and durable.
- The weld seam cannot be seen or felt. This is a major
difference when looking at the double submerged arc welding process, which
creates an obvious welded bead that might need to be eliminated.
- With the advances in high-frequency electric currents for welding, the process is far easier and safer.
