Which is an advantage of using ERW pipe?

In the ERW process, high-frequency electrical current is passed between the edges, causing them to melt and fuse together. An advantage of ERW pipe is that no fusion metals are used and the weld seam cannot be seen or felt.See all results for this questionWhat's the difference between ERW and EfW welding?High-quality steel pipes require heat treatment on the weld line or off-line to refine the microstructure of the weld zone. 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.See all results for this questionWhat is the difference between HFW and ERW?Jan 20, 2016 · Electrical resistance weld (ERW) is the combination of applying pressure to the workpiece through the electrode, a method using welding current through a resistor in thermal contact with the joint surface and the surrounding area generated.

ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc.See all results for this questionHeat-treating line pipe weld seams - The FabricatorDuring high-frequency welding, the outer and inner sides of the pipe wall experience the highest temperatures. This creates a heat-affected zone (HAZ) with a characteristic hour-glass shape. The heat also changes the tensile properties of the HAZ, reducing its toughness (its ability to absorb an impact without rupturing).
