Current passes between the two edges of the steel to heat the steel to a point at which the edges are able to connect together to form a bond using the actual welding process. ERW is normally used to transport liquid, such as petrol and gas, playing a significant role in the world line pipe trSee more on octgproductsdifferentce between ERW pipe and EFW pipedifferentce in between ERW pipe and EFW pipeline A53 SCH40 ERW PIPELINE vs EFW PIPELINE EFW are considerably different than ERW Electric Resistance Welded Pipe.
