What is the difference between HFW and ERW?

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.Resistance by the current flowing through the thermal effect of resistance welding a workpiece contacting surface of the surrounding area is heated to What is a Welded Steel Pipe? About Welded or ERW Steel Electric Resistance Welded (ERW) and High Frequency Induction (HFI) Welded Pipe,originally this type of pipe,which contains a solid phase butt weld,was produced using resistance heating to make the longitudinal weld (ERW).But most pipe mills now use high frequency induction heating (HFI) for better control and consistency.What is a Welded Steel Pipe?
