Differences between ERW and HFW Steel Pipe
ERW welding process refers the heat generated by the resistance to current flow that pass through the jointed metals While HFW welding process is not the same case with the high-frequency process since it’s only a section of the steel metals is heated by the induction of electric coil. High-frequency is generated by either AC or DC current. The electric current that pass through the entire conductor is at 50/60 Hz in ERW Welding Process While in HFW Welding Process it ranges to frequency rages of 100-600 KHz
