Electric Resistance Welded(ERW)and High Frequency

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. Electric resistance welded (ERW) pipe ASTM A234 butt In 1970, the low frequency process was superseded by a high frequency ERW process which produced a higher quality weld. Over time, the welds of low frequency ERW pipe was found to be susceptible to selective seam corrosion, hook cracks, and inadequate bonding of the seams, so low frequency ERW is no longer used to manufacture pipe.
