High frequency resistance welding (HFW) steel pipe is a kind of resistance welding steel pipe without filling metal. Its external surface is smooth, so it is not easy to observe the welding seam position from the external surface, and the size accuracy is high, so it is easy to be coated with anti-corrosion.The pipe making process has a great influence on the quality and specification of HFW steel pipe.Due to the limitation of pipe making technology,HFW steel pipe's outer diameter and wall thickness are generally not too large.

The quality of welding seam is an important factor affecting the quality of HFw steel pipe. At present, there have been many HFw pipe bursts and leakage accidents in China, most of which are caused by the failure of welding seam position, resulting in great economic losses.
