With the improvement of LSAW steel pipe weld quality and non-destructive flaw detection reliability, welded pipes are used more and more widely, replacing seamless steel pipes in more departments and applications. The growth rate of welded pipes is faster than seamless pipes, and the general trend of development This is. 　　

The high-frequency welding process has advantages in many aspects, and has a wide adaptability to the material of the tube blank and the specifications and dimensions of the steel tube. High-frequency welding not only improves the welding speed, but also obtains a weld with a small heat-affected zone and good penetration. 　　

In terms of quality, LSAW steel pipe has good weld quality, small internal and external burrs, high welding speed, and low power consumption. It can be widely used and promoted.
