The advantage of this processing technology of ERW (ERW STEEL PIPE) is that there is a heat treatment process after welding, which eliminates the residual stress in the weld and heat-affected zone, refines the crystal grains, and has a small heat-affected zone of the weld and fast heating speed, which can greatly improve the welding speed and Welding seam quality, and can be used as blanks without pickling, shot blasting and trimming strip steel, while welding alloy steel, high alloy steel and non-ferrous metal pipes, greatly reducing the unit power consumption, with a set of welding equipment can produce Kind of ERW. 

Therefore, the ERW unit needs to fully utilize and expand its own advantages in order to improve product quality and develop new products.
