EFW pipe

Electric fusion welding (EFW) pipe refers to an electro beam welding, the use of high speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, welding forms. It is mainly used to weld dissimilar steel welding sheet or steel sheet with high power density, metal weldment can be  heated rapidly to high temperatures, then melt. So small performance can impact on the joints, the joints almost have no distortion. But it has a requirement on special welding room because weldig uses X-ray.
