High-power flash butt welder is to press the two ports of the butt
welding parts with both ends of the electrode respectively. After
electrization, the forging cylinder will push the two broken ports
gradually according to the set speed. In the process of approaching
the port, the current density of the first contact part is very
high, and the metal lintel will be liquefied instantly and the
metal splash will appear after blasting, which is flash. With the
gradually close to the port, the point of contact gradually
increased, and finally the whole end face are formed numerous
liquid metal lintel, and constantly blasting, so that the end face
heating to the critical point of plastic and liquid instant on the
two end face with large forging force and pressure for a period of
time, the two end face fusion together, forming a stable joint;
