The insufficient place of traditional friction welding method is, cannot carry out quite to the component that cannot rotate solder. Body may have 18m so long, solder to make friction welding receives a law to be able to be used at conduit, development goes a kind of new remodel. The main distinction that this kind of new remodel and traditional friction welding accept a method is: The process is fashioned in rigid cirque in, use different fill data. Solder cirque is placed to be between two pipe, rotate below axial pressure solder cirque, the attrition power that can produce a need and to it relevant quantity of heat. When two parts component is contacted each other, solder in what rotate the temperature that cirque and two attrition between pipe can make contact an area is elevatory, till reach the temperature of mutual forge welding till. In this instant, solder the whirl of annulus stops very quickly, axial pressure lifts subsequently final forge welding pressure. Forge welding pressure but force of explosion of have the aid of (fluid is moved or pneumatic) will bring to bear on.
