PROCESS AND MACHINE FOR FRICTION WELDING OF CIRCULAR SECTION SEMIPRODUCTS

摘要

the invention refers to a process and a machine for welding rods and pipes by friction.the process consists in fixing sudarii between respective heads and heads subjected to insert a piece of material which has added a spin move.while the play of additive material rotates on the heads sudarii semi-finished products subject to exert axial forces on the downforce of additive material.process for making machine is made up of a buzz saw on some devices that can move another grip moving holding device and training in a spin moveof the addition.
