Process and machine for friction welding
Abstract
Abstract THIS DISCLOSURE RELATES TO THE PROCESS OF FRICTION WELDING AND, SPECIFICALLY, TO A METHOD AND APPARATUS WHEREBY THE MECHANICAL WORK TRANSFERED TO THE PARTS TO BE WELDED IS CONTROLLED IN ACCORDANCE WITH A PRE-ESTABLISHED PROGRAM OF ENERGY VERSUS TIME. THE ENERGY BEING SUPPLIED TO THE WORK PIECES IS DETERMINED BY MEASURING THE ANGULAR ROTATION AND THE RESISTANT TORQUE BETWEEN THE TWO PARTS RUBBING ONE AGAINST THE OTHER, OR BY MEASURING THE TEMPERATURE OF THE PARTS. THE MEASURED VALUES ARE COMPARED TO THE REFERENCE VALUES AND THE AXIAL FORCE BETWEEN THE PARTS BEING WELDED IS CONTROLLED SO AS TO MAINTAIN THE ERROR BETWEEN THE REFERENCE AND THE ENERGY INPUT AS CLOSE TO ZERO AS POSSIBLE.
