ABSTRACT:
Friction welding is preformed by linear or non-rotating orbital motion in which both parts to be joined by friction welding are moved in identical paths, out of phase to produce friction until welding temperature is attained, and then in phase, with the parts registered in alignment, during the bonding phase. Because the registered, in phase control of the mechanism is attainable with great certainty and rapidity, friction welding with a far higher precision and accuracy of alignment is attained. The high precision and accuracy of the technique permits application of friction welding to fabrication of parts, such as turbine engines, not usually made by such techniques. A preferred apparatus for practice of the invention involves an opposed pair of orbital tables (110 and 120), on which parts to be joined are mounted and fixed in place by mounts 113 and 123). The parts are aligned and registered and drives (111 and 121) then cause the parts to orbit while they are pressed together by pressure means (14), until friction heats the joint surfaces to welding temperatures.
