Abstract
A method of welding bearing retainer rings comprising the steps of: assembling two annular metal retainer rings and a plurality of bearing balls, each retainer ring having a plurality of ball pockets spaced about the ring, the ball pockets of one retainer ring being aligned with the ball pockets of the other retainer ring, a bearing ball being located within each ball pocket; applying pressure to the retainer rings; and then exposing at least a portion of the area of the retainer rings between adjacent ball pockets to a coherent high-energy beam of radiation thereby fusing the retainer rings together at a plurality of locations.
