method for closing, by means of reibschweissen, a hole in a metal part, use of a metallic bar, and a wellenlagers for implementation of the procedure

摘要

P the invention relates to a method of closure, by friction welding, with a hole (2), extending substantially along an axis (5), of a metal part (1), in which a metal bar (3), extending globally along an axis (4), is rotated about its axis (4) and is introduced into the hole (2), in order to be welded by friction. The process of the invention is characterized by the fact that the axis (4) of the bar (3) is inclined with respect to the axis (5) of the hole (2) by an angle (α) not nul.ainsi, by virtue of the process of the invention, it is possible to reach the holes (2) which are difficult of access by suitably orienting the axis (4) of the bar (3). / p
