PROCESS FOR CLOSING A HOLE IN A METAL PART BY MEANS OF FRICTION WELDING, USE OF A METAL BAR AND A BEARING BRACKET TO CARRY OUT THE PROCESS

摘要

the invention relates to a method of plugging, by friction welding.a hole (2), extending generally along one axis (5), a piece of metal(1).a clearance space is not available on the axis (5) of the hole (2).do at least one obstacle (6) on the axis (5), in which a barmetal(3) extending generally along a line (4) is set in rotationtheaxis (4) and is inserted into the hole (2) to be welded by friction.themethod of the invention is characterized by the fact that the axis of the bar (4)(3)inclined relative to the axis (5) of the hole (2) at an angle (a) is not zero, in order to avoidthe barrier (6).thus, in the process of the invention, it is possible to achievethe holes (2) are difficult to access through proper axis (4) of the wheel(3).
