Abstract: Process for welding a weld-in part (3) in a weld point comprising a metal plate and a metal covering lying thereon with two tools of which one is formed by a welding head (11) and the other by a drill (12) for preparing the weld point by a drilling process. The drill (12) attached to a revolving device (7) initially in one operating position, by means of a lifting motor (4) which can be moved in a controlled manner between a return position and a machining end-position and vice versa, performs the process at least until the metal plate (17) is drilled (machining end-position) in preparation of the weld point. By pivoting of the revolving device (7), a welding head arranged on the revolving device (7) and equipped with the weld-in part (13) is then brought into an operating position above the prepared weld point to perform welding, meanwhile the drill (12) is coupled to the lifting motor (4) when the welding head (11) is coupled to the lifting motor (4) when the drill (12) is uncoupled to perform welding on completion of the drilling process. Drill (12) and the welding head (11) are each set aside in their return position on a rest shoulder after pivoting of the revolving device, the welding head (11) being equipped with a weld-in part (13) in the rest position and the revolving device (7) pivoting the drill or the welding head into the respective operating position from the rest position.

Abstract: The invention relates to a method of removing punch rivets (4,14,23), which are set into a workpiece (12,13) and have a male die end (15) for driving the punch rivet (7,14) and an opposite female die end (16) which penetrates the workpiece (12,13). A pin (18) is placed with its front end (19) onto the male die end (15) so as substantially to cover the latter and, with a simultaneous supply of energy through the pin (18), heats the contact area between pin (18) and male die end (15) up to a fusion temperature in the contact area, whereupon after cooling of the contact area the pin (18) is retracted counter to the pressure of an abutment supported on the workpiece (12,13) and carries along the punch rivet (7,14) which is thereby withdrawn from the workpiece (12,13).

Abstract: The invention relates to a process and a device for removing punch rivets (23) set in a workpiece (12,13), which are tubular and axisymmetric in design. Upon setting of the punch rivet (23) a punched-out piece (21) remaining therein is removed by a tool (18) and thereafter a threaded mandrel (20) is screwed into the punch rivet (23) with simultaneous formation of a substantially continuous distinctive thread. Upon its subsequent withdrawal counter to the pressure of an abutment (22) resting on the workpiece (12,13) the threaded mandrel (20) withdraws the punch rivet (23) from the workpiece (12,13).
