  • Publication number: 20130092662
    Abstract: Joining surfaces (2a, 2b) of a pair of conductive joining members (1a, 1b) to be joined to each other are caused to face each other, and while one of the joining members (1a, 1b) is slid relative to the other of the joining members (1a, 1b), a current is passed from one of the joining members (1a, 1b) to the other of the joining members (1a, 1b) so as to cause resistance heating. Abrasion, plastic flow, and material diffusion therefore occur in high surface-pressure sections of the joining surfaces (2a, 2b), and the joining surfaces (2a, 2b) are joined together while current concentration locations are varied from moment to moment.

The process consists of holding the drum on a cradle via an indexing table, the cradle being able to pivot and vertically movable so as to present different regions of its outer surface parallel to the plane of orbital motion of the blade. The blade is held in the orbital motion device by a clamping device. The inner surface of the drum is braced by supports carried by a core fixed to the cradle. The drum comprises a series of protrusions which have a blade-shaped cross section. These protrusions form faying surfaces for the blades. The blades have a plate to ensure they are satisfactorily clamped by the clamping device.

  • Patent number: 8278583
    Abstract: In order to evaluate the welding current for the resistance seam welding of an overlap seam of container bodies, a welding with changing welding current intensity is carried out for a container body of the production series, resulting in a changing welding of the seam, ranging from the welding with a too high temperature to the welding with a too low temperature. The electric energy for this welding is determined several times during this welding and/or the temperature of the weld seam is determined several times and the welding current intensity is determined at which the welding of the individual container body is too cold and the welding current intensity at which the welding is too hot. This determination is based on the determined electric energy values and/or on the determined temperature values and based on this determination a preferred range for the welding current intensity within these limits of too hot and too cold is determined.
