Abstract: Roll-seam resistance welding of containers (esp. for food and drink) made of very thin sheet metal, is claimed. The seam is produced as a butt joint without use of wire. The appts. has a first rotatably driven roll head (5) with two electrodes (2,3) and an electrode cleaning device of continuous or discontinuous action, and a second roll head (8) without electrodes. By using a feed mechanism, the container shells (1) with abutting joint edges are fed to the roll heads (5,8).

Abstract: The method includes rolling-seam welding of sheet metal lap joints with a predetermined nominal welding pressure. The method is effected by the fact that the welding force is reduced at the start of the welding operation. The rolled-seam resistance welding machine incorporates means for short-duration reduction of the force acting on the welding rolls.

Abstract: A roller head (10) for a resistance seam welding machine has an internally located sliding contact current transmission device (24) between stator 12) and rotor (14) and is composed of a pair of circular ring-shaped discs (26, 26') which extend radially between rotor and stator, are fastened to the rotor on their outer circumferences, carry axial sliding contact rings (32,32') on their inner circumferences, and are flexible designed in their intermediate parts (28,28') between inner and outer circumferences. These sliding contact discs (26,26') are composed of a copper mesh, to which the axial sliding contact rings (32,32') are fastened. Thin-walled metallic diaphragms can also be used instead of the copper mesh. The roller head (10) can transmit high welding currents. As a result of the flexible design of the sliding contact discs (26,26') the contact presssure, which is created by a stack of plate springs (40), remains constant even with external mechanical influences.

Abstract: An oscillating electrode wheel head (210) for a resistance seam welding machine is described, which has a sliding contact current transfer device (224) between a stator (220b) and a rotor (223), which device consists of a disc (226) in the form of a circular ring which extends radially between the rotor and the stator, is attached on its outer circumference to the stator, supports an axial sliding contact ring (232) on its inner circumference and is constructed in a flexible manner in its web part (228) located between the inner and outer circumference. The sliding contact disc (226) consists of a copper mesh to which the axial sliding contact ring (232) is attached. The sliding contact current transfer device (224) in the form of the disc (226) having a flexible web part (228) replaces the current transfer device, in the form of liquid metal, which is otherwise normal in oscillating electrode wheel heads. … …
