In a welding electrode protecting machine, welding electrodes are protected against a surface treating agent on strips to be welded by applying a proper amount of electrode protecting agent onto surfaces of welding electrodes prior to or during welding operation. A seam welding machine includes a carriage (6) adapted to move in a direction orthogonal to a direction in which strips (1a, 2a) to be welded are fed, a pair of rotatable disk-like welding electrodes (8a, 8b) disposed on the carriage (6) for welding together the strips (1a, 2a) by pressing the strips (1a, 2a) to each other at surface portions thereof along which the strips are to be welded together as the carriage (6) is moved, electrode protecting agent application roll-like members (21a, 21b) for applying an electrode protecting agent (29) onto rotating surfaces of the welding electrodes (8a, 8b) while being in physical contact with the welding electrodes (8a, 8b) under pressure, the electrode protecting agent (29) which is charged from tanks (30a, 30b) by pumps (31a, 31b), and removing roll-like members (25a, 25b) disposed on the carriage for removing the electrode protecting agent (29) remaining on surface portions along which the strips (1a, 2a) to be welded were welded together at a work side relative to the welding electrodes (8a, 8b).

Seam welding machine and method for protecting welding electrodes

The seam welding machine incorporates a holding element (6) which is moves orthogonally to the feed direction of the materials (1a, 2a) to be joined, and is provided with a pair of rotatable disk-shaped welding electrodes (8a, 8b). The machine further includes an applicator system (21, 21b) for delivery of an electrode protection medium (29) onto the rotating surfaces of the welding electrodes. The applicator system is in direct contact with the welding electrodes, and is supplied with the electrode protection medium by supply units (30a, 30b; 31a, 31b). Also claimed is a method for protecting the welding electrodes of such welding machine.

PROBLEM TO BE SOLVED: To improve welding property of an electric double layer capacitor by improving a welding chip. SOLUTION: In a manufacturing method of an electric double-layer capacitor, positive poles 11 and negative poles 12 of a fixed number are alternately laminated while interposing a separator between them, and while using one part of each of positive poles and each of negative poles as lead parts 15 and 16, the overlapped parts of the same poles are respectively bonded to terminals 17 and 18 by spot welding. The welding chip 21 obtained by mounting a thermal resistance resin pipe 35 surrounding a head part 34 excepting the end of the head part is used for the welding chip 21 of the spot welding.
