Embodiment Construction

[0029] FIG. 1 shows the end of an electrode 1 for resistance spot welding which faces the workpiece to be welded during the welding process. Concentric to the longitudinal axis of the electrode 1 , a cover 2 is provided, which is pushed onto the end of the electrode 1 .

[0030]Electrode 1 has an inlet device 4 for feeding a coolant in the direction of arrow 5 . This coolant is used here to cool the electrode 1, in particular the electrode tip, during the welding process. Cooling water is usually used as coolant. The supply device introduces coolant via a cooling channel 6 into the end region 7 of the electrode 1 . There the coolant flushes around the end region 7 and deflects in the direction of the arrow 8 and flows back via return channels not shown, ie flows backwards from the electrode tip.

[0031] In this embodiment, the supply device is designed such that a cold medium can be supplied for cleaning welding spatter adhering to the electrodes. This is achieved in a ti...

Abstract

The invention relates to a method for cleaning an electrode (1) used in resistance point welding, particular a cap (2) which can be placed on the electrode. According to the invention, the electrode (1) and / or the cap (2) are impinged upon with a cold medium. The temperature difference between the cold medium and the functional parts to be cleaned is greater than 80 Kelvin and the temperature of the functional parts is above room temperature. The invention also relates to an electrode (1) for resistance point welding, in addition to a cap (2) which can be placed on the electrode (1) . According to the invention, the electrode (1) and / or the cap (2) has a feed direction for supplying the cold medium.

Description

technical field [0001] The invention relates to a method for cleaning an electrode used in resistance spot welding according to the preamble of claim 1 , a method for cleaning an electrode used in resistance spot welding according to the preamble of claim 8 Electrodes, a cover for fitting onto an electrode according to the preamble of claim 9 , and a device for resistance spot welding according to claim 12 . Background technique [0002] Such electrodes or electrode caps for use in resistance spot welding are known, for example, from US 5,387,774A. [0003] Welding spatter generated during welding deposits in and on functional parts of the welding device, for example on electrodes of a resistance spot welding device or on nozzles of an arc welding device, and must be removed at any time. [0004] Mechanical and contactless methods are known for this. [0005] In mechanical cleaning, a rotating tool is usually used, for example a bell cutter, which is adapted to the shape o...
