    In a device for resistance welding with two opposite electrodes (10, 11) which can be moved towards one another under the action of force and are each held by current-carrying electrode carriers (13, 14), an electromagnetic force (Fe2) acts between the electrode carriers (13, 14) as a result of the welding current. According to the invention, this electromagnetic force is utilized for increasing the electrode force (F) by the movement of the electrode carriers (13, 14) away from one another being converted into a movement of the electrodes (10, 11) towards one another as a result of the electromagnetic force (Fe2). Since the electromagnetic force only acts when the welding current flows, an excessive electrode force which can damage pressure-sensitive components to be welded before the welding operation is avoided, and follow-up of the electrodes and their reliable contact with the components to be welded is guaranteed during the welding operation. …<IMAGE>…

    Phie.1
    The invention relates to welding and can be used in the development of equipment for resistance spot welding of parts made of materials with high conductivity.
    The purpose of the invention is to improve the quality of the welded joint.
    PA figure 1 shows a schematic structural diagram of the device with an electrode holder C-shaped; figure 2 is the same, side view; FIG. 3 shows an embodiment of the device with a gantry electrode holder; figure 4 is the same, side view.
    A device for resistance spot welding contains upper 1 and lower 2 electrode holders mounted for movement in direction with one another, the upper electrode holder being rigidly fixed from the drive unit 3, on which the guide columns 4 and the pusher 5 are mounted. Between the electrode holders 1 and 2, an adjustable spring 6 is mounted. The lower electrode holder 2 is made straight-line and the upper electrode 7 is mounted on its pile. The upper electrode holder 1 covers the lower electrode holder on the side. On the upper electrode holder 1, the lower electrode 8 is installed coaxially with the upper one.
    The top electrode holder is C-shaped and covers the bottom bottom electrode holder on one side. To increase the rigidity of the electrode holder and to improve the positioning accuracy of the parts to be welded, it is possible to make the upper electrode holder 1 gantry, the coverage of the lower electrode holder 2 is made on both sides. Electrode holders 1 and 2 are connected to the current-carrying levels 9 and 10, respectively. Position 11 marked magnetic field lines.
    The device for contact point slarks works as follows.
    Weldable parts (not shown) are placed between electrodes 7 and 8, create the necessary clamping forces and turn on the welding current, which flows along the electrode holders in opposite directions. An electromagnetic field arises around the electrode holders, which repels the electric holders from one another
    Fg. The TTD by the action of the electromagnetic force Fg ensures constant contact of the electrodes with the parts being welded and their subsequent movement during the welding process. With the flow of welding current, besides the mechanical force on the electrodes, an electromagnetic force also acts in the same direction.
    The design of the device described allows for welding parts with high conductivity, such as silver plates, to provide
    “J” is pre-clamped with a relatively small force and securely fixed without damaging the contacting surfaces with the point contact. During the passage of the welding current, the electromagnetic movement of the electrodes and their constant contact with the parts to be welded is ensured due to the electromagnetic force. As a result, the quality of the welded joint improves.
