    The invention relates to equipment for contact roller welding, in particular, contact wire welding machines, and can be used for welding parts from sheet materials having narrow weldable flanges made with lead or other coatings. The purpose of the invention is to improve the quality of welding. A contact wire welding machine includes a contact roller 1 with a V-shaped groove 3 on the generatrix of the cylindrical surface 4, 5 and wire 2. The wire 2 is installed in roller 1 with the ability to interact with the groove 3 by a central protrusion 6. Part 7 of wire 2, opposite part of the wire with a protrusion 6, is made convex or V-shaped. The wire 2 is made with two longitudinal protrusions 8 and 9 in the transitional areas between the part 6 with a protrusion and the reverse side 7 of the wire to rely on the cylindrical surfaces 4, 5 of roller 1. In section, the contact surface profiles of the wire 2 and roller 1 repeat each other. throughout. The length of the contact line of the longitudinal projections 8, 9 on the wire 2 with the roller 1 is 30-50% of the length of the contact line of the V-shaped profiles of the roller 1 and the groove. In the case of the front side 7 of the wire 2 convex in section, the longitudinal protrusions 8, 9 are made with a common radius R of curvature with the front side 7 of the contact wire. The presence of protrusions 8, 9 on the wire allows it to increase its contact surface with the roller electrode 1. The wire profile eliminates the rotation of the wire in the groove 3 in the welding zone and its overheating, and also allows welding with minor current loads on the wire in the contact zone with detail. In the heat-affected zone after welding when using wire, there are no gaps between the sheets. 2 hp f-ly, 2 ill.

    The invention relates to equipment for contact roller welding, in particular, contact wire welding machines, and can be used to weld parts of sheet materials having narrow weldable flanges made with lead and other coatings, etc. .
    The purpose of the invention is to improve the quality of welding.
    FIG. 1 shows a roller electrode of a roller welding machine and a contact wire interacting with it; in fig. 2 is a section of a welded joint obtained using the electrode wire described.
     The contact welding machine contains roller electrodes and a non-contact wire. The upper roller electrode 1 and the lower roller electrode of the welding machine are made similar to each other.
    Contact wire 2 has a wide profile with a large radius R of the surface in contact with the product (fsh.1). The roller electrode is made with a circumferential guide groove 3 having a V-shaped cross section. Adjacent to the guide groove 3, the forming surfaces 4 and 5 of the roller are cylindrical. The angle about (Fig. 1) of the guide of the groove 3 is equal to the angle of the contact wire 2 introduced into the guide groove 3 of part 6 and is 120. The contact wire is made with a convex part that is welded to the workpiece, while the back part 6 facing the guide groove 3 is made with a longitudinal central V-shaped
    SPEAKING.
    In the transition section between the part 7 facing the workpiece to be welded and the part 6 facing the roller electrode 1, the contact wire 2 is provided with molded protrusions 8 and 9, which serve to support the contact wire 2 on the forming surfaces 4 and 5 of the roller electrode from both sides of the guide groove 3.

    The wire 2 is made of a round billet (for this purpose, a tool of the corresponding configuration provided for the roller welding machine or outside of it is used. If the surface of the wire part 6 is taken as 100%, the wire 2 contacts the roller electrode 1 within the guide groove 3 , the contact surface between the contact wire 2 and the roller electrode 1 is 130-150 °, since the contact wire 2 is additionally in contact with the roller electrode 1 by the back side of the projections 8. The presence the protuberances in the transition between the front and back sides of the roller prevents the wire from turning in the groove of roller 1. This rotation can cause a decrease in the quality of welding. Reliability of preventing such a rotation is maximum if the lower limit of the increase of the contact surface of the electrode-wire projections 8 and 9) in the order of 30%. Exceeding the upper limit of 50% is impractical because it leads to an increase in the loss of wire material (the wire does not participate in welding, i.e. not consumed).
    The reverse part 6 of the contact wire 2 located in the guide groove 3 is angled in the opposite direction of the projections 8 and 9, i.e. repeats the profile of the surface 1 of the electrode (figure 1). In addition, all of the wire part 7, including sections 10 and 11. the protrusions 8 and 9 are convex and have a total radius of curvature R, which is chosen so that the outer longitudinal edges 12 and 13 of the protrusions 8 and 9 contact the surface of the workpiece to be welded during welding. At the same time, the outer longitudinal edges 12 and 13 of the protrusions have a distance of 0.1-1 mm from the surface of the workpiece to be welded. It should be noted that in FIG. 1 contact wire 2 is shown in cross section in strongly
    on a larger scale. Actually, for example, size A is about 395 mm, size B is about 2.6 mm, and size H is about 1.3 mm.
    FIG. Figure 1 shows only the convex cross-sectional shape of the portion 7 of the contact wire 2 facing the product, however, its portion 7 may also have a V-shaped cross-section. The front part 7 of the contact wire can also be provided with grooves formed in the longitudinal direction.
    FIG. 2 shows a section of a welded joint made on the fuel tank using the contact wire 2 according to FIG. 1. At point b, the longitudinal edge 13 of the contact wire 2 does not come into contact with the sheet, as a result of which a soft transition is obtained and undesirable ones are prevented from being hollow from the edges of the wire, and at the point with the weld core there is no tear, near the core of the weld point.
    The test results on the strength of the welded joint obtained using the proposed machine showed a significant increase in fatigue strength (it lies at least 500% higher than the required minimum value).
    A contact wire roller welding machine can most effectively be used for welding, for example, fuel tanks made with electrolytic or hot surface lining and with narrow welding flanges.
    Due to the protrusions molded on both longitudinal sides of the wire, the described contact wire has a large contact surface with a roller electrode. The profile of the contact wire, which extends beyond the guide groove, is very thin and cannot be deformed laterally when subjected to transverse forces even in the case of softening during welding, so that the effect of buckling in the welding zone is not observed. Due to the larger contact surface, the described contact wire is well cooled. In addition, the specific current load in the transition zone between the roller electrode and the wire is much lower. Due to the wide reference surface of the contact wire, the sheets to be welded are pressed together in the immediate vicinity of the weld point core. In this way, loose contact between the sheets is prevented.
    5 with the core of the welding point and thus the lateral rupture of the core of the weld point during the operation of products.
