    An improved arc-welding process and apparatus for producing welded seams by means of band or flat strip electrodes. The apparatus of the invention uses at least two band or flat strip electrodes which overlap at least partially. The aformentioned flat strip electrodes are then welded by means of arc-welding in a common welding bath.

    one
    The invention relates to the welding industry and can be used in the surfacing of wide surfaces in the manufacture of new and repair of worn parts in machinostroy- 5
    SRI.
    The known method of arc wide-layer surfacing, in which the electrode feed is performed in such a way that the axis of the weld bead is located perpendicular to the plane of the tape. In this case, the width of the weld bead is almost equal to the width of the tape electrode 1.
    The disadvantage of this method is that it is necessary to vary the width of the ribbon electrode, depending on the need to obtain a certain width of the weld bead.
    The closest to the described 20 invention to the technical essence and the achieved result is a method of arc welding with simultaneous supply of at least two tape electrodes to the total welding bath 25 2.
    The disadvantage of this method is that the electrodes are supplied congruently, which leads to an increase in Dimensional sizes; 1 electrode tape for 30
    2
    I get a certain width of the weld bead.
    The aim of the invention is to improve the reflow performance with minimal penetration.
    This goal is achieved by the fact that tape-type electrodes are positioned (perpendicular to the direction of welding with a degree of overlap within 16100% of the width of the electrodes. In addition, at a 100% degree of overlap, the tape-type electrodes are positioned with a gap of 2-10 mm between the wide sides in welding.
    FIG. 1, 2 and 3 shows the arrangement of tape electrodes with different magnitude of overlap.
    Electrodes of any shape, the width of which is much greater than their thickness, can be used as tape electrodes. The ratio of the width to the thickness of the tape electrodes lies in the range between 360: 1 and 3: 1. The most commonly used tape electrodes are 60 X 0.5 mm in size, which corresponds to a ratio of width to thickness of 120: 1.
    It is possible to perform welding with strip electrodes of different composition.
    Example 1. Conducted surfacing two tape electrodes of austenitic class under the flux on the undoped structural steel (C 0.08%, Si 0.026%, Mp 0.45%). The size of the electrodes is 60 X 0.5 mm, the overlap is 10 mm, the welding speed is 15 cm / min, the welding current is 990 A, the voltage is 30 V.
    A satisfactory deposition was obtained (bead width 110 mm, height 4.6 mm). Roller smooth and smooth. In the eon overlap, the rise is not formed.
    Example 2.-The deposition was carried out using three ribbon electrodes of 60 x 0.5 mm in size, whose composition is the same as in example 1. Welding mode: DCB 1250-1350 A, Ucg 30 V, speed 13 cm / min. Electrode Offsets Shown in FIG. one.

    Claims (2)
    [1]
    1. The method of arc welding with simultaneous filing of at least two
    two tape electrodes into a common weld pool, characterized in that, in order to increase the reflow performance with minimum penetration, the tape electrodes are arranged perpendicular to the welding direction with a degree of overlap within 16-100% of the electrode width.
    [2]
    2. The method according to claim 1, is also distinguished by the fact that at a 100% degree of overlapping, the tape electrodes are positioned with a gap of 2-10 mm between the wide sides in the welding direction.
