法に関する。[Detailed Description of the Invention] [Field of Application of the Invention] Is the present invention non-consumable? It is related to the arc welding method in which welding is carried out while supplying welding current alternately to the consumable electrode and the consumable electrode, and is particularly suitable for defect-free bath welding of materials with good thermal conductivity such as copper or copper alloys without preheating. :Related to an arc welding method that can provide one method.

部は融合不良となりながらも溶は落ち不良が発生する。A method of welding by combining a consumable electrode and a non-consumable electrode and alternately supplying a welding current (hereinafter referred to as switching arc welding method) is disclosed in Japanese Patent No. 869617 and Japanese Patent Laid-Open No. 54-1
As described in No. 00950, it is used as a high-efficiency welding method because the penetration depth and welding speed are increased. This welding method is shown in Figure 1. When this switching arc welding is used to weld the circumference of a relatively thick pipe or to weld a long object, as shown in FIG. 2, the weld bead becomes poorly fused and the melt falls off.

とっては短所であった。溶は落ちを防ぐために非消耗電

というような問題が生じる。・Although the conventional welding method has the advantage of being able to achieve deep welding, it is a disadvantage when it comes to materials to be welded within a certain shape range. If the current on the non-consumable electrode side is lowered in order to prevent melt drop, poor fusion will be promoted; conversely, if the current is increased to prevent poor fusion, the melt will drop significantly.
本発明の目的は、先行する非消耗電極を機械的あるいは

熱温度域を広げ、安定した溶接部を得る方法を提供する
ことにある。An object of the present invention is to provide a method of expanding the heating temperature range of a bathed material and obtaining a stable weld by mechanically or magnetically oscillating a preceding non-consumable electrode.

することもないので溶は落ちを防ぐことができる。When the thickness of the material to be welded increases, the phenomenon shown in Figure 2 occurs because the non-consumable electrode is welded along the center of the groove. This is because the temperature of the side surface decreases as the plate thickness increases. Therefore, by shaking the preceding non-consumable electrode, the arc heat can be dispersed to the sides of the groove, which will widen the heating area and prevent fusion defects, and also prevent the arc heat from reaching the center of the groove. Since there is no need to concentrate, the melt can be prevented from falling.

FIG. 4 shows a configuration diagram of an apparatus according to an embodiment of the present invention. As a method of oscillating the arc between the non-consumable electrodes, a cyclomatic 12 was attached to the torch 6 and magnetically oscillated.

ビードとなっている。The welding conditions are: welding current of 400 A for the non-consumable electrode side, welding current of 350 A for the consumable electrode side, and welding speed of 300 wax.
/wk, and the wire feeding speed was set to 6 m7/-. Further, the frequency of the magnetic oscillation was set to 30H2. 5 and 6 show the state in which the arc of the non-consumable electrode is swung from side to side by magnetic oscillation, and by oscillating, the side surfaces of the groove are also sufficiently heated. Figure 7 shows the welding results.1. It is a good bead with no poor fusion or melting.

This method has the effect of providing a high-quality welded part with no defects such as poor fusion or melt drop-off when using materials with good thermal conductivity.
