1と鋼板2との側面を溶接する方法が一般的であった。An ultra-thin metal plate generally called a foil having a thickness of about 10 μm to 100 μm or a metal net having a fine mesh, for example, a stainless steel foil and a metal plate having a thickness of about 0.2 mm to 3.0 m, such as a steel plate, are used. In the case of welding, as shown in FIG. 5, after the foil 1 and the steel plate 2 which are the objects to be welded are cut into a required shape, the screens of the foil 1 and the steel plate 2 are uniformly adjusted. The foil 1 and the steel plate 2 are clamped by the holding plates 3, 3 ', and a plasma torch 4 having a non-consumable electrode such as a cathode rod made of tungsten material or the like is caused to travel and a plasma arc is generated from the plasma torch. A method of welding the side surfaces of the foil 1 and the steel plate 2 with a simple arc was common.
しかし,従来のアーク溶接方法及び装置にあっては,
次のような欠点があった。However, in the conventional arc welding method and apparatus,
There were the following disadvantages.
(1)被溶接物である箔1と鋼板2との板厚が大きく異
なるため,ヒートバランスをとることが難しく,薄い方
の被溶接物である箔1が溶けてしまう。(1) Since the thickness of the foil 1 to be welded and the steel plate 2 are greatly different from each other, it is difficult to balance heat, and the thinner foil 1 to be welded is melted.
(2)被溶接物である箔1と鋼板2との側面を均一に合
わせなければならないので,箔1と鋼板2の切断面は精
度の高いものが要求される。(2) Since the side surfaces of the foil 1 and the steel plate 2 to be welded must be uniformly aligned, the cut surfaces of the foil 1 and the steel plate 2 are required to have high precision.
(3)被溶接物である箔1と鋼板2とをクランプしたと
きに,第5図にしめすように箔1が反ってしまうため,
箔1と鋼板2との溶接箇所に間隙ができてしまう。これ

結ばれてしまい,安定した溶接ができない。(3) When the foil 1 to be welded and the steel plate 2 are clamped, the foil 1 warps as shown in FIG.
A gap is created at the welding location between the foil 1 and the steel plate 2. In order to prevent this, if the holding plates 3, 3 'are brought close to the welding point of the foil 1 and the steel plate 2, an arc is connected to the holding plates 3, 3', and stable welding cannot be performed.

との突き合わせ溶接と同様の結果を得ることができる。FIG. 1 is a diagram for explaining one embodiment of the present invention. As shown in FIG. 1, a foil 1 and a steel plate 2,
Are placed so that the foil 1 is on the lower side and the steel plate 2 is on the upper side, and placed on the receiving table 6 on which the backing plate 5 is disposed. At this time,
The holding plate 3 'is stopped at the center of the backing plate 5, and the side surface of the steel plate 2 is formed with a groove having a width of, for example, 1 mm in the center of the backing plate 5 by abutting the steel plate 2 against the holding plate 3'. Located in the center of the back groove 7. Next, the pressing plate 3 is pressed,
The steel plate 2 and the foil 1 are clamped simultaneously. The width of the clamp shall be variable according to the thickness of the steel plate 2.
A scale 8 engraved on the backing plate 5 as shown in the figure is used. After the steel plate 2 and the foil 1 are simultaneously clamped by the holding plate 3, the holding plate 3 'is retracted to the required clamp width,
Clamp. The clamp width of these holding plates 3, 3 'is
The holding plate shall be close to the limit that does not interfere with the arc column emitted from the nozzle at the tip of the plasma torch 4.
Insulation coating is applied to the surfaces of 3, 3 'and they are clamped by air pressure. When the plasma torch 4 is run along the side surface of the steel sheet in such a state, the plasma torch 4 is tied to the side surface of the steel sheet 2 stacked on the arc foil 1 coming out of the plasma torch 4 and moves while melting this portion. I do. At this time, since the thermal energy for melting the side surface of the steel sheet 2 is, of course, sufficient to melt the lower foil 1, the foil 1 melts right and left and separates, and the foil 1 on the lower side of the steel sheet 2 is separated. Melts with the side surface of the steel plate 2 to form a weld bead. After the arc stops, the clamps on the holding plates 3, 3 'are released, and welding is completed. FIG. 3 is a view showing the work to be welded after the welding is completed, and shows a state in which the foil 1 and the steel plate 2 are welded by the welding beads 9. The foil 1 and the steel plate 2 thus welded are opened to open the foil 1 and the steel plate 2.
And the same result as in the butt welding can be obtained.

By fixing the foil 1 and the steel plate 2 to be welded and rotating the plasma torch 4 along the circumference of the steel plate 2, the foil 1 is blown into the shape of the circular steel plate 2 while one side of the steel plate 2 is melted. Can be welded.
