法に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention is directed to joining the edges of ultra-thin metal plates, such as stainless steel plates with a thickness of 0.15 mm or less, by a welding method such as TIG welding. The present invention relates to a method for welding ultra-thin plates.
（従来の技術）
薄い金属板の端縁部同志を溶接法により溶接す
る方法としては、特公昭46−19533号公報に開示
された４種の溶接方法がよく知られている。(Prior Art) Four types of welding methods disclosed in Japanese Patent Publication No. 19533/1982 are well known as methods for welding the edges of thin metal plates together.

保持した上、クランプされていない上記中央部分
をTIG溶接する方法である。 In addition, the second welding method is as shown in FIG.
The edge parts 11a, 11a of the metal plates 11, 11 are overlapped, and this overlapped part is held tightly by clamping 12, 12 except for the central part, and then the unclamped central part is TIG welded. This is the way to do it.
また第３の溶接方法は、第５図に示す如く、金

This is a method in which plate materials 15 of the same quality are stacked, the overlapping portions are tightly held by clamps 12, 12, and the unclamped portions are TIG welded.

をTIG溶接により溶融する方法である。 Furthermore, the fourth welding method is as shown in FIG.
The edge portions 11a, 11a of the metal plates 11, 11 are bent into an L shape, and the bent portions 11a, 11a are butted against each other, and a U-shaped member 16 of the same quality as the metal plate 11 is placed at this butt portion. Cover these 11
a, 11a, 16 are tightly integrated by caulking, and the bent portions 11a, 11a and the U-shaped member 16 are
This is a method of melting by TIG welding.
（発明が解決しようとする課題）

薄い場合には、突き合わせ精度を確保することが
困難となることは勿論、どうしても溶接部分に溶
孔を生じ易く、また溶接部分の機械的強度も不足
し、高品質の極薄板溶接物を得ることができな
い。(Problems to be Solved by the Invention) In the first welding method, the butt portions of the metal plates 11 and 11 are welded, so if the metal plates 11 are thin, it is difficult to ensure the butt precision. Needless to say, the welded part tends to form molten holes, and the welded part also lacks mechanical strength, making it impossible to obtain a high-quality ultra-thin plate welded product.
これに対して、第２〜第４の溶接方法では、金
属板１１，１１同志若しくはこれと別部材１５，
１６とを重合させ、その重合部分を溶接するよう
にしているから、金属板１１の板厚が薄い場合に
も上記不都合を生じることがなく、この点で、極
薄金属板の溶接方法としては第１の溶接方法に比
して優れたものといえる。 On the other hand, in the second to fourth welding methods, the metal plates 11 and 11 or a separate member 15,
16 and then welding the overlapped portion, the above-mentioned disadvantage does not occur even when the thickness of the metal plate 11 is thin, and in this point, it is a welding method for ultra-thin metal plates. It can be said that this welding method is superior to the first welding method.
しかし、重合部分を溶接するが故に次のような
問題があり、高品質の極薄板溶接物を能率良く製
作することが困難である。 However, because the overlapping parts are welded, the following problems arise, and it is difficult to efficiently produce high-quality ultra-thin plate welded products.
すなわち、板材１１，１５，１６の重合部分を
溶接する場合、板材間に空気が介在していると、
この介在空気部分が溶接熱により膨張破裂し、ビ

重合部分をクランプ１２，１２することによつ
て、また第４の溶接方法では重合部分をかしめる
ことによつて、重合部分を空気が介在しない密着
状態に保持するようにしている。 That is, when welding the overlapping parts of the plates 11, 15, and 16, if air is present between the plates,
This intervening air portion expands and ruptures due to the welding heat, causing problems such as disordered beads, making it impossible to perform good welding. Therefore, in the second and third welding methods, by clamping the overlapping parts 12, 12, and in the fourth welding method, by caulking the overlapping parts, the overlapping parts are brought into a close contact state with no air intervening. I try to keep it that way.
しかし第２及び第３の溶接方法の如く重合部分
をクランプ１２，１２しておくと、このクランプ

の如く金属板１１，１１が板厚方法に齟齬した状
態で接合すると、金属板１１，１１が面一状に接
合されない。 However, if the overlapping parts are clamped 12, 12 as in the second and third welding methods, the clamped parts will not be melted and will remain as overlapping steps, so it is necessary to perform a polishing finish after welding. Needless to say, there is a risk that gaps 17, 17 may occur, resulting in so-called interstitial corrosion. In particular, if the metal plates 11, 11 are joined in a state where the thickness method is inconsistent as in the second welding method, the metal plates 11, 11 will not be joined flush.
また第４の溶接方法の如く折曲部１１ａ，１１
ａの突き合わせ部分にコ字状材１６を被せ、これ

記のような問題は生じない。しかし、どうしても
溶接部分の肉厚が金属板１１の板厚に比して大幅
に厚くなり、金属板１１，１１を平滑に接合する
ことが出来ない。 Also, as in the fourth welding method, the bent portions 11a, 11
If the U-shaped material 16 is placed over the abutting portion of a, and the overlapping portions are closely integrated by caulking, the overlapping portions can be completely melted, and the above problem will not occur. However, the thickness of the welded portion inevitably becomes significantly thicker than the thickness of the metal plate 11, making it impossible to join the metal plates 11, 11 smoothly.

合部分１１ａ，１１ａ，１６をかしめておく必要

い。 Therefore, in the fourth welding method, it is necessary to polish the welded part after welding, and together with the need to caulk the overlapping parts 11a, 11a, 16 before welding, the workability is extremely high. Unfortunately, it is not possible to efficiently obtain high-quality ultra-thin plate welded products.
しかも、第３及び第４の溶接方法のように、被
溶接材たる金属板１１の他に別部材１５，１６を

ない。 Furthermore, as in the third and fourth welding methods, requiring separate members 15 and 16 in addition to the metal plate 11, which is the material to be welded, is not preferable in terms of manufacturing economy.

本構成とするものである。(Means for Solving the Problems) In order to achieve the above object, the ultra-thin plate welding method of the present invention welds one edge 1a and a shallow step of an ultra-thin metal plate with a thickness of 0.15 mm or less. The other edge 1 provided
1b , 1b near both edges of the ultra-thin metal plate.
is placed on a copper back bar 3 provided with a shallow groove-shaped recess 3b having a width slightly larger than the overlapping margin L1 on the upper surface side, and the overlapped end edges 1a, 1a are placed in a narrow groove-shaped groove. Copper clamps 2, 2 are positioned above the recess c and then opposed to each other with a distance L2 of 1.5 mm or less, to press the portions 1b near both ends onto the same plane of the back bar 3 from above. The two end edges 1a, 1b are fixed and brought into close contact with each other, and then the overlapped end edges 1a, 1a are completely melted by TIG welding so that the welded portion 1c is substantially smooth and has the thickness of the metal plate. The basic structure of the invention is to finish the material so that it is slightly thicker than the original material.

じることになる。 As the metal plate, an ultra-thin stainless steel plate with a thickness of 0.15 mm or less is generally used. Further, it is desirable that the overlap between both edges of the ultra-thin metal plate be within 1.0 mm (preferably less than 0.8 mm). That is, if the overlap exceeds 1.0 mm, it becomes difficult to finish the welded portion smoothly. On the other hand, if the overlapping margin L 1 is too small, a partial thin wall portion will occur in the welded portion.

In order to ensure adhesion between the edges and enhance the thermal and magnetic pinch effect of the arc,
Normally, it is desirable to keep it at 1.5 mm or less.

Since the entire portion a is melted, both end edges 1a of the ultra-thin metal plate can be welded well and strongly to each other in a substantially smooth state with almost no difference in thickness from the plate. Moreover, although both end edges 1a, 1a of the ultra-thin metal plates are superposed, the metal plates are not joined in a state that is inconsistent in the plate thickness direction as in the second welding method, and the two ultra-thin metal plates Boards can be joined flush. Furthermore, as in the second and third welding methods, there is no interstitial corrosion that causes interstitial corrosion;
Unlike the welding method described above, there is no need for caulking or polishing before and after welding, and the workability is good.
