本発明は、Ｔ字継手の高エネルギー密度による貫通溶接
方法に係り、特にＴ字継手の貫通溶接による接合に好適
な継手形状に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for welding T-joints using high energy density, and more particularly to a joint shape suitable for joining T-joints by penetration welding.

部品の肉厚を増す必要があった。Conventionally, T-joints are generally joined by fillet welding the upper and lower plates, by drilling a hole in the upper plate and joining the lower plate by plug welding, or by using solder between the upper and lower plates. This was done by inserting materials and brazing them, by diffusion bonding the upper and lower plates, or by interfacial alloying bonding. However, the fillet welding method,
Plug welding requires a lot of man-hours, and brazing, diffusion bonding, and interfacial alloying bonding require heating the entire base metal, which requires a wide heating range and causes significant softening.
It was necessary to increase the thickness of the parts.

It has become possible to join joints by penetration welding. Fifth
The figure shows the principle diagram. That is, by applying an electron beam (the same applies to a laser beam) to the upper plate 1 as shown in the figure, the weld metal 4 penetrates the upper plate 1 and reaches the lower plate 2 as shown by the dotted line, and the upper plate 1 and the lower plate 2 can be welded together. According to this method, although the upper plate 1 and the lower plate 2 are locally softened, deterioration in overall strength can be prevented, and the thickness and weight can be reduced.

ードの凹みを生じ、良好な溶接が困難であるなどの問題
がある。The development of high-energy density welding methods has made it possible to join T-joints by penetration welding, but due to variations in dimensional accuracy and the effects of distortion occurring in the surrounding joints, gaps between the upper and lower plates occur. If this occurs, there are problems such as the molten metal of the upper plate flowing out through the gap, making it impossible to weld, or creating bead dents on the upper plate, making it difficult to perform good welding.
第６図はこれを説明する図で、３は上板１と下板２の間
に生じた隙間であり、該隙間から溶融金属４が外へ流出
し、上板１にビードの凹み６が生じることを示している
。FIG. 6 is a diagram explaining this, and numeral 3 indicates a gap created between the upper plate 1 and the lower plate 2, through which the molten metal 4 flows out and a bead dent 6 is formed in the upper plate 1. It shows that it will occur.
本発明の目的は、上板と下板の隙間があっても、高エネ
ルギー密度貫通溶接法によるＴ字継手の接合を可能にし
て、構造部材の薄肉化、軽量化を図ることにある。An object of the present invention is to make it possible to join a T-joint by high energy density penetration welding even if there is a gap between the upper and lower plates, thereby reducing the thickness and weight of a structural member.
上記目的は、下板の上板と接する面を凹状とすることに
より達成される。The above object is achieved by making the surface of the lower plate in contact with the upper plate concave.

外部への流出を防止することができる。When joining T-joints by penetration welding using high energy density, even if there is a gap between the upper and lower plates, the molten metal on the upper plate is caught in the concave part of the lower plate, and even if it flows out from there, , the molten metal cools and solidifies in the middle of the outflow path,
It is possible to prevent leakage to the outside.
以下、本発明の一実施例について図面により説明する。 An embodiment of the present invention will be described below with reference to the drawings.

上板１と接合する面を受皿形状にした実施例である。上
板１と下板２を図のように組合せ。FIG. 1 is a sectional view of one embodiment of the present invention, and this is an embodiment in which the surface of the lower plate 2 to be joined to the upper plate 1 is shaped like a saucer. Combine upper plate 1 and lower plate 2 as shown in the diagram.

中で冷却凝固し、外部への流出を止めることができる。Electron beam (same as laser beam) 5 is placed on top plate 1
When applied from above, the molten metal 4 penetrates the upper plate 1 and reaches the lower plate 2 as shown by the dotted line, making it possible to weld the upper plate 1 and the lower plate 2 together. In this case, as shown in FIG. 3, even if there is a gap 3 between the upper plate 1 and the lower plate 2, the surface of the lower plate 2 in contact with the upper plate 1 has a saucer shape, so the upper plate 1 molten metal 4
is received by the saucer portion. Moreover, even if the molten metal 4 flows out from the receiving tray, since the outflow path is long, it will cool and solidify midway through the outflow path, thereby stopping the outflow to the outside.
したがって、上板１と下板２は確実に接合し、また、上
板１にビードの凹みが生じることもない。Therefore, the upper plate 1 and the lower plate 2 are reliably joined, and no bead dents are formed in the upper plate 1.

できる。FIG. 2 is a sectional view of another embodiment of the invention, which shows the lower plate 2.
The surface in contact with the upper plate 1 is made into an inset shape, so that its outer peripheral part is higher than the other parts. In this case as well, even if a gap 3 is formed between the upper plate 1 and the lower plate 2 as shown in FIG. 4, the molten metal 4 of the upper plate 1 can be prevented from flowing out.
以上説明したように、本発明によれば、高エネルギー密

、薄肉化、軽量化が達成される。Since the T-joint can be joined reliably and without the occurrence of bead dents, deterioration of the strength of the entire structure can be prevented, and the wall thickness and weight can be reduced.
