本発明は、拡散溶接による継手溶接法に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint welding method by diffusion welding.
拡散溶接とは、被溶接材を真空中又は不活性ガ
ス雰囲気中において再結晶温度以上に加熱し、固
相の状態で溶接面を加圧して接合する方法であ
る。 Diffusion welding is a method in which the materials to be welded are heated in a vacuum or in an inert gas atmosphere to a temperature higher than the recrystallization temperature, and the welding surfaces are pressurized in a solid state to join the materials.
従来の拡散溶接は、第１図Ａ，Ｂに示すような
継手形状で行われていた。 Conventional diffusion welding has been performed with joint shapes as shown in FIGS. 1A and 1B.
第１図Ａ，Ｂ中、被溶接材を１，２、溶接部を
３、被溶接材１，２の長さをａ、幅をｂ、板厚を
ｔで示す。 In FIGS. 1A and 1B, the materials to be welded are indicated by 1 and 2, the welded portion is indicated by 3, the length of the welded materials 1 and 2 is indicated by a, the width is indicated by b, and the plate thickness is indicated by t.
第１図Ａの場合は、被溶接材１，２の長さａ、
幅ｂは、板厚ｔに対して非常に大きいため、被溶
接材１，２の上下より加圧力を負荷すれば、良好
な拡散溶接が施工できる。 In the case of Fig. 1 A, the length a of the materials to be welded 1 and 2,
Since the width b is very large compared to the plate thickness t, good diffusion welding can be performed by applying pressure from above and below the materials to be welded 1 and 2.
しかし、第１図Ｂのように、被溶接材１，２の
長さａ、又は幅ｂが板厚ｔに対して非常に小さい

変形し、拡散溶接は不可能となる。 However, as shown in FIG. 1B, when the length a or width b of the materials to be welded 1 and 2 is extremely small relative to the plate thickness t, good diffusion welding cannot be performed. The reason for this will be explained with reference to FIG. That is, when pressure is applied from above and below the materials to be welded 1 and 2, the materials to be welded 1 and 2 undergo buckling deformation as shown by dotted lines in FIG. 2, making diffusion welding impossible.

明に到達したものである。 While considering a butt welding method using diffusion welding for thin long plates, the present inventors devised the shape of the joint weld, as shown in Figure 1B, which was difficult to perform in conventional diffusion welding. The present invention was developed based on the finding that joint welding of materials with previously used shapes and dimensions can be easily performed.

よる継手溶接法に関するものである。 That is, in the joint welding method using diffusion welding, the present invention provides a joint welding surface of each of the materials to be welded with an uneven interlocking structure, and a step is provided between the materials to be welded in the meshed state of the joint. The present invention relates to a joint welding method using diffusion welding, which is characterized in that diffusion welding is performed by applying pressure to the joint in a direction that eliminates the step.
以下、添付図面を参照して本発明方法を詳細に
説明する。 Hereinafter, the method of the present invention will be explained in detail with reference to the accompanying drawings.

いる。 In FIGS. 3A to 3E, the same reference numerals as in FIGS. 1A and B indicate the same parts as in FIGS. At the same time as having an interlocking structure, they are processed so that a step 5 is provided in each of them in this interlocking state.

である。 Heat to the required temperature in the conditions shown in Figure 3 A to E,
Thereafter, pressure is applied in the direction of arrow 4 until the step 5 is plastically deformed and disappears, thereby completing the joining.

となるのである。 As described above, in the method of the present invention, the welded cross sections of the welded materials 1 and 2 are not linear surfaces as in the conventional method, but have a structure in which they mesh with each other. At this time, the applied pressure force is transmitted as is to the part of the joint surface located perpendicular to the pressure direction 4, and to the part with an inclination, a component force of the pressure force is transmitted according to the inclination. . In addition, the bonding surface is
In the parts located in the same direction as the welding materials 1 and 2, the pressure force is not transmitted and joining is impossible.
Due to the compressive plastic deformation of the stepped portion 5 provided in the step 5, the metal flows into the concave and convex portion of the mutually engaged joint and generates a lateral pressurizing force. It also becomes possible to join the located parts.
