In particular, it relates to a joining method using liquid phase diffusion joining.

される。As a butt-joining method for plate materials, pipe materials, and strip materials, there is diffusion bonding in which the vicinity of the bonding surface is heated and pressed so that plastic deformation hardly occurs, and the diffusion of atoms generated between the bonding surfaces is used for bonding. is there. This diffusion bonding is roughly classified into the following three.

の融点以下の温度に加熱を行う液相拡散接合である。One is solid phase diffusion bonding in which the materials to be bonded are directly contacted with each other and the vicinity of the bonding surface is heated at a temperature lower than the melting point of the materials to be bonded. The second is solid-state diffusion bonding in which an insert material of a dissimilar metal is inserted between the bonding surfaces and heating is performed at a temperature lower than the melting point of either the material to be bonded or the insert material. The third is liquid phase diffusion bonding in which an insert material having a melting point lower than that of the material to be bonded is inserted into the bonding surface and heating is performed at a temperature higher than the melting point of the insert material and lower than the melting point of the material to be bonded.

合わせ接合に使用されている。Solid-phase diffusion bonding without using an insert material is used for manufacturing a complex shaped article such as an aircraft member. Solid phase diffusion bonding using an insert material is often used to manufacture a clad plate, a clad tube, and a clad rod by a rolling method rather than a butt bonding. The third liquid phase diffusion bonding is used for, for example, butt bonding of pipe materials and strip materials.

に等温凝固して接合が完了する。Among these diffusion bonding methods, in the liquid phase diffusion bonding, the insert material inserted between the bonding surfaces once becomes a liquid phase at a heating temperature, and the voids due to the unevenness between the bonding surfaces are filled with molten metal. While being maintained at the joining temperature, mutual diffusion occurs between the insert material and the material to be joined, and finally isothermic solidification and joining is completed.

生させるのである。The liquid-phase diffusion bonding method is excellent in efficiency and does not require special skill, and can be bonded without deformation of the appearance of the materials to be bonded. Although it has an excellent feature that a joining portion can be obtained, on the other hand, there is a drawback that in butt joining, in particular, the occurrence of misalignment of the joining surface in a direction parallel to the surface cannot be avoided. The main reason for this is that the dimensions of the materials to be joined (for example, plate thickness, pipe diameter, and wall thickness) are not constant, and there are always tolerances. Even if you remove the dimensional tolerance
The material to be joined is displaced when the material to be joined is set by sandwiching the insert material or due to the pressure applied at the time of joining, which causes misalignment.

報告されているように、非破壊検査時に目違いが妨害と
なり、充分な検査を行えなくなる。図４は超音波探傷時
に目違いが問題となる様子を示している。When a misalignment occurs, stress concentrates there and not only the fatigue strength lowers, but also as reported in "Welding Society National Lecture Summary, Vol. 47, 1990.10 86-87". However, the non-destructive inspection interferes with the misregistration, making it impossible to perform a sufficient inspection. FIG. 4 shows how misregistration becomes a problem during ultrasonic flaw detection.

もコーナエコーを本来の欠陥エコーから識別することは
難しい。従って、目違いを残したままではコーナエコー
より大きいエコーを生じる欠陥しか検出できない。In the oblique-angle flaw detection test for butt joints, the joint 2 is usually detected from both sides with the probes 3, 3 sandwiching the joint 2 of the materials 1 and 1 to be joined. Joint 2
When the ultrasonic wave emitted from the probe 3 hits a corner generated by the misalignment, a so-called corner echo is generated and the echo height becomes large. When a corner is flaw-detected in the state of FIG. 4, the echo height on the A side is theoretically B
It should be larger than the echo height on the side, and it should be possible to identify the corner echo from the difference, but there is almost no difference in the height depending on the difference in size and shape. It is difficult to distinguish from a defect echo. Therefore, it is possible to detect only a defect that produces an echo larger than the corner echo without leaving any misalignment.

らである。Therefore, depending on the size of the misalignment, work for removing the misalignment is performed by machining or the like. However, the work is troublesome, and even if the misalignment is removed, defect detection capability is expected. Not much better. This is because, in the conventional bevel flaw detection test of the butt portion, the ultrasonic wave from the probe 3 is applied to the bonding interface 4 as shown in FIG.
This is because the defect echoes that do not hit the probe 3 are scattered in a direction other than the probe 3 and the number of defect echoes returning to the probe 3 is reduced.

囲が飛躍的に拡大する。As is apparent from the above description, in the metal joining method of the present invention, since the misalignment is reduced by engaging the joining surfaces, the fatigue strength of the joining portion can be improved. In the destructive inspection of joined joints, it is not necessary to remove the misalignment, and even if the misalignment is not removed, the deterioration of the defect detectability due to the corner reflection is prevented. The defect detectability is also improved by making the light incident on. Therefore, it is possible to obtain a joint with high performance and high reliability, and the applicable range of liquid phase diffusion bonding is dramatically expanded.
