スを製作し、これを利用する試みがなされている。(Prior Art) In a boiler or the like, dissimilar material joint welding is often performed between a pipe used in a high temperature place (for example, stainless steel) and a pipe used in a low temperature place (for example, chrome molybdenum steel). However, in this case, it is difficult to obtain a transient piece (dissimilar material welded joint) that can withstand severe operating conditions even if a relatively high-grade welding rod (for example, 25Cr-20Ni-based welding rod) is used. is there. Therefore, in recent years, as described in Sumitomo Metal Technical Report (October 1967) Vol.19 No.4 P.482-493, a transient in which an insert material such as Inconel is sandwiched between both pipes by a friction welding method. Attempts have been made to make pieces and use them.

た。(Problems to be Solved by the Invention) However, according to the above friction pressure welding method, there is a problem in that it takes time because the pressure welding has to be performed twice. When the first press contact is performed, it is necessary to hold the insert material by a chuck. Therefore, the insert material must have a chuckable length. Has a problem that it is uneconomical because it is necessary to use a long one so that a part of it is cut off later.

Therefore, unlike the above-mentioned conventional method, it does not require any trouble. Further, since it is not necessary to chuck the ring-shaped insert material, it is possible to use a thin-walled insert material, which makes it possible to cut off a part of this after using a long insert material as in the conventional method. You will not have to do anything uneconomical.

ととなる。First, as shown in FIG. 1, a case of manufacturing a joint in which a ring-shaped insert material 3 is sandwiched between tubular joined parts 1 and 2 such as a transient piece will be described. As a first step, FIG. As shown, one member 1 to be joined and the other member 2 to be joined are coaxially opposed to each other, and the ring-shaped insert material 3 is also coaxially arranged therebetween.
In this case, as shown in FIG. 5 (a), for example, one joined member 1 is the rotating side and the other joined member 2 is the fixed side, and the abutting side end of the joined member 2 on the fixed side. The holding member 4 is inserted into the holding member 4, and the ring-shaped insert 3 is rotatably fitted and held on the outer periphery of the exposed end of the holding member 4. The shape of the holding member 4 may be any shape as long as it can rotatably hold the ring-shaped insert material 3. For example, as shown in FIGS. 6 (a) to 6 (f), a cylinder is used. Shaped (see (a)), cylindrical shaped with slits 5 along the axial direction (see (b)), cylindrical shaped (see (c)), cylindrical shaped with axial direction Formed with deep groove 6 (see (d)), small diameter portion 7 (see (e)), circumferential flexible bone structure 8 (see (f)), etc. Is appropriate. If the structure shown in Fig. 6 (e) (f) is used, Fig. 7 (a)
As shown in (b), it is possible to secure a space for discharging the inner flash. The material may be ceramics or inexpensive metal. Then, in the next step, as shown in FIG. 3, both members 1 and 2 to be joined and the ring-shaped insert material 3 set as described above are simultaneously friction-welded by rotating one member 1 to be joined. To do. In this case, the ring-shaped insert material 3 is rotated by following the member 1 to be joined on the rotating side, and is repeatedly stopped by friction with the member 2 to be joined on the stationary side while being joined to both members 1 and 2 to be joined. It will be in a state of being pressure-welded (two-side friction welding). Therefore, the holding member 4 is removed, and as a final step, the flash 9 formed between the members 1 and 2 to be joined and the ring-shaped insert material 3 is removed as shown in FIG. Will be completed.

面形状について制限を受けることはない。That is, according to the method of the above-mentioned embodiment, since the three members 1, 2, and 3 can be simultaneously joined by one press contact, unlike the above-mentioned conventional method, no labor is required. Further, since it is not necessary to hold the ring-shaped insert material 3 by a chuck, it is possible to use a thin-walled insert material, which makes it possible to use a long insert material as in the above-mentioned conventional method and cut a part thereof later. There is no need to do it. Therefore, in this respect as well, it does not take a lot of trouble,
And it will be economical. Further, since the ring-shaped insert material 3 does not need to be held by a chuck, its planar shape is not limited.

設定可能である。In the above, the case where both the members to be joined 1 and 2 are tubular has been taken as an example, but in the above method, as shown in Fig. 5 (b), one of the members to be joined 1 is solid. It is possible to apply even the thing. Further, it is not always necessary that one joined member 1 is the rotating side and the other joined member 2 is the fixed side, and both members may be rotated and rotated in opposite directions. Further, the holding member 4 does not necessarily have to be a separate body from the members to be joined 1 and 2 (this is easier to work), but may be integrated. The materials of the members 1 and 2 and the ring-shaped insert material 3 can be set arbitrarily.

2 has a cylindrical shape with a diameter of 34 mm, a length of 50 mm and a thickness of 4.5 mm, and the ring-shaped insert material 3 has a ring plate shape with a diameter of 38 mm, a length of 3 mm and a thickness of 11.5 mm. The conventional method (brake method) was adopted as the pressure welding method. In addition, there are inner shear methods and the like, but the above friction welding method can be applied to any method. Each symbol in FIG. 8 indicates P1: frictional pressure, P2: upset pressure, t1:
Friction time, t2: upset time, N: number of revolutions, l: total deviation, l1: friction deviation, l2: upset deviation,
While the ring-shaped insert material 3 is rotatably held between the one and the other joined members 1 and 2, the one joined member 1 is rotated at a given friction pressure P1 for a predetermined time t1, while the other joined member is joined. It is pressed against the 2 side, after which the rotation is stopped and the upset pressure P2 is applied.
