Description of the Related Art In a chemical plant, a reprocessing plant or the like, for example, a dissimilar material joint of Zr and austenitic stainless steel used in a nitric acid environment is subjected to the following steps depending on the relationship between strength and corrosion resistance of the joint. A Ta thin plate is joined by explosive bonding on an austenitic stainless steel plate, and a Zr plate is explosively bonded on the Ta thin plate, which is further machined into a pipe. That is, the conventional method for producing a dissimilar joint pipe of Zr and stainless steel by explosion welding is
The steps shown in FIG. 2 are performed. In the figure, 01 is a stainless steel plate, 02 is a Ta thin plate, 03 is a Ta explosion-bonded joint, 04, 06, 08, 010, 012 are Zr, respectively.
Thin plate, 05, 07, 09, 011 and 013 are Z
This is the r-bonded joint. First, as a first step, as shown in FIG. 3A, a Ta thin plate 02 is bonded onto a stainless steel 01 by explosive bonding. Then, as shown in FIG. 3B, an explosive welding joint 03 of the stainless steel 01 and the Ta thin plate 02 is formed. Next, as a second step, as shown in FIG. 3C, the Zr thin plate 04 is bonded onto the Ta thin plate 02 by explosive bonding. After that, the Zr thin plates 06, 08, 010, 012 are successively deposited by explosion as shown in FIGS.
Are sequentially joined, and a thick plate of Zr composed of a plurality of thick layers is fixed in a sandwich form with stainless steel 01 with Ta sandwiched therebetween to form a dissimilar material joint as shown in FIG. Finally, as a third step, as shown in FIG. 4F, the pipe of the dissimilar joint is completed by making holes by machining.

た。However, in such a conventional method for producing dissimilar material joints (sandwiching Ta) of Zr and stainless steel by explosive welding, Ta thin plates are joined by explosive welding, and further Zr is used. The Zr portion must be thickened by joining the thin plates by multiple times of explosion welding. For this reason, not only the number of explosion-bonding steps is required, but also when manufacturing a dissimilar material joint pipe, the material yield is reduced, resulting in high material cost and work cost, and the dissimilar material joint pipe due to explosion-deposition is very costly. It will be higher. From the above, it has been desired to develop a method of manufacturing a dissimilar material joint pipe of stainless steel and Zr with Ta sandwiched between them at a low cost, which replaces explosion welding.
