Description of the Related Art In a chemical plant, a reprocessing plant, or the like, for example, a dissimilar joint made of Zr and austenitic stainless steel used in a nitric acid environment is subjected to the following steps depending on the strength and corrosion resistance of the joint. A thin Ta plate is bonded on an austenitic stainless steel plate by explosion, and then a Zr plate is exploded on the Ta thin plate, and further processed into a tube by machining. That is, the conventional method of manufacturing a dissimilar joint pipe made of Zr and stainless steel by explosion is as follows.
In FIG. 2, reference numeral 01 denotes a stainless steel plate, 02 denotes a Ta thin plate, 03 denotes a Ta explosive joint, and 04, 06, 08, 010, and 012 denote Zr, respectively.
Thin plate, 05,07,09,011,013 are each Z
This is the explosive joint of r. First, as a first step, a Ta thin plate 02 is joined on a stainless steel 01 by explosion as shown in FIG. Then, as shown in FIG. 4B, an explosive joint 03 between the stainless steel 01 and the Ta thin plate 02 is formed. Next, as a second step, the Zr thin plate 04 is joined to the Ta thin plate 02 by explosion as shown in FIG. Thereafter, as shown in FIGS. 3D and 3E, the Zr thin plates 06, 08, 010, 012 are successively exploded.
Are sequentially joined, and a thick Zr thick plate composed of a plurality of layers is fixed in a sandwich shape to the stainless steel 01 with Ta interposed therebetween, thereby forming a dissimilar material joint as shown in FIG. Finally, as a third step, as shown in FIG. 3 (F), a pipe of a dissimilar material joint is completed by drilling by machining.

た。However, in such a conventional method of making a dissimilar joint (with Ta interposed) between Zr and stainless steel by explosion, a Ta thin plate is joined by explosion, and then Zr is further exploded. The Zr portion must be made thicker by joining the thin plates by explosion welding a plurality of times. This not only requires explosion man-hours, but also reduces the material yield when manufacturing dissimilar joint pipes, resulting in high material and work costs, and the explosive dissimilar joint pipes are very costly. It will be higher. In view of the above, it has been desired to develop a method for manufacturing a dissimilar material joint pipe of stainless steel and Zr sandwiching Ta with a low cost and high reliability in place of explosion.
