Forming a joint that integrally forms a laminated plate with a substrate such as an aluminum-steel transition joint material of a transportation ship. Anchor fitting engagement of the laminated plate of the other plate to the anchor recess of the one plate. Since it can be mechanically coupled by anchor bond integral joining by, the longitudinal shear resistance is significantly enhanced by longitudinally and laterally fitting engagement of the anchor recess and anchor of the plate body such as the substrate, The excellent effect is that the initial binding function does not change over time, and thus the function is always maintained.

Further, there is an effect that the joint performance of the joined body is homogenized, and the performance of a long joined body or a joined body having a large area can be further promoted.

Thus, in the manufacturing method, the groove is formed in the plate body such as the substrate by roll rolling, machining, forging or the like, and the anchor is formed by inwardly forming the recessed groove. There is an effect that it is easy to form the concave portion or to engage and engage the anchor with the anchor concave portion, and therefore the manufacturing cost is reduced and the accuracy can be improved.

Further, the anchor recess of one plate is formed by a forming roll, and the raised portions on both sides of the groove of the anchor recess are flatly rolled by a rolling roll having a peripheral groove having a triangular cross section having a pair of slopes. As a result, the excellent effect that the groove-shaped concave portions having the overhang portions symmetrically on both sides of the neck portion of the groove can be formed as designed is exhibited.
