ってない。2. Description of the Related Art A titanium-clad steel sheet is a steel sheet in which titanium (called a composite material) having extremely excellent corrosion resistance is bonded to the surface of a steel sheet (called a base material) as a strength member, which is advantageous in cost. Therefore, its use is expanding in fields such as marine structures, chemical plants, and power plants, which have severe usage environments. However, it has not yet been used in large quantities due to the welding problems described below.

題がある。When a titanium clad steel sheet is welded by a usual method, a brittle intermetallic compound or a titanium carbonitride is formed in a portion where a dissimilar metal of titanium and steel is melted (called a dissimilar material welded portion). The part is easily broken. For this reason, welding of titanium clad steel sheet is performed by vacuum brazing method or diffusion bonding method that inserts insert material that does not generate intermetallic compound, but expensive vacuum equipment and precious metal insert material are used. There are problems such as high cost, limited size, and the inability to perform welding at the construction site.

開示されている。In order to solve such welding problems,
Conventionally, several methods have been proposed. For example, JP-A-2-280969 and JP-A-2-280970 disclose a joining material of a butt portion to be welded,
A groove is provided in the base material from which the bonding material has been removed, and the base material is welded.
A method is disclosed in which titanium of the same quality as that of the bonding material is put on the welded portion as a spacer, and a method of further covering the same with a titanium backing plate is disclosed.

Therefore, at both ends of the welded portion, corrosive gas or liquid enters through the gap to cause corrosion of the welded portion, or because the welding is performed by a normal method, the fragile intermetallic compound as described above. Are generated and cracks occur.

FIG. 2A shows a state after the base material 3 is welded.
(B) shows the state after the clad spacer 9 has been inserted into the cut 10 at the end of the base metal weld 4 and welded, and (c) shows the base metal weld 4 and its surroundings with the titanium backing plate 6. This shows the state after cover welding.

てプラズマ溶接やＴＩＧ溶接で行う。Next, as shown in FIG. 2B, a clad spacer 9 of the same quality as the titanium clad steel plate 1 is inserted into a notch 10 formed at the end of the base metal welded portion 4 and welded.
At this time, the welding of the dissimilar material welded portion 8 on the side surface where titanium and steel are melted is performed by plasma welding or TIG welding using an Ag-Cu-based material in an inert gas atmosphere.

属間化合物などの生成が妨げられる。Since the clad spacer 9 is inserted into the end and welded, no corrosive gas or the like enters through the gap. Further, in the dissimilar material welded portion 8, since the welding is performed in an inert gas atmosphere, an oxide or a nitride is not generated, and the welding speed is high by using an Ag-Cu-based material capable of lowering the melting point. Since it is performed by plasma welding or TIG welding, the reaction between titanium and iron is suppressed, and the formation of such intermetallic compounds is prevented.
