Description of the Related Art Overlay welding of dissimilar metals refers to a mating material such as stainless steel having a higher corrosion resistance than a base metal or a base metal such as general carbon steel. Add a new function to the above-mentioned general carbon steel by forming a composite metal layer on the surface of the base metal by melting the composite metal such as high-hardness alloy such as stellite which has abrasion properties. Is what you do. A material obtained by covering the surface of a base metal represented by carbon steel with another metal and adding a new function is called a clad steel and is defined by Japanese Industrial Standards. As a method of manufacturing clad steel other than the overlay welding specified in Japanese Industrial Standards, a hot rolling method, a diffusion bonding method, and an explosion bonding method are performed.

９５号公報が知られている。Unlike the hot rolling method and the diffusion bonding method described above, the clad steel formed by overlay welding does not require the entire clad steel to be heated to a high temperature. It can be forged steel. Further, the clad steel formed by the build-up welding method has an advantage that the thickness of the joining material metal can be made to be an arbitrary thickness by devising welding conditions. In connection with clad steel by overlay welding,

によるクラッド材の製造は殆ど不可能であった。[0004] In the overlay welding clad, since the molten high-temperature weld metal is deposited on the surface of the base material, a dilution phenomenon of the weld metal due to the base metal component often occurs. Therefore, when fabricating a cladding cladding, it is necessary to perform a cladding welding by adding a dilution thickness. In addition, in the case of a combination of metals that generate a hard and brittle intermetallic compound in the diluted part, overlay welding is difficult, and in particular, aluminum and iron-based metal materials, titanium and iron-based metal materials, zirconium and iron-based metal materials are used. It was almost impossible to produce clad material by overlay welding.

It is made by metallurgical joining method such as explosion crimping method, but explosion crimping method is preferable in terms of joining strength, and furthermore, when heat treated steel or forged steel is used as the base material of metal composite plate, there is almost no heat effect Explosive crimping is particularly effective. The metal composite plate is not limited to two layers, and a multilayer metal composite plate having three or more layers can be used as necessary. The metal of the outermost layer on which the overlay welding of the metal composite plate is performed is selected from a combination of metals that hardly generates a brittle intermetallic compound in a diluted portion with the overlay welding, and preferably, a diluted portion. A metal of the same material as the build-up material that does not require additional thickness is selected. Further, the thickness of the metal plate is set at 0.000 in consideration of the fact that the welded portion formed by overlay welding does not reach the metallurgically bonded interface of the metal composite plate and the manufacturing process of the metal composite plate.
It is necessary to be in the range of 1 mm to 50 mm, and preferably, it is set in the range of 1 mm to 10 mm. The overlay welding is performed by a commonly used welding method such as arc welding, MIG welding, or TIG welding.

After joining by explosion crimping to produce a metal composite board,
Titanium overlay welding was performed on the surface of the industrial pure titanium to form a titanium layer having a total thickness of 10 mm. The overlay welding was performed in a state where a part of the metal composite plate was immersed in running water so as not to apply excessive heat to the joint interface of the metal composite plate. From the metal composite material manufactured by the above-mentioned manufacturing method, a micro test piece for observing a joint interface and a build-up weld and a shear strength test piece for measuring the joint strength of both metals were collected. As a result, the welded portion of the overlay welding did not reach the bonding interface of the explosion bonding, and no dilution of the titanium and the carbon steel sheet was observed. No harmful diffusion layers were formed at the bonding interface of the explosion bonding. The build-up weld was in a healthy state with no cracks or burrs. Shear strength is 244 to 27
