This is a clad steel plate in which a thin copper plate and a stainless steel mesh are inserted between a temporary and titanium plate to form lava. However, this method involves interposing a copper thin plate and a stainless steel mesh, making it complicated and expensive. JP-A-56-80381 discloses a method of lap welding titanium and stainless steel through copper using an electron beam or laser beam, but this method requires expensive welding equipment to obtain large joints. .

Moreover, FIG. 3 is a diagram showing the joining method in this joining test, where A is the conventional method and B is the method of the present invention. As shown in test numbers 1 and 2 in Table 1, conventional joints made by spot welding titanium and steel without an insert material have low joint strength and do not give good results in bending tests. Test number 3.4 in Table 1 is a joint of the present invention, which is an example in which a W4 mesh or stainless steel T [Jil insert material is inserted into the joint surface of titanium material and steel and spot welded. A healthy joint with excellent properties can be obtained. Next, the effect of the joining according to the present invention will be explained. FIG. 1 is an enlarged cross-sectional view of the nugget portion of the joint of Test No. 3 in Table 1. 5 on the joint surface of titanium plate 2 and steel plate 3
IJS 304 and W 4 are inserted and spot welded, but in the nugget part, the 5OS304 mesh 4 is welded to the steel plate 3 as an integral part on the steel plate 3 side, and the part of the two temporary titanium parts is welded to the protrusion 5. It was pushed into the titanium temporary 2. That is, in the nugget part, titanium plate 2 and steel plate 3 are 5IJS.
They are interlocked in a concave and convex manner through 304 gold M44 to form a strong joint. FIG. 2 is a diagram showing the composition near the protrusion 5 in FIG. 1 using an automatic multifunctional analyzer (CMA).

る。Here, CMA refers to the distribution of components by irradiating multiple points (104 or more) on a sample surface with an electron beam in vacuum, measuring the generated characteristic X-rays (or reflected electrons), and processing these using a computer. This is an advanced image processing device for large samples using the principle of EPMA, which displays the status in color and performs qualitative and quantitative analysis (May 1984, Metals, extra issue special edition). In Figure 2, titanium plate 2 and steel plate 3 are SOS 30
4 By inserting a wire mesh, Ti-Fe-Cr-Ni
In addition to the bonding layer 7 of the steel plate and the bonding layer 8 of Ti-Fe, the steel plate and the stainless wire mesh are bonded by a Fe-Cr-Ni layer 9 with excellent strength and toughness that is directly bonded. The wire mesh of 5tlS 304 is pressed into the Ti plate to form a protruding Fe-Cr-Ni portion 6 which engages in a concave and convex manner. From Figures 1 and 2, the reason for the joint where the surface mating surfaces mesh in an uneven manner is as follows.
It is clear that the titanium plate, steel mesh, and steel plate were heated during welding, and the titanium plate became softer than the steel mesh at this heating temperature, so the steel mesh was pushed into the titanium plate by the pressure applied during welding. It is. That is, by inserting the ffJ mesh, the temperature of the contact area between the plate and the steel mesh is preferentially increased, and therefore, the interlocking joint as shown in FIGS. 1 and 2 can be obtained even with a relatively small pressure.

タン材の鋼網接触部の近傍はβトランザス以上に加熱さ
れ、鋼網よりも軟質となるために鋼網は押し込まれる。In the present invention, the titanium material may be either industrially pure titanium or a tan alloy. During electric resistance welding, the vicinity of the contact portion of these titanium materials with the steel mesh is heated to a temperature higher than the β transus, and the steel mesh is pushed into the titanium material because it becomes softer than the steel mesh.
鋼網の材質としては高温で硬質のオーステナイト系が望
ましい、 ＳＯＳ ３０４鋼網は入手が容易であるが、
ＳＯＳ ３１０系や５ＩＪＳ ３１６系の鋼網も高温で

電気抵抗溶接で優れた接合部が得られる材質の組合せが
、本発明でｍ網の材質や鋼板の材質を選定する際の組合
せとしても望ましい。The material for the steel mesh is preferably austenitic, which is hard at high temperatures.SOS 304 steel mesh is easily available;
SOS 310 series and 5IJS 316 series steel meshes are also hard at high temperatures. Also, part of the FJ net is welded to the steel plate, and the second
The welded layer shown in FIG. 9 is formed. By appropriately selecting the combination of the wire mesh material and the steel plate material, the welded layer shown in FIG. 2 and 9, which has excellent strength and toughness, is formed. That is, a combination of materials that can provide an excellent joint by ordinary electric resistance welding is also desirable as a combination when selecting the material of the m-mesh and the material of the steel plate in the present invention.
接合する鋼板は従って、炭素鋼、ステンレス鋼、合金鋼
の何れであってもよいが、第２図８の溶着層の靭性を高
めるために、炭素含有量の低いものが望ましい。Therefore, the steel plates to be joined may be made of carbon steel, stainless steel, or alloy steel, but in order to improve the toughness of the welded layer shown in FIG. 28, it is desirable that the steel plates have a low carbon content.

溶接条件は例えば薄い鋼網をインサート材として使用す

じて接合を行う事ができる。Pressure joining by electric resistance welding includes spot welding, seam welding,
It can be applied to upset welding, butt seam welding, etc., and when a thin steel mesh is used as an insert material, the welding conditions can be the same as in Table 1 when no insert material is inserted.

本発明によりｍｓのインサート材を介挿し溶接すると、
接合特性の優れた溶接部が得られる。又本発明では汎用

る。Direct welding of titanium and steel results in brittle welds, but
When inserting and welding ms insert material according to the present invention,
A welded part with excellent bonding properties can be obtained. Further, in the present invention, titanium material and steel can be easily joined using general-purpose joining equipment.
