アルミ製品と鋼材製品とを接合する場合に、両者を直接溶接すると両者の間に脆い金属間化合物が生成されるために接合強度のばらつきが大きくなり、そのため接合の信頼性が低いものとなってしまう。 When joining aluminum products and steel products, if they are directly welded, a brittle intermetallic compound is generated between them, resulting in a large variation in joining strength, which results in poor joint reliability. End up.
そこで、アルミ製品と鋼材製品との間に、アルミ単独又はアルミと鉄系金属をクラッドした中間材料をインサート材として介在させて抵抗溶接する接合方法が提案された（例えば、特許文献１および特許文献２参照。）。
しかし、アルミ製品と鋼材製品との間にインサート材を介在させて接合する工法では、既存・既設の設備を用いることが非常に難しく、例えば自動車の車体等を組み立てる工程において自動化することが困難となる。自動車の車体等を組み立てる工程以外にも、既存・既設の接合条件から大幅な変更または調整を余儀なくされるので、接合条件の管理幅が非常に狭いものになることが多くなり、安定した製造(接合加工)が困難になる。
Therefore, there has been proposed a joining method in which resistance welding is performed by interposing an intermediate material clad with aluminum alone or aluminum and an iron-based metal as an insert material between the aluminum product and the steel product (for example, Patent Document 1 and Patent Document). 2).
However, it is very difficult to use existing / existing equipment in the construction method in which an insert material is interposed between an aluminum product and a steel product. For example, it is difficult to automate in the process of assembling the body of an automobile. Become. In addition to the process of assembling automobile bodies, etc., it is necessary to make significant changes or adjustments from existing and existing joining conditions, so the management range of joining conditions is often very narrow and stable manufacturing ( Joining) becomes difficult.
本発明は、アルミ製品と鋼材製品とを接合する場合に、既存・既設の接合工程及び設備を変更することなくそのまま利用してアルミ製品と鋼材製品とを接合組み立てることができ、従って、既存・既設の接合条件管理レベルでもって製造(接合加工)することが可能なアルミ製品と鋼材製品との接合用継ぎ手及びそれを用いた接合方法を提供することを目的とする。 In the present invention, when joining aluminum products and steel products, the existing and existing joining processes and equipment can be used as they are without modification, and the aluminum products and steel products can be joined and assembled. It is an object of the present invention to provide a joint for joining an aluminum product and a steel product that can be manufactured (joined) with an existing joining condition control level and a joining method using the joint.
上記の目的を達成する本発明の接合用継ぎ手は、アルミ製品と鋼材製品とを接合するための継ぎ手であって、対アルミとの密着性に優れる表面処理が施されアルミ製品と一体化されるアルミ側鋼板と、対鋼材との溶接性に優れる表面処理が施され鋼材製品と一体化される鋼材側鋼板とを溶接により一体化して構成されている事を特徴としたものである（請求項１）。
この際、前記アルミ側鋼板と鋼材側鋼板とは、鋼板同士を溶接する場合に一般的に適用されている例えばシーム溶接により溶接される。
The joining joint of the present invention that achieves the above object is a joint for joining an aluminum product and a steel product, and is surface-treated with excellent adhesion to aluminum and integrated with the aluminum product. The aluminum-side steel plate and the steel-side steel plate that is integrated with the steel product are subjected to a surface treatment excellent in weldability with the steel material, and are characterized by being integrated by welding (claims). 1).
Under the present circumstances, the said aluminum side steel plate and the steel material side steel plate are welded by the seam welding generally applied, for example, when welding steel plates.
また、本発明に係る別の接合用継ぎ手は、１枚の鋼板の一部に、対アルミとの密着性に優れる表面処理が施されアルミ製品と一体化されるアルミ側接合部と、対鋼材との溶接性に優れる表面処理が施され鋼材製品と一体化される鋼材側接合部とが形成されている事を特徴としたものである（請求項２）。 In addition, another joint for joint according to the present invention includes an aluminum-side joint that is integrated with an aluminum product by applying a surface treatment with excellent adhesion to aluminum to a part of one steel plate, and a steel product. A surface treatment excellent in weldability is applied to form a steel material side joint that is integrated with the steel product (Claim 2).
前記対アルミとの密着性に優れる表面特性は、前記アルミ側鋼板又はアルミ側接合部の表面を溶融亜鉛被覆処理することにより付与され（請求項３）、また、対鋼材との溶接性に優れる表面特性は、前記鋼材側鋼板又は鋼材側接合部の表面に合金化亜鉛めっき処理を施すか又は素地面とすることにより付与される（請求項４）。 The surface property excellent in adhesion to the aluminum is imparted by subjecting the surface of the aluminum-side steel plate or aluminum-side bonded portion to a hot dip galvanizing treatment (Claim 3), and is excellent in weldability with the steel material. The surface characteristics are imparted by subjecting the surface of the steel material-side steel plate or steel material-side joint portion to galvannealing or forming a bare surface (Claim 4).
そして、本発明のアルミ製品と鋼材製品との接合方法は、対アルミとの密着性に優れる表面処理が施されたアルミ側鋼板と、対鋼材との溶接性に優れる表面処理が施された鋼材側鋼板とを溶接により一体化してなる接合用継ぎ手を用い、前記アルミ側鋼板にアルミ製品を一体化せしめ、然る後に前記鋼材側鋼板に鋼材製品をスポット溶接又はアーク溶接により一体化することにより前記アルミ製品と鋼材製品とを接合する事を特徴としたものである（請求項５）。 And the joining method of the aluminum product of this invention and steel material products is the steel material by which the surface treatment which was excellent in the weldability of the aluminum side steel plate in which the surface treatment which was excellent in the adhesiveness with aluminum, and the steel material was performed. By using a joint for welding which is integrated with the side steel plate, the aluminum product is integrated with the aluminum side steel plate, and then the steel product is integrated with the steel side steel plate by spot welding or arc welding. The aluminum product and the steel product are joined together (Claim 5).
更に、本発明に係る別のアルミ製品と鋼材製品との接合方法は、１枚の鋼板の一部に、対アルミとの密着性に優れる表面処理が施されたアルミ側接合部と、対鋼材との溶接性に優れる表面処理が施された鋼材側接合部とが形成された接合用継ぎ手を用い、前記アルミ側接合部にアルミ製品を一体化せしめ、然る後に前記鋼材側接合部を鋼材製品にスポット溶接又はアーク溶接により一体化することにより前記アルミ製品と鋼材製品とを接合する事を特徴としたものである（請求項６）。 Furthermore, the joining method of another aluminum product and steel product according to the present invention includes an aluminum-side joining part in which a surface treatment excellent in adhesion to aluminum is applied to a part of one steel plate, and the steel product. A steel joint having a surface treated with a surface treatment excellent in weldability is used, and an aluminum product is integrated into the aluminum side joint, and then the steel side joint is made of steel. The aluminum product and the steel product are joined to each other by integrating them with the product by spot welding or arc welding (Claim 6).
前記アルミ側鋼板又はアルミ側接合部にアルミ製品を一体化せしめる手段としては、鋳ぐるみ又はロウ付け又はＭＩＧブレージング接合などを挙げることが出来（請求項７）、アルミ側鋼板又はアルミ側接合部にアルミ製品を鋳ぐるみ一体化する場合、ダイカスト鋳造法或いは低速高圧鋳造法等により鋳ぐるみ一体化することが好ましい。 Examples of means for integrating the aluminum product with the aluminum side steel plate or the aluminum side joint include casting or brazing or MIG brazing joint (Claim 7). When integrating aluminum products by casting, it is preferable to integrate castings by die casting or low-speed high-pressure casting.
また、前記アルミ側鋼板又はアルミ側接合部にアルミ製品を鋳ぐるみにより一体化する場合、鋳ぐるみ時における周辺の雰囲気温度に応じて当該アルミ側鋼板又はアルミ側接合部を予熱するかしないかを判定し、その判定結果に基づいて当該アルミ側鋼板又はアルミ側接合部を予熱することが好ましい（請求項８）。
すなわち、アルミ側鋼板又はアルミ側接合部をアルミ製品で鋳ぐるむ場合に、アルミ側鋼板又はアルミ側接合部を少し暖めておいた方がアルミ製品との密着性が良くなることは知られていたが、特に夏季時の周辺の雰囲気温度が高い時には予熱せずとも期待通りの密着性が得られることを確認し、アルミ製品の鋳ぐるみ時にアルミ側鋼板又はアルミ側接合部を予熱するか否かの温度閾値が外気温に近いことを見出したものである。
In addition, when integrating an aluminum product into the aluminum side steel plate or aluminum side joint by casting, whether or not to preheat the aluminum side steel plate or aluminum side joint according to the ambient ambient temperature at the time of casting. It is preferable to preheat the aluminum-side steel plate or the aluminum-side joint based on the determination result (claim 8).
That is, it is known that when an aluminum side steel plate or an aluminum side joint is cast with an aluminum product, the aluminum side steel plate or the aluminum side joint is slightly warmed to improve the adhesion to the aluminum product. However, especially in the summer, when the ambient ambient temperature is high, confirm that the expected adhesion can be obtained without preheating, and whether to preheat the aluminum side steel sheet or aluminum side joint when casting aluminum products. It has been found that the temperature threshold is close to the outside air temperature.
また、接合用継ぎ手を鋼材製品に溶接する場合、スポット溶接（抵抗スポット）又はアーク溶接（ミグ溶接、ティグ溶接、アークスポット）以外にも、レーザー溶接、プラズマ溶接、摩擦攪拌接合等が可能であるが、その中で一般的に溶接工程で採用されているスポット溶接又はアーク溶接による方法が最も好ましい。 When welding joints to steel products, laser welding, plasma welding, friction stir welding, etc. are possible in addition to spot welding (resistance spot) or arc welding (MIG welding, TIG welding, arc spot). However, the method by spot welding or arc welding generally employed in the welding process is most preferable.
本発明の請求項１に記載のアルミ製品と鋼材製品との接合用継ぎ手によれば、対アルミとの密着性に優れる表面処理が施されアルミ製品と一体化されるアルミ側鋼板と、対鋼材との溶接性に優れる表面処理が施され鋼材製品と一体化される鋼材側鋼板とを溶接により一体化して構成されているので、アルミ製品と鋼材製品との接合用継ぎ手としてアルミ製品に対する密着強度と鋼材製品に対する溶接性とを容易に両立させることが出来る。
よって、アルミ製品と鋼材製品との接合において高い信頼性を得ることが出来る。
According to the joint for joining an aluminum product and a steel product according to claim 1 of the present invention, an aluminum-side steel plate integrated with the aluminum product by being subjected to a surface treatment excellent in adhesion to aluminum, and the steel product Because it is constructed by welding the steel side steel plate that is surface treated with excellent weldability and integrated with the steel product by welding, the adhesion strength to the aluminum product as a joint for joining aluminum product and steel product And weldability to steel products can be easily achieved.
Therefore, high reliability can be obtained in the joining between the aluminum product and the steel product.
しかも、この接合用継ぎ手は、対アルミとの密着性に優れた表面特性を備えたアルミ側鋼板と、対鋼材との溶接性に優れた表面特性を備えた鋼材側鋼板とをそれぞれ別々に形成して溶接により一体化するだけで得られるので、安価に提供することが出来る。 In addition, this joint for joints is formed separately for an aluminum side steel plate with surface characteristics excellent in adhesion to aluminum and a steel side steel plate with surface characteristics excellent in weldability with steel materials. Since it can be obtained simply by welding, it can be provided at a low cost.
また、本発明の請求項２に記載のアルミ製品と鋼材製品との接合用継ぎ手によれば、１枚の鋼板の一部に、対アルミとの密着性に優れる表面処理が施されアルミ製品と一体化されるアルミ側接合部と、対鋼材との溶接性に優れる表面処理が施され鋼材製品と一体化される鋼材側接合部とが形成されているので、請求項１に記載の接合用継ぎ手と同様に、アルミ製品と鋼材製品との接合用継ぎ手としてアルミ製品に対する密着強度と鋼材製品に対する溶接性とを容易に両立させることが可能となる。
しかも、１枚の鋼板の一部に、対アルミとの密着性に優れる表面処理と、対鋼材との溶接性に優れる表面処理を施すだけであるので、より安価に提供することが出来る。
According to the joint for joining an aluminum product and a steel product according to claim 2 of the present invention, a surface treatment excellent in adhesion to aluminum is applied to a part of one steel plate, Since the surface treatment which is excellent in weldability with the steel material and the steel material side joint part integrated with the steel product are formed, the aluminum side joint part to be integrated is formed. Similar to the joint, as a joint for joining an aluminum product and a steel product, it is possible to easily achieve both the adhesion strength to the aluminum product and the weldability to the steel product.
Moreover, since only a surface treatment excellent in adhesion to aluminum and a surface treatment excellent in weldability to steel are applied to a part of one steel plate, it can be provided at a lower cost.
また、請求項３に記載のアルミ製品と鋼材製品との接合用継ぎ手のように、アルミ側鋼板又はアルミ側接合部の表面を溶融亜鉛メッキなどの工法を用いて予め亜鉛合金で被覆することにより、アルミ製品を鋳造するとき、すなわち接合用継ぎ手(のアルミ側鋼板又はアルミ側接合部)がアルミ製品(アルミ鋳物)で鋳ぐるまれる際に、亜鉛被膜とアルミ鋳物が冶金結合することを期待できることから、鋳造金属材であるアルミ製品との接合強度を大幅に向上させることが出来ると共に、亜鉛がアルミより腐食電位が高いことから、鋼板とアルミ製品(アルミ鋳物)との電位差に基づく腐食を防止して耐食性を大幅に向上させることが可能となる。
その結果、自動車の車体やフレーム(鋼材製品)にアルミ製品を接合する場合のように、耐食性要件の非常に厳しい自動車製造等における接合部材にも適用することが可能となる。
Moreover, like the joint for joining the aluminum product and the steel product according to claim 3, by covering the surface of the aluminum side steel plate or the aluminum side joint part with a zinc alloy in advance using a method such as hot dip galvanization. When aluminum products are cast, that is, when the joint for joining (the aluminum-side steel plate or aluminum-side joint) is cast with an aluminum product (aluminum casting), the zinc coating and the aluminum casting are expected to be metallurgically bonded. Therefore, it is possible to greatly improve the bonding strength with aluminum products, which are cast metal materials, and because zinc has a higher corrosion potential than aluminum, corrosion based on the potential difference between the steel sheet and aluminum products (aluminum castings) can be achieved. Therefore, the corrosion resistance can be greatly improved.
As a result, the present invention can be applied to a joining member in automobile production or the like having extremely strict corrosion resistance requirements, such as joining an aluminum product to a car body or a frame (steel product) of an automobile.
そして、本発明の請求項５に記載のアルミ製品と鋼材製品との接合方法によれば、請求項１に記載の接合用継ぎ手を用いて、アルミ側鋼板にアルミ製品を一体化せしめ、然る後に鋼材製品を鋼材側鋼板にスポット溶接又はアーク溶接により一体化することにより前記アルミ製品と鋼材製品とを接合するようにしたので、アルミ製品をアルミ側鋼板に例えば鋳ぐるみにより予め一体化しておけば、既存・既設の接合工程及び設備を変更することなくそのまま利用して、アルミ製品と鋼材製品とを接合組み立てることが可能となる。従って、既存・既設の接合工程及び設備を使用して、既存の接合条件管理レベルでもって製造(接合加工)することができる。 And according to the joining method of the aluminum product and steel material product of Claim 5 of this invention, an aluminum product is integrated with an aluminum side steel plate using the joint for joint of Claim 1, and, so Since the aluminum product and the steel product were joined to each other by later integrating the steel product to the steel side steel plate by spot welding or arc welding, the aluminum product should be integrated with the aluminum side steel plate in advance by, for example, cast-in. For example, it is possible to join and assemble an aluminum product and a steel product by using the existing and existing joining processes and facilities without change. Therefore, it is possible to manufacture (join processing) with existing joining condition management levels using existing and existing joining processes and equipment.
このことは、例えば鋼材製品として鋼材で形成された自動車の車体やフレームに、アルミ製品としてアルミ鋳物で形成された構成部材を接合する工程設備など、ロボット等による自動化が進んでいて組立て工程の設備投資額が大きな工程設備で特に効果的であり、また、アルミ製品を用いた自動車の軽量化を図る上で最大の課題である新規ラインの設置等の投資をする必要がなくなる点においても効果的であり、更に、自動車軽量化設計の自由度も大幅に向上することを意味する。 This means that, for example, process equipment for joining components formed of aluminum castings as aluminum products to automobile bodies and frames formed of steel products as steel products, automation by robots etc. has progressed, and assembly process equipment It is particularly effective for process equipment with a large investment amount, and is also effective in that it is not necessary to invest in the installation of a new line, which is the biggest issue in reducing the weight of automobiles using aluminum products. Furthermore, it means that the degree of freedom in designing a lighter vehicle is greatly improved.
また、本発明の請求項６に記載のアルミ製品と鋼材製品との接合方法によれば、請求項１に記載の接合用継ぎ手を用いて、対アルミとの密着性に優れる表面処理を施したアルミ側接合部にアルミ製品を一体化せしめ、然る後に対鋼材との溶接性に優れる表面処理を施した鋼材側接合部に鋼材製品をスポット溶接又はアーク溶接により一体化することにより前記アルミ製品と鋼材製品とを接合するようにしたので、請求項５に記載のアルミ製品と鋼材製品との接合方法と同様の作用効果を奏することが出来る。 Further, according to the method for joining an aluminum product and a steel product according to claim 6 of the present invention, a surface treatment excellent in adhesion to aluminum is applied using the joint for joint according to claim 1. Aluminum products are integrated into the aluminum side joints, and then the steel products are integrated by spot welding or arc welding into the steel side joints that have been surface treated with excellent weldability to steel. Since the steel product is joined to the steel product, the same effect as the joining method of the aluminum product and the steel product according to claim 5 can be achieved.
更に、本発明の請求項８に記載のアルミ製品と鋼材製品との接合方法によれば、アルミ側鋼板又はアルミ側接合部にアルミ製品を鋳ぐるみにより一体化する場合に、鋳ぐるみ時における周辺の雰囲気温度に応じて当該アルミ側鋼板又はアルミ側接合部を予熱するかしないかを判定し、判定結果に基づいて当該アルミ側鋼板又はアルミ側接合部を予熱するようにしたので、予熱を必要としないと判定された場合には熱処理（予熱）をしなくとも済むので、その分コストダウンを図ることが出来る。 Furthermore, according to the joining method of the aluminum product and the steel product according to claim 8 of the present invention, when the aluminum product is integrated with the aluminum side steel plate or the aluminum side joint part by casting, the periphery at the time of casting It is determined whether or not to preheat the aluminum side steel plate or aluminum side joint according to the ambient temperature, and the aluminum side steel plate or aluminum side joint is preheated based on the determination result, so preheating is required. If it is determined that the heat treatment is not performed, it is not necessary to perform heat treatment (preheating), so that the cost can be reduced accordingly.
以下、本発明の具体的な好適実施例を、図面を参照しながら詳細に説明するが、本発明は図示した実施例のものに限定されるものではない。
図中の符号Ａはアルミ製品を示し、符号Ｂは鋼材製品を示し、符号Ｃ及びＤはそれぞれアルミ製品Ａと鋼材製品Ｂとを接合するための第１発明及び第２発明に係る接合用継ぎ手を示す。
Hereinafter, specific preferred embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the illustrated embodiments.
In the figure, symbol A indicates an aluminum product, symbol B indicates a steel product, symbols C and D indicate joints according to the first and second inventions for joining the aluminum product A and the steel product B, respectively. Indicates.
始めに、図１を参照しながら第１発明に係る接合用継ぎ手Ｃについて説明する。
この第１発明に係る接合用継ぎ手Ｃは、対アルミとの密着性に優れる表面処理が施されてアルミ製品Ａと一体化されるアルミ側鋼板Ｃ1と、対鋼材との溶接性に優れる表面処理が施されて鋼材製品Ｂと一体化される鋼材側鋼板Ｃ2とを溶接により一体化して構成される。図中の符号Ｅは溶接部分を示す。
First, the joint C according to the first invention will be described with reference to FIG.
The joint C according to the first aspect of the present invention has a surface treatment excellent in weldability between an aluminum side steel plate C1 which is subjected to a surface treatment excellent in adhesion to aluminum and integrated with the aluminum product A, and a steel material. The steel material side steel plate C2 that is integrated with the steel product B is integrated by welding. Symbol E in the figure indicates a welded portion.
接合用継ぎ手Ｃを構成するアルミ側鋼板Ｃ1並びに鋼材側鋼板Ｃ2は、どちらも市販されている通常の鋼板材料を用いて、互いに接合されるアルミ製品Ａ及び鋼材製品Ｂに応じて適宜な肉厚及び大きさ形状に形成され、アルミ側鋼板Ｃ1と鋼材側鋼板Ｃ2とは、鋼板同士を溶接する場合に一般的に適用されている例えばシーム溶接により溶接Ｅされる。 Both the aluminum side steel plate C1 and the steel material side steel plate C2 constituting the joint C for joining are made of a commercially available normal steel plate material, and have an appropriate thickness according to the aluminum product A and the steel product B to be joined to each other. The aluminum-side steel plate C1 and the steel-side steel plate C2 are welded E by, for example, seam welding, which is generally applied when welding steel plates.
また、アルミ側鋼板Ｃ1の表面には、対アルミとの密着性に優れる表面処理が施される。すなわち、アルミ側鋼板Ｃ1の表面にアルミ及び鋼材との相性が良い溶融亜鉛被覆処理を施すことにより、当該アルミ側鋼板Ｃ1に対アルミ(アルミ製品Ａ)との密着性に優れる表面特性が付与される。そうすれば、アルミ側鋼板Ｃ1がアルミ製品Ａに鋳ぐるまれる時に、亜鉛合金皮膜がアルミ製品Ａによって一部が溶解し、アルミ製品Ａと亜鉛材が金属結合し、結果としてアルミ側鋼板Ｃ1と鋳造アルミ製品Ａとが強固に接合される。 Further, the surface of the aluminum-side steel plate C1 is subjected to a surface treatment that is excellent in adhesion to aluminum. In other words, the surface of the aluminum side steel plate C1 is subjected to a hot dip galvanizing treatment that has good compatibility with aluminum and steel materials, so that the aluminum side steel plate C1 has surface characteristics excellent in adhesion to aluminum (aluminum product A). The Then, when the aluminum side steel plate C1 is cast on the aluminum product A, the zinc alloy film is partly melted by the aluminum product A, and the aluminum product A and the zinc material are metal-bonded, resulting in the aluminum side steel plate C1. And the cast aluminum product A are firmly joined.
また、鋼材側鋼板Ｃ2の表面には、対鋼材(鋼材製品Ｂ)との溶接性に優れる表面処理が施される。すなわち、鋼材側鋼板Ｃ2の表面を合金化亜鉛めっき処理するか又は素地面とすることにより、当該鋼材側鋼板Ｃ2に対鋼材(鋼材製品Ｂ)との溶接性に優れる表面特性が付与される。 Further, the surface of the steel material side steel plate C2 is subjected to a surface treatment excellent in weldability with a steel material (steel product B). That is, the surface property of the steel material side steel plate C2 excellent in weldability with the steel material (steel product B) is given to the steel material side steel plate C2 by subjecting the surface of the steel material side steel plate C2 to alloying galvanization or using a bare ground.
而して、この第１発明に係る接合用継ぎ手Ｃを用いてアルミ製品Ａと鋼材製品Ｂとを接合する場合には、事前に、対アルミとの密着性に優れる表面処理が施されたアルミ側鋼板Ｃ1と、対鋼材との溶接性に優れる表面処理が施された鋼材側鋼板Ｃ2とを、シーム溶接等により溶接Ｅして一体化しておき、次にアルミ側鋼板Ｃ1にアルミ製品Ａを一体化せしめる。 Thus, when the aluminum product A and the steel product B are joined using the joint C according to the first invention, the surface-treated aluminum having excellent adhesion to aluminum is applied in advance. The side steel plate C1 and the steel material side steel plate C2 which has been subjected to a surface treatment excellent in weldability with the steel material are integrated by welding E by seam welding or the like, and then the aluminum product A is attached to the aluminum side steel plate C1. Integrate.

When casting into a predetermined product shape, the aluminum side steel plate C1 of the joint for joint C is set (inserted) in a casting mold (die) so that the aluminum side steel plate C1 of the joint for joint C is cast with the aluminum product A. The whole body is integrated.
At that time, it is determined whether or not to preheat the aluminum side steel plate or the aluminum side joint according to the ambient temperature at the time of casting, and based on the determination result, the aluminum side steel plate or the aluminum side joint is preheated. It is preferable. Then, preheating is not necessary when the ambient temperature in the summer is high.
然る後に、一方(アルミ側鋼板Ｃ1)にアルミ製品Ａが一体化された接合用継ぎ手Ｃの他方(鋼材側鋼板Ｃ2)を、鋼材製品Ｂにスポット溶接又はアーク溶接により溶接Ｆして一体化する。これにより、アルミ製品Ａと鋼材製品Ｂとが、接合用継ぎ手Ｃを介して一体的に接合される。 After that, the other joint (steel material side steel plate C2) of the joint C in which the aluminum product A is integrated on one side (aluminum side steel plate C1) is integrated by welding F to the steel product product B by spot welding or arc welding. To do. Thereby, the aluminum product A and the steel product B are integrally joined via the joint for joint C.
なお、接合用継ぎ手Ｃの鋼材側鋼板Ｃ2を鋼材製品Ｂに接合する場合、ロウ付け、半田付け、スポット溶接（抵抗スポット溶接）、アーク溶接（ミグ溶接、ティグ溶接、アークスポット）、レーザー溶接、プラズマ溶接、電子ビーム溶接、摩擦撹拌接合、リベット/ネジによる接合、カシメによる接合、摩擦嵌合による接合など、既存の溶接工程で通常に用いられている接合法を適用することが出来るが、その中でも、スポット溶接（抵抗スポット溶接）、アーク溶接（ミグ溶接、ティグ溶接、アークスポット）が好ましい。 In addition, when joining the steel side steel plate C2 of the joint C for joining to the steel product B, brazing, soldering, spot welding (resistance spot welding), arc welding (MIG welding, TIG welding, arc spot), laser welding, The welding methods commonly used in existing welding processes such as plasma welding, electron beam welding, friction stir welding, rivet / screw joining, caulking joining, and friction fitting joining can be applied. Among these, spot welding (resistance spot welding) and arc welding (MIG welding, TIG welding, arc spot) are preferable.
