New Method for Dissimilar Metals Joining of Steel Sheet and Aluminum Alloy Using Resistance Spot Welding and Dimple Shape, Dimple Spot Welding (DSW)

抵抗スポット溶接とダボ形状を用いた鋼板とアルミニウム合金の 新しい異種金属接合法

In order to advance multi-materialization of automotive body structure, the authors developed a new dissimilar metal joining method of steel and aluminum alloy sheet named Dimple Spot Welding (DSW). DSW has a laminated structure of Fe-Al-Fe, and is a welding method of dimple and backing plate. As a result of tensile shear tests and cross tensile tests using steel and aluminum specimens joined by DSW, the following results were found out: 1) Joining strength of DSW depends on combination of dimple height of steel sheet, and hole diameter of aluminum alloy sheet. 2) Bonding strength of DSW was equal to or higher than that of conventional mechanical joining methods such as SPR, FDS®, Clinching, and so on.鋼板とアルミニウム合金の異種金属接合は車体のマルチマテリアル化に求められる技術である．筆者らは，ダボ形状と抵抗スポット溶接を用いた鋼板とアルミニウム合金の新たな接合工法を開発した．本工法で接合した試験片で引張せん断と十字引張試験を行った結果，従来の機械的接合法と比べて同等以上の接合強度を示すことを確認した．
