    • To provide a joint product of a steel product and an aluminum material, and a spot welding method for the joint product, ensuring that spot welding with high bonding strength can be performed. In one embodiment, a steel product 1 having a sheet thickness t1 of 0.3 to 3.0 mm and an aluminum material 2 having a sheet thickness t2 of 0.5 to 4.0 mm are joined together by spot welding to form a joint product of a steel product and an aluminum produce. In this joint product, the nugget area in the joint part is from 20×t20.5 to 100×t20.5 mm2, the area of a portion where the thickness of the interface reaction layer is from 0.5 to 3 μm is 10×t20.5 mm2 or more, and the difference between the interface reaction layer thickness at the joint part center and the interface reaction layer thickness at a point distant from the joint part center by a distance of one-fourth of the joint diameter Dc is 5 μm or less. According to this construction, there can be provided a dissimilar material joint product with excellent bonding strength, which can be formed by an existing spot welding apparatus at a low cost without newly using other materials such as clad material or without newly adding a separate step, and a spot welding method for the dissimilar material joint product.
    • 为了提供钢材和铝材的联合产品,以及用于接合产品的点焊方法,确保可以执行高粘合强度的点焊。 在一个实施例中,通过点焊将片材厚度t1为0.3〜3.0mm的钢制品1和板厚t2为0.5〜4.0mm的铝材2接合在一起,形成钢材和 铝制品。 在该接合部中,接合部的熔核面积为20×20.5〜100×20.5mm 2,界面反应层的厚度为0.5〜3μm的部分的面积为10×20.5mm 2以上, 并且在接合部中心的界面反应层厚度与远离接合部中心的点的界面反应层厚度之间的差为接合直径Dc的四分之一的距离为5μm以下。 根据这种结构,可以提供一种具有优异接合强度的不同材料接合产品,其可以通过现有的点焊装置以低成本形成,而不需要重新使用诸如包覆材料的其它材料,或者不新增单独的步骤, 以及用于异种材料接合产品的点焊方法。
