    摘要： Disclosed is a bonding method for dissimilar materials made from metals and its resulting structures. The materials to be bonded are formed by layering three or more sheets such that a dissimilar material interface and a same material interface are formed. A first current is conducted between a three-sheet layered plate material wherein an aluminum alloy plate, a zinc plated steel plate and a bare steel plate, for example, are layered in order. A nugget is formed in an interface between the zinc plated steel plate and the bare steel plate, which are the same materials. Then, a second current greater than the first current is conducted, and a nugget is formed in an interface between the aluminum alloy plate and the zinc plated steel plate.

    摘要： Embodiments of the present invention provide a data group for each parameter that is classified into a first group and a second group, based on the performance of the products, a base point of a distribution of the data group is calculated, based on the distribution, and a distance range from the base point is decided. The number of data within this range belonging to the first group is counted and substituted for variable FX, the number of data belonging to the second group is counted and substituted for variable SX, the number of data outside this certain range belonging to the first group is counted and substituted for variable FY, and the number of data belonging to the second group is counted and substituted for variable SY. Moreover, a failure content ratio is calculated from variables FX, FY, SX and SY, and the yield impact is calculated.
