In the design and strength analysis of a spot welded structure, the mechanical property of spot weld, and the number, spacing or arrangement, etc. of spot welds in a joint are considered as the primary factors. However, elastic deformation of weld, that is displacement coefficient, which is one of the mechanical properties of spot weld is not sufficiently applied because the characteristics have not been made clear. This report deals with the relationship between the displacement coefficient value and the quality of spot weld, the influence of joint type, etc. in a mild steel spot welded joint. As the result of the investigation, it is found that the displacement coefficient value of mild steel spot weld is smaller than those of aluminum alloy and riveted joint of same size, and there is hyperbolic relationship between the displacement coefficient value and the nugget diameter of spot weld and so on. Moreover, the application of displacement coefficient to spot welded structure design is studied. And, it is shown with some examples that the displacement coefficient is applicable to analysis of torsional rigidity and calculation of load share of spot weld in a spot welded structure.
