Let us consider the simplest scheme of ultrasonic spot welding, illustrated in Fig. 1. Shown in the figure are the end of the rod* (1), which is set in vibration by a power source located above it; the welding tip (2), which vibrates with amplitude ξ0, the plates† to be welded (3 and 4) (plate 3, which is in contact with the tip 2, will be referred to hereinafter as the “upper workpiece,” although it is possible to have a different welding arrangement in which the tip 2 and workpiece 3 are situated below. so that Fig. 1 is then rotated in the plane through 180° about the point A); the support tip (5); the support (6). The plates 3 and 4 are pressed between the tips 2 and 5 with a constant force N. We shall also make use of the ratio σ = N/St, where St is the area of the impression of the welding tip on the workpiece.
