A technique and a tool for ultrasonic welding by pressing a connecting element into a constant gap is proposed. The welded joints of plates arranged parallel to each other prove to be consistent in terms of strength and transparency. It is established that the coefficient of concentration of energy released per unit of volume of the parts being welded greatly depends on the contact area between them. When designing a welded seam, it is necessary to ensure edge preparation to reduce the contact area between the welded parts. In the case of a V-shaped protrusion in the design, the angle at its top should be approaching 90. The optimal technological parameters for ultrasonic welding by pressing into a constant gap are determined.
