Abstract

Two workpieces (30, 40) are connected by means of ultrasound. This is firstly achieved by providing a second workpiece (40) and a workpiece (30) having at least one energy director (31). The workpieces are brought into contact with one another so that the energy director (31) is in contact with a first surface (41) of the second workpiece (40). Ultrasonic vibrations are then introduced into one of the workpieces (40) via a working surface (11) of a sonotrode (10). The contour of the sonotrode (10) used has a contact line (12) on the working surface (11). The sonotrode (10) is positioned relative to the first workpiece (30) in such a way that the contact line (12) extends transversely to the energy director (31).
