METHOD FOR ULTRASOUND WELDING AND CONSTRUCTION MODULE, PARTICULARLY DOOR MODULE OF A MOTOR VEHICLE

摘要

The invention relates to a method for ultrasound welding of a first and a second component, whereby the first component contains a recess for the reception of first and second protrusions of the second component, with the following steps: Positioning of the first and the second components so that the first and second protrusions protrude into the recess and touch a floor of the recess, Transmission of an ultrasound oscillation for the generation of a relative movement between the first and the second components, whereby the floor is pressed against the first and second protrusions, so that first protrusion is deformed in a first direction and second protrusion in a direction opposite to the first direction, and that at least a first welding connection between the first protrusion and the floor and a second welding connection between the second protrusion and the floor are formed.
