1. A device for ultrasonic welding of composite material comprising
at least two tools for ultrasonic welding comprising a sonotrode and an anvil,
wherein each tool has a functional surface for contact with the material to be welded,
wherein the functional surfaces of the tools are aligned approximately parallel to one another such that a gap with an approximately horizontal seam direction is created between the functional surfaces,
wherein the tools are mounted in such a way that the width of the gap can be changed by moving at least one of the tools along a feed direction,
at least one joint with at least one axis of rotation about which one of the tools can be rotated, and
wherein the position of the axis of rotation can be changed,
wherein the position of the axis of rotation can be displaced along the seam direction and the displaceability is achieved in that the joint can be displaced relative to the rest of the device and can be locked in different positions.
