Abstract
An ultrasonic welding apparatus (50) includes a sonotrode (8) with a working surface (10), an anvil (4) with a working surface (11), which lies opposite the working surface (10) of the sonotrode (8), and two side delimiters (5, 6) with respective side delimiting surfaces (12, 13). The working surfaces (10, 11) and the side delimiting surfaces (12, 13) delimit a compression chamber (9) for placing an elongated welding material (60) in a welding material direction (B). The ultrasonic welding apparatus (50) has a clamping device (14), by which the anvil (4) is clamped at least in a welding position (S) by a clamping force, which acts on at least part of a side (15) of the engaging surface (26) of the anvil (4) that lies opposite the working surface (11) of the anvil (4), in the direction of the sonotrode (8). A method for ultrasonic welding is also disclosed.
