Abstract
The invention relates to an ultrasonic welding device comprising a sonotrode (14) transmitting ultrasonic vibrations and an anvil (15) disposed on an anvil carrier (17), the anvil (15) being disposed on the anvil carrier (17) in an exchangeable manner so that an mounting surface (21) of the anvil (15) rests against a support surface (22) of the anvil carrier (17) by means of a normal force exerted by a pretensioning device, the mounting surface (21) of the anvil (15) having a surface hardness greater than the surface hardness of the support surface (22) of the anvil carrier (17), the mounting surface (21) having a surface structure at least in the area of a partial surface, and the mounting surface (21) having a surface roughness of Rz/Ra≥2 at least in the area of the partial surface.
