ABSTRACT:
An ultrasonic welding tip assembly and associated method of use are described. The welding tips of the assembly may be conical with the cone height A and base width B having a ratio of A/B=1.2 or frusto-conical with a ratio of 0.76 in preferred embodiments. The welding tips are supported on anvils. In the welding process, the tips are only partially inserted into the material being welded so that the anvils remain spaced from the material. This space provides a reservoir into which molten material may flow away from the regions of the welding tips.
