1. An ultrasonic welding system comprising:
a support structure configured for supporting a workpiece;
a weld head assembly including an ultrasonic converter carrying a sonotrode; and
a conductive pin supply configured to provide a plurality of conductive pins for welding using the sonotrode,
wherein the sonotrode of the weld head assembly is configured to withdraw a conductive pin from the conductive pin supply, and the weld head assembly is configured to carry the withdrawn conductive pin towards the workpiece, and to ultrasonically weld the conductive pin to the workpiece, wherein the sonotrode defines a vacuum channel for withdrawing the conductive pin from the conductive pin supply.
