ABSTRACT:
A process for welding including providing sheet material comprising a thermoplastic polymer, overlapping edges of the sheet material to form a lap joint, supporting the lap joint on an anvil, and welding the lap joint by contacting and traversing the lap joint with an ultrasonic welding horn, the improvement comprising initially contacting and traversing the lap joint with the welding horn at a first predetermined traverse rate and thereafter increasing the first traverse rate to a second higher predetermined traverse rate.
