Abstract : Design, development, and construction of the 25kilowatt spot-type ultrasonic welding machine continued. Emphasis was placed on performance evaluations of both the modified tension-shell ceramic transducer and the single-element example of the overhung-coupler geometry with its present mechanically replaceable welding tip. Liaison efforts associated with expediting delivery of the motor-alternator power source were conducted, and control system components were incorporated into the welder frame. The fourwafer unbonded ceramic transducer was driven at its design power (a maximum of 3.4 kilowatts) without the former arc-over difficulties, and there was no evidence of untoward unit or circuitry failure.
