Weld assembly for ultrasonic additive manufacturing applications

This invention describes an attachment that transforms a standard milling machine into a device for building up metal parts layer by layer using ultrasonic vibrations. The attachment, which includes an ultrasonic welding head, fits onto the machine's rotating spindle like a regular milling tool. A special collar within the attachment ensures that the strong forces generated during the welding process are safely transferred to the machine's sturdy vertical axis without causing damage. The claims narrow the invention to using metal foil tape as the building material.

Why it matters: Since 2014, advancements in modular machine design and sophisticated CNC control systems could make integrating this specialized weld assembly onto existing milling machines more straightforward and precise.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedUltrasonic weld head, custom collar, precision machining
