A recently granted patent (Publication Number: US11897046B2) discloses a welding apparatus designed for precision welding applications. The apparatus comprises first and second guide rails with a carriage that moves along them, depositing feedstock material on the welding target. An ultrasonic weld head attached to the carriage engages the deposited material with ultrasonic vibrations for welding. Additional guide rails can be connected to form a rectangular frame, and a rail follower assembly ensures smooth movement along the rails. The apparatus also includes mechanisms for welding force enhancement and precise movement control, with a processor providing instructions for a predetermined two-dimensional welding path.

The patent claims cover various aspects of the welding apparatus, including the attachment of guide rail supports to the welding target surface, the use of rail segments to form a continuous circumferential ring for cylindrical welding targets, and the application of metal tape as feedstock material. The apparatus is versatile, allowing for different welding configurations and precise control over the welding process. With features like ultrasonic welding and movement control mechanisms, this patented welding apparatus offers a sophisticated solution for high-quality welding applications.
