Patent ID: 7012216

Claim:
A hand-held laser fusion welding assembly, comprising: a main body dimensioned to be grasped by a hand and adapted to couple to a laser delivery system, a gas supply system, and a coolant supply system, the main body having an internal gas flow passage and one or more coolant flow passages extending therethrough; and a nozzle releasably coupled to a first end of the main body, the nozzle having at least an aperture in fluid communication with the internal gas flow passage through which laser light from the laser delivery system and gas from the gas supply system may pass; an end cap releasably coupled to a second end of the main body, the end cap including: an optical cable opening adapted to receive an optical cable, a gas flow passage in fluid communication with the main body gas flow passage, and one or more coolant flow passages each in fluid communication with one of the main body coolant flow passages; one or more filler media delivery flow passages extending through the main body; and one or more filler media delivery flow passages extending through the end cap, each end cap filler media delivery flow passage adapted to receive a filler media therein, and each in fluid communication with one of the main body filler media delivery flow passages.
