Patent ID: 7307237

Claim:
A hand-held laser fusion welding assembly, comprising: a main body dimensioned to be grasped by a hand and adapted to couple to, and receive laser light from, a laser delivery system, the main body having at least a first end and a second end and an internal feeder material supply passage extending therethrough; and a nozzle assembly coupled to the main body and including: a nozzle disposed adjacent the main body first end and including an inner surface that defines a laser passage, and a feeder material supply passage extending therethrough, the nozzle laser passage having an aperture through which the laser light from the laser delivery system may pass, the nozzle feeder material supply passage in fluid communication with a main body feeder material supply passage, laser extension tip coupled to the nozzle laser passage aperture and extending therefrom, the laser extension tip having an inner surface that defines a laser passage through which the laser light that passes through the laser passage aperture may pass, and a filler media extension tube coupled to the nozzle and extending therefrom, the filler media extension tube having an inner surface that defines a filler media passage in fluid communication with the nozzle filler material supply passage.
