摘要：The present invention is directed to a method and apparatus using a light guidefor directing a laser beam to a weld zone. The light guide includes an entrance end, anexit end and a flexible body therebetween. The entrance end of the light guide is

operatively coupled to a laser source such as a diode and is adapted to receive andcommunicate the laser radiation through the light guide. The light guide is formed of aflexible material to permit the exit end of the light guide to be spaced from and alignedwith complex two-dimensional and three-dimensional weld zone configurations. Theinternal reflection of the light guide contains the laser radiation therein as it passes fromthe entrance end and through the exit end of the light guide. The light guide andcorresponding methods of welding parts permit laser welding of complex geometricconfigurations.
