Each beam (24,30) is directed into one end of a different lightguide fiber (36,38) having equal lengths so as to pass therethrough. The opposite ends of the fibers (36,38) are located proximate inner and outer sleeves (12 and 14) which are simultaneously spot welded at a plurality of sites by the beams exiting the fibers.
