Optical fibers are welded together by positioning the end parts in vacuum chucks 10 and 11. Piezo-electric elements 8 force the chucks towards one another. The piezo-electric elements are put into operation by the power supply of a welding arc operating between the chucks. The heated fiber end parts are thus moved together to ensure a good welded joint.
