A method is disclosed for welding coiled metal bands together in a rotatable drum. An energy beam is introduced from an energy beam generator arranged stationary outside the drum coaxially into the interior of the drum. The energy beam is directed to a predetermined weld area by deflecting the energy beam at least once transversely, preferably at an angle of about 90.degree., from the axis of the drum.

Method of welding metal bands together

A method for fastening optical and electro-optical components characterized by the component being fixed either individually to a base member or another component by being secured by laser welding. Preferably, the component is either secured directly to a weldable support member or to an intermediate carrier which in turn is connected to a weldable support member and the support member is then welded to a base member by the laser welding.
