VERFAHREN ZUM ZUSAMMENSCHWEISSEN ENDLOSER METALLBAENDER

摘要

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 DEG , from the axis of the drum.
