Method for welding the ends of tubular containers filled with a pourable medium, in particular tubes, made from a thin-walled flat material which can be softened or melted through heat, wherein the tubular container is held in such a fashion that the end which is to be welded is accessible and the tubular container is heated at the accessible end in a peripheral region to a temperature which allows welding thereof, and the heated end is pressed together along an elongated welding seam transverse to the longitudinal extension of the container, wherein the tubular container is stationary and a laser beam is directed, via a deflection element positioned outside of the tubular container, onto the inner wall of the tubular container, and the deflection element is set into rotation for heating the peripheral region. |
