Abstract
For tube welding, use is made of a locator element intruding into the tube and running with the tube, to position the edges of the tube-round ahead of the welding point with its laser beam ( ). The running locator element has a plurality of stops ( ) arranged on a driven revolving chain ( ). Forming elements ( ′) act on the outside of the tube-round to position the edges. A precise edge-positioning for welding, in particular for tube welding, can thus be achieved.
