With this Leister patented technique a mask is inserted between the laser sources and the parts to be welded. A curtain or collimated laser beam is moved across the entire joining area of the parts. The laser beam is only incident on the components where they are not obscured by the mask.

A unique method for bonding cylindrical components whereby a mirror deflects the laser beam such that it impinges radial on the rotational symmetric surface of the component. The tight fit between the joining parts ensures the clamping pressure required for the welding process. The component remains in a fixed position during the circumferential, continuous welding process.

Globo welding works along the lines of contour welding. A laser beam is focused at a point on the joining plane via an air bearing, frictionless, freely rotating glass sphere. It also serves as a mechanical clamping tool. The glass sphere replaces the mechanical clamping device and expands the scope of laser welding continuous and 3-dimensional applications.
