Individual solutions for an extensive range of tasks
Laser welding is suitable for diverse areas and diverse applications. To be able to provide the optimum solution for everyapplication, Leister has developed various concepts. In this way the potential of this process can always be applied
profitably. Leister offers systems for contour welding and simultaneous welding, as well as for radial welding. The range
is extended through the mask and GLOBO welding concepts that were distinguished with the Swiss Technology Award.
Contour welding Simultaneous welding Radial welding In contour welding, a laser spot is guidedsequentially along a predetermined wel-ding pattern, melting it locally. The wel-
ding volume remains comparatively small
as a result of the geometric conditions,and extrusion of the melt is avoided.Relative motion, is achieved by movingthe component, the laser, or a combinati-onof both. In this technique, one or more
industrial lasers heatthe entire weld path simultaneously. Highpower
industrial diode lasers are generally used as a
result of their compact design. It is very easy
to achieve linear welding seams. Almostanybeam geometry can be generated by meansof special, state-of-the-art beam shaping
elements. A unique method for bonding cylindricalcomponents whereby a mirror deflects thelaser beam such that it impinges radially on
the outside symmetrical surface of the com-
ponent. The tight fit between the joiningparts ensures the clamping pressure requiredfor the welding process. The component
remains in a fixed position during the cir-cumferential, continuous welding process. Characteristics and application: Characteristics and application: Characteristics and application:
