Simultaneous ring

Using an axicon and focusing lens, rings of different diameters and line widths can be generated from a laser beam to weld a ring contour in one shot.

With simultaneous welding the entire contour melts and plasticizes at the same time. A welding rib can be melted down for process control or to bridge tolerance gaps between the two parts.

The ring-shaped beam is also the basis for simultaneous circumferential welding with the radial optics.
