Abstract

A pilot 3D-laser machining system for combined laser beam cutting and welding of complex tube geometries with small diameters ((phi) < 20 mm) was developed. It consists of a pulsed Nd:YAG-laser, rated 500 W, two fiber beam deliveries each equipped with a special working head, a tool changing system, an articulated robot, a turn table and the necessary clamping systems all housed in a protection cabin. A processing strategy was developed resulting in subsequent oxidefree cutting and welding in one clamping device to reach the tolerable gap widths for laser welding without filter material. The system performance was evaluated concerning repeatability, reliability and laser safety. The performance of laser manufactured workpieces show a better quality than those produced by conventional welding. Economical aspects are given in comparison to conventional welding.
