Laser welding: the technology
During laser welding, the laser heats the material to melting temperature. The beam is focused by means of optics. The weld seam is created by the relative motion between the laser beam and the workpiece.
To protect the weld surface against oxidation, argon is used as a shielding gas during the process.
Automated laser welding
KUKA provides individual solutions and all types of production technology for laser welding. This ranges from the modular robotic cell to the fully-automated system – also in conjunction with other joining technologies, such as bonding and sealing or spot welding.
A remote laser welding head, in combination with our robot controller, optimizes path configuration “on the fly”. The three-dimensional mobility of the laser beam increases utilization of the robot and minimizes the time between welds.
Shorter product life cycles are becoming ever more common in the age of Industrie 4.0. The KUKA flexibleCUBE laser is ideal for a dynamic production setting. The compact welding cell can be upgraded or converted in a very short space of time.
Laser welding: the advantages
The primary advantages of laser welding are:
- Low unit costs thanks to high process speeds and reduced reworking
- High degree of reliability due to non-contact, force-free processes and wear-free tools
- Outstanding quality due to high welding depths and narrow seams
