France-based Cailabs’ Canunda-HP laser welding head is for submillimeter ring beam shaping at powers up to 16 kW. The company’s MPL1C1 technology is relevant for laser welding because it can achieve high-quality ring beam shaping that achieves a weld without projections. It can also maintain high power to weld very thick or complex materials, such as copper. The developed laser head has been used in a conventional industrial environment and can be used on a robot arm. The head is compatible with accessories, such as a shielding gas supply, on-axis alignment camera and process control sensors.
