Multispot Laser Welding System for Car Body Assembling 982393
As the automotive industries require new cost efficacy and high quality assembly systems, COMAU, in cooperation with Centro Ricerche Fiat, is developing a car body laser welding production device based on the Nd:YAG multifibre concept.
The laser welding system is composed by an high power Nd:YAG laser source, a modular beam distributor operating with short switching time, a series of fibres and focusing heads integrated with the assembly device; a special device to monitor the quality of the spot is integrated inside the laser system.
A modular optical multiplexer system and innovative focusing optics, suitable for different laser spot shapes, have been developed.
An example of application on a car body sub-assembly is given and preliminary results of the investigation are presented.
