Experimental observation of keyhole shapes in the laser welding of aluminum blanks

A camera-based in situ monitoring system for the Nd:yttrium–aluminum–garnet laser keyhole welding process of aluminium has been developed. The use of an external illumination source for image formation decouples the performance of this system from many process parameters. A prototype of the monitori...
