Abstract

The possibilities of pulsed laser welding of aluminium alloys monitoring are investigated. Simple finite element modeling of conduction and keyhole welding has been carried out. A complete instrumentation has been set up, including beam and plasma monitoring and impact shape and size measurements. This set up enables a real time monitoring of the seam and the detection of critical defects.
