Abstract


The interaction between a high-density laser beam and a metallic surface produces a deep and narrow melted area that has a characteristic keyhole geometric pattern. The amount of energy absorbed by the metal will depend on the parameters of the laser beam being applied, and the nature and geometry of the piece. In this paper, a formulation is presented which makes it possible to quantitatively determine the amount of energy absorbed by the metal as a function of a series of experimental parameters. The formulation that has been developed is especially applicable in beadon-plate tests commonly used to analyze laser-metal interactions in laser technology research. The formulation applies specifically to two types of aluminium alloys, Al-Mg-Si and Al-Zn-Mg.
