Abstract

In this work bead-on-plates tests have been performed with CO₂ laser beam, on Al-Mg-Si and Al-Zn-Mg aluminium alloys with different surface treatments. Al-Mg-Si alloy has presented more energy absorbed and best surface finish. The surface treatment with paints has produced an increase of absorbed energy, but with an important porosity in the fusion zone. The increase of surface rugosity has produced an increase of absorbed energy. The chemical treatments previous at bead-on-plates test have produced an important increasing in absorbed energy, especially in Al-Mg-Si alloy.
