Laser texturization to improve absorption and weld penetration of aluminum alloys
Source abstract
Abstract
In the present work, laser texturization treatments have been performed for the first time on aluminum alloys to increase their absorption and weld penetration. Adjusting the experimental conditions, laser texturization increases the roughness and decreases the diffuse and specular reflectance of surfaces. The textured samples were subsequently subjected to bead-on-plate laser weld treatments with a high power diode laser. Taking the weld beads of sandblasted samples as reference, depth improvements percentages around 20% are reached in some textured samples. Laser texturization has demonstrated to increase the weld penetration ability of aluminum alloys, constituting a potential tool to reduce the energetic requirements of the laser welding process.
