Evaluation of Basic Laser Welding Capabilities
Abstract
5456 AND 5086 ALUMINUM ALLOYS WERE WELDED WITH A CONTINUOUS, CROSS- BEAM CO2 laser operated in the master oscillator/power amplifier mode (Gaussian beam). Extensive experimental parameter modifications were made to the welding apparatus in an attempt to improve weld quality, in particular the reproducibility and uniformity of fusion zone penetration. The effects of laser (power, mode, optics), process (welding speed, beam rotation, shielding design) and other (weld prep, wire feed, flux, backup, etc.) parameters on weld performance were evaluated. Although some progress was demonstrated, the capability for generation of sound autogenous laser weldments in these alloys on a reproducible basis was not established within the scope of this program. Areas of endeavor which might be expected to produce further significant improvement in the ability to laser weld 5000 series aluminum alloys are not evident at this time.
