Abstract

The modulation and duty cycle effects on Al-alloy welding with high power Nd-YAG laser are investigated. Micro- structural characterization of the low and high duty welds with wave modulation identified the differences in the weld morphology. Welding depth, undercut and strength of fusion zone are discussed as a function of the processing parameters.
