Paper Abstract

In this study, a statistical analysis was carried out about influences of energy variance, pre-pulse and post-pulse setting to the main pulse on the melt zone. In the experiment, laser beams were irradiated on the plates of aluminum alloy by two spots, and then, depth and width of melt were measured. Thus, the fluctuation in the dimensions measured was analyzed using statistical methods.
