Abstract
This chapter is aimed at determining the melting efficiency of aluminum alloy 5083 during CO2 laser welding process. Theoretical models were used for the melting efficiency determination as proposed by other investigators which also included an examination of the fluid flow pattern of the alloy. The results obtained indicate that the acceptable melting efficiency calculated was 38%. This value compares well with and falls within the range of other values reported in other literature. The theory of metal melting as it relates to laser welding depends on the thermal state of the material under investigation. Applying high laser power under a controlled environment would achieve deeper penetration with fewer heat affected zones; therefore a deep understanding of the chemo-physical properties of a metal is required to determine its melting efficiency and these properties have been adequately treated in this study.
