Abstract

In this paper, SiC particle reinforced aluminum metal matrix composite (SiCp/Al MMC) is welded with high power continuous wave CO₂ laser. Microstructure of the laser beam welded SiCp/Al MMC is characterized as functions of laser processing parameters (laser power density, welding speed, shielding gas flow direction, etc.). Results show that sound weld with few porosity can be produced by laser beam welding, while needle-like aluminum carbide is formed in the weld. The size and volume fraction of aluminum carbide are proportional to the laser power density. Direction of shielding gas flow has significant effect on weld surface quality and weld microstructure.
