High Power CO_2Laser Welding of Al_2O_3 Ceramics
Search this Article
The welding characteristics of 87% Al_2O_3 were investigated using a high power CO_2 laser, and it was found that full penetration welding of 20mm thick specimens is possible at a welding speed of 400mm/min and a laser power of 10kW. A sound bead was obtained with full penetration of specimens up to 10mm at a suitable laser power and welding speed. The joint efficiency was about 60% for full penetration welding of a 4mm thick specimen with the base material.
