Laser welding the porous and compacted titanium components

摘要

The process of laser welding of porous powder metallurgical titanium parts with each other and with compact titanium parts was investigated. The welding was carried out by Nd:/AG pulse-periodic laser (#lambda#=1.06 #mu#m). It was shown that preliminary mechanical treatment of porous surfaces improves the quality of the weld. It was established that high-quality weld can be fabricated due to laser welding which is executed without use of shielding gas medium and adding materials. The optimum conditions of welding process were determined.
