In this paper, the experiments of cutting titanium alloy sheet with Nd:YAG pulsed laser were carried out and the effects of the type of shielding gases, gas pressure and laser parameters on kerf width, surface quality and metamorphic layer thickness were studied. The results showed that compressed air is suitable for laser cutting of titanium alloy, the Argon gas does better, while Oxygen gas has undesirable effects; the metamorphic layer is thicker with compressed air as assisted gas in comparison to that with Argon gas; the kerf width increases as the power density, pulse frequency and pulse width increase; higher cutting speed can be applied and the cutting quality is improved when the pulse frequency is increased.
