Welding method of eyeglasses of titanium and shape memory alloy using YAG laser welding

摘要

The present invention relates to titanium, and shape memory frames welding method of the alloy material using the YAG laser, in particular high melting point material is titanium and the shape memory alloy structure to improve performance at the time of welding the frames using a laser has, as well as a large amount of the preparation production, by simply supplying power to the welder and at the same time can be effectively applied in all economic aspects such as production cost, regardless of the skill level of the laser welder is to be transmitted to the optical fiber precision welding.; A titanium frames for producing a laser welding apparatus used in the present invention, YAG laser oscillator 1, simultaneous branch (2), the optical fiber 3, the protection gas box 4, the optical coupler 5, a weld monitoring unit ( blood in 6), blood weldment is Dongda 7 and the cylinder (8) consists of a laser welding for titanium frames are YAG laser oscillator 1 of the laser to protect the gas box 4, sent to the optical fiber 3 from an optical coupler (5) was used to precisely focus on the weldment maethi. The position of the blood weldment is determined by using a diode laser via a CCD camera of a maethige focus on the material of the blood, and then weld the welding monitoring unit (6).
