Abstract

The invention discloses a molten pool plasma radiation spectrum acquisition mechanism. The molten pool plasma radiation spectrum acquisition mechanism comprises a laser auxiliary centering assembly and a fiber probe clamping adjustment assembly which are arranged with an interval, wherein the laser auxiliary centering assembly comprises a laser emitter, through sliding, a center of the laser emitter and a weld surface of a workpiece are coplanar, the laser emitter is used for emitting laser to the fiber probe clamping adjustment assembly, the laser is reflected on the fiber probe clamping adjustment assembly to form a laser red spot, the fiber probe clamping adjustment assembly comprises a fiber probe, the fiber probe slides for a corresponding distance on the basis of the position of the laser red spot, so a center of the fiber probe, the weld surface and the center of the laser emitter are coplanar. The invention further relates to a laser welding device equipped with the molten pool plasma radiation spectrum acquisition mechanism.

Description

technical field [0001] The invention belongs to the related field of laser welding, and more specifically relates to a melting pool plasma radiation spectrum collection mechanism and a laser welding device having the melting pool plasma radiation spectrum collection mechanism. Background technique [0002] In the machinery and equipment manufacturing industry, laser welding relies on its technical advantages such as precise control of welding energy, small heat-affected zone and thermal deformation, high welding speed, and large weld pool depth. , aerospace, energy, electronics and medical equipment are widely used. [0003] During the laser welding process, a bright and hot plasma will be formed above the molten pool. Current research believes that the plasma will shield the incident laser through absorption, refraction and scattering, and the periodic oscillation of the plasma will seriously affect the stability of the welding process. . A clear understanding of the char...
