Intelligent control of laser welding and additive device and method

Abstract

This invention relates to the field of laser welding and additive manufacturing technology, and discloses an intelligent controlled wire and powder co-feeding laser welding and additive manufacturing device and method. The device includes a housing, a fiber laser transmission component, a powder feeding mechanism, a wire feeding mechanism, a detection mechanism, and a control mechanism. The powder feeding mechanism includes an annular support plate, a main powder feeding tube, multiple secondary powder feeding tubes, a first angle adjustment component, a second angle adjustment component, and an angle coordination connection component detachably connected between the first angle adjustment component and the multiple second angle adjustment components. The wire feeding mechanism includes a wire feeding gun and a third angle adjustment component connecting it to the housing. This invention obtains the welding angle through the detection mechanism, and the control mechanism adaptively adjusts the angles of the powder feeding tube and the wire feeding gun according to different welding angles, realizing adjustment in flat welding, fillet welding, and overhead welding scenarios. Under large angle deflection, it can be adjusted to the optimal angle matching the current welding direction, overcoming the problem of uneven powder feeding caused by gravity.
