Welding structure for laser indirect radiation heat conduction brazing of optical assembly and using method of welding structure

The invention belongs to the technical field of laser brazing, and discloses a welding structure for laser indirect radiation heat conduction brazing of an optical assembly and a using method of the welding structure, and the welding structure comprises an optical assembly mounting plate, the optical assembly, an optical element adjusting seat, a connecting screw and a heat conducting sheet. The heat-conducting fin is connected to the optical component mounting plate and corresponds to the mounting position of the optical component, the optical component mounting plate is partially cut along the edge of the heat-conducting fin, and a semicircular arc is reserved for connection to form a kerf. During use, the optical component is placed at a preset position of the optical component mounting plate, the connecting screws are screwed into the threaded holes in the periphery, the height and the angle of the optical component are adjusted by adjusting the screwing depth of the connecting screws into the threaded ho
