Abstract

The invention discloses a laser welding device for girth welding of large length-to-diameter ratio fuel rod cladding. The laser welding device comprises a laser welding head, a servo motor, a driving three-jaw chuck, a gas protective jacket, a driven three-jaw chuck and a plurality of bearing rollers, wherein the gas protective jacket comprises a protective jacket upper half part, a protective jacket lower half part, protective gas input pipelines, a protective lens support and a protective lens; the servo motor, the driving three-jaw chuck, the gas protective jacket, the driven three-jaw chuck and the bearing rollers are sequentially distributed from left to right. With the adoption of the device, welding of rotary workpieces which are made of different materials and have different diameters and different lengths can be realized, and the welding precision and the efficiency are high.

Description

technical field [0001] The invention belongs to the technical field of laser welding and the field of nuclear fuel assembly processing, and relates to a laser welding device for cladding welding of fuel rods with a large length-to-diameter ratio. Background technique [0002] Laser welding is a high-energy beam welding method, which has the advantages of high energy density, small welding heat input, small and beautiful weld seam, narrow welding heat-affected zone, high welding efficiency, clean and environmental protection, etc., and is widely used in various welding fields. [0003] Large aspect ratio workpieces, such as slender rods, tubes, stepped shafts, etc., are prone to welding deformation during welding and affect the coaxiality of the rotor, so it is necessary to control the welding heat input; traditional welding methods such as friction welding, TIG welding, etc. , either the welded joint has large deformation, which is not suitable for welding thin-walled pipe f...
