The cladding system disclosed by the embodiment of the invention comprises an in-light coaxial ball-feeding laser cladding head and a laser generator connected with the in-light coaxial ball-feeding laser cladding head. The laser emitted by the laser generator enters the in-beam coaxial ball-feeding laser cladding head to form cladding light beams to clad the clad material on the base material.

Indeed, in other embodiments, a storage device for storing the cladding material may be disposed at one side of the in-beam coaxial ball feeding laser cladding head, and a conveying channel for conveying the cladding material from the storage device to the nozzle 121 may be disposed.
The number of the cladding beams 14 is at least three, the at least three cladding beams 14 are annularly arranged and are intersected at one point to form a cladding point 141, and the cladding point 141 is used for cladding the solder ball 11, so that the solder ball 11 is melted into cladding liquid.
