Zusammenfassung:The invention relates to the technical field of laser cladding, in particular to a global laser cladding system for the inner wall of a 12 m long oil casing. A laser head; the powder feeding system is used for conveying spherical nickel-based alloy powder with the melting point in the temperature range of 1300-1400 DEG C and the granularity in the range of 53-150 microns to the laser head and cladding the spherical nickel-based alloy powder on the inner wall of the pipe fitting through laser cladding; the workpiece rotating system is used for controlling the rotating speed of the pipe fitting to be cladded to be 25-55 degrees per second, and the rotating speed precision reaches 0.5 degree per second; the laser head walking system is used for controlling the laser head to move in the pipe fitting in the axial direction; the water cooling system is used for fully cooling the laser, the optical cable and the laser head; according to the system disclosed by the invention, the subsystems are mutually matched, so t
