The invention discloses a partition induction regulation and control device and method for high-strength steel laser cladding. The partition induction regulation and control device comprises a welding mechanical arm, a laser head, a shielding gas assembly, a magnetic induction coil, an infrared thermometer and a control system. The laser head is clamped at the tail end of the welding mechanical arm; the nozzle is connected with the laser head; the plurality of groups of magnetic induction coils are relatively independent, are arranged on the laser head through a coil bracket, and are used for performing zoned temperature control on a cladding area; the infrared thermometer is arranged on the coil bracket and is used for measuring the temperature of a cladding area; the laser head, the welding mechanical arm, the shielding gas assembly, the magnetic induction coil and the infrared thermometer are all connected with the control system. According to the zoning induction regulation and control device, zoning temperature control is conducted on a cladding area, precise regulation of local temperature is achieved, infrared temperature measurement real-time feedback and closed-loop control are combined, the uniformity and metallurgical bonding strength of a cladding layer can be remarkably improved, and cracks and defects are reduced.
