The invention provides a double-metal wire material laser cladding system and method. The double-metal wire material laser cladding system comprises a laser (4), a first metal wire (5), a second metalwire (6), a conductive nozzle (7), a first wire feeder (8), a second wire feeder (9) and a wire material heating device (10); the first metal wire (5) and the second metal wire (6) penetrate throughthe conductive nozzle (7) side by side and point to the to-be-clad surface of a workpiece (1); and the conductive nozzle (7) and the workpiece (1) are respectively connected to two electrodes of the wire material heating device (10). According to the double-metal wire material laser cladding system and method, a double-metal wire laser cladding scheme is innovatively arranged, the double-metal wire material laser cladding method is initially realized on the basis of a traditional single-metal wire material laser cladding technology, and the problems that the cladding efficiency and the laser power can not be improved in the same proportion in application, raw material components of the laser cladding cannot be adjusted, and the laser energy utilization rate is low in the existing wire material laser cladding technology are solved.
