The invention discloses an ultrahigh-speed
laser cladding
system and
laser cladding method. The ultrahigh-speed
laser cladding
system comprises a laser device for generating a laser beam, a
heating power source, a
powder feeder and
powder heating tube assemblies, wherein each
powder heating tube
assembly is composed of an outer
ceramic tube,
electromagnetic heating assemblies and an inner ceramictube, each inner
ceramic tube is arranged in the corresponding outer
ceramic tube, and the
electromagnetic heating assemblies are arranged in each inner ceramic tube; the
electromagnetic heating assemblies are arranged between each inner ceramic tube and the corresponding outer ceramic tube; the
heating power source is connected to the electromagnetic heating assemblies through wires; the powder feeder communicates with the inner ceramic tubes through powder feeding tubes, and after normal-temperature
metal powder in the powder feeder enters the inner ceramic tubes through the powder feeding tubes, the normal-temperature
metal powder is heated into high-temperature
metal powder by the electromagnetic heating assemblies in the inner ceramic tubes; and the extension line of the laser beam and the inner ceramic tubes intersect at a
molten pool on the surface of a workpiece to be cladded. According to the ultrahigh-speed laser cladding
system and laser cladding method, ultrahigh-speed laser cladding technology based on improvement of the initial temperature of the
metal powder is achieved on the basis of traditional powder laser cladding technology for the first time, and the problem that the cladding efficiency of the powder laser cladding technology is low is solved.
