The present invention discloses a
laser induced composite cladding measure and device for the automatic
powder feeder. The present invention couples the
laser beam and the
high frequency electromagnetic induction heating so as to realize the composite cladding between the
laser and the
induction heating. The device comprises a laser, a
laser light guide device, a laser gathering
system, a
high frequency induction heater, a
digital control machine tool and a workpiece holding device. In work, the distance between the surface of workpiece under treatment and the
induction heating coil is 1 to 10 mm. The present invention has a strong commonality and can conduct surface treatment of laser induced composite cladding high performance material coat toward the surface of the
solid components in various materials and the inner and outer surfaces of the tubular spare parts. The cladding measure is characterized in that: the
high frequency induction heater heats up the workpieces simultaneously and the automatic power feeder is applied to deliver the cladding
powder to the laser
irradiation area on the surface of the workpiece, so the
alloy powder is instantaneously melted under the action of laser beam to form an
alloy layer; and the maximum cladding speed reaches 10 m / min and the cladding efficiency is improved by one to ten times than the regular laser cladding and the powder
utilization rate exceeds 90 percent; the applicable cladding materials have a wide range, comprising various
wear resistant,
corrosion resistant materials or high temperature resistant oxidizing materials as well as the composite materials; moreover, the cladding layer has no pores and
crackles.
