Abstract:
A laser processing head in accordance with the present invention comprises: a laser emitting unit for irradiating a workpiece with a laser light; and a powder feeder disposed around a periphery of the laser emitting unit for discharging filler material powder to the workpiece, in which the powder feeder includes: a position adjustment mechanism for adjusting a position where the powder concentrates; and a powder concentration diameter adjustment mechanism for adjusting a diameter of the filler material powder. The laser processing head further comprises a controller for controlling the position adjustment mechanism and the powder concentration diameter adjustment mechanism.
