METHOD FOR MANAGING QUALITY OF LASER CLADDING PROCESSING, AND LASER CLADDING PROCESSING DEVICE

摘要

Provided are a method for managing the quality of laser cladding processing and a laser cladding processing device by which the quality of a cladding layer formed on a processing portion of a workpiece can be managed by a simple configuration and reliably while suppressing manufacturing cost. The quality of the cladding layer is managed based on the intensity of infrared light S generated when metal powder P discharged toward laser beam R is melted in the air by the laser beam R.

主权项

1. A method for managing the quality of laser cladding processing where a cladding layer is formed on a processing portion of a workpiece by melting metal powder which is discharged toward laser beam irradiating the processing portion of the workpiece and which is supplied to the processing portion of the workpiece,
the method comprising managing the quality of the cladding layer based on an intensity of infrared light generated from the metal powder when the metal powder being discharged toward the laser beam is melted in the air by the laser beam.
