Paper Abstract

The first on-line detection of cracks generated ina laser cladding process is obtained by a very-sensitiveoptical interferometer. The instrument is based on a homodyneMichelson-type configuration and uses an He-Ne laser assource. The instrumental performances (10 MHz bandwidth, 1Angstrom resolution) are maintained during the in-fieldtrials and confirm the feasibility of using opticalinterferometry in material processing diagnostic.
