Resumen:
Real time detection of pulsed laser surface melting was performed by analyzing the photoacoustic signals produced on the samples, Comparison between the amplitudes of the transversal and longitudinal waves allowed us to identify the fluence thresholds for surface melting. The method was tested with AISI 304 stainless steel samples and the results obtained were checked against direct metallographic analysis. (C) 1997 American Institute of Physics.
