Measuring the Depth of Subsurface Defects in Additive Manufacturing Components by Laser-Generated Ultrasound
A new method to measure the depth of subsurface defects in additive manufacturing components is proposed based on the velocity dispersion analysis of Lamb waves by the wavelet-transform of laser ultrasound. Firstly, the mode-conversion from laser-generated surface waves to Lamb waves caused by subsu...
