Abstract Recently, the processes involving simultaneous application of ultrasonic vibrations during conventional materials processing are attracting significant interests for improving process efficiency and material quality. It has been previously shown that the simultaneous application of ultrasonic vibrations (frequency of 20 kHz and vibration displacement of 23 μm) during continuous wave (CW) CO 2 laser surface melting results in melt expulsion and formation of surface holes.
