In-situ crack and keyhole pore detection in laser directed energy deposition through acoustic signal and deep learning

Lequn Chen, Xiling Yao, Chaolin Tan +6

Cracks and keyhole pores are detrimental defects in alloys produced by laser directed energy deposition (LDED). Laser-material interaction sound may hold information about underlyi…
