Detection of Internal Holes in Additive Manufactured Ti-6Al-4V Part Using Laser Ultrasonic Testing
Jie Yu,Dongqi Zhang,Hui Li,Changhui Song,Xin Zhou,Shengnan Shen,Guoqing Zhang,Yongqiang Yang,Hongze Wang +8 more
TL;DR: In this paper, a Q-switched pulsed laser was used to generate ultrasound waves on the top surface of a Ti-6Al-4V alloy part, and a laser Doppler vibrometer (LDV) was utilized to detect the ultrasound waves.
In-situ capture of melt pool signature in selective laser melting using U-Net-based convolutional neural network
Qihang Fang,Zhenbiao Tan,Hui Li,Shengnan Shen,Sheng Liu,Changhui Song,Xin Zhou,Yongqiang Yang,Shifeng Wen +8 more
TL;DR: A novel method to capture melt pool signature using a U-Net-based convolutional neural network is described, which successfully eliminated the interferences, and reached the highest MIoU at a relatively low computational cost of 37 ms on average.

In-Situ Laser Polishing Additive Manufactured AlSi10Mg: Effect of Laser Polishing Strategy on Surface Morphology, Roughness and Microhardness.
TL;DR: In this article, a numerical transient model was used to reveal the rough surface evolution mechanism during laser polishing, and the experimental results showed that after laser-polishing, the surface roughness of Ra and Sa of the upper surface can be reduced from 12.5 μm to 3.7 μm and from to 29.3 μm, respectively, due to sufficient wetting in the molten pool.
