TL;DR: In this paper, the current status of research on the structural design and preparation of complex pure copper parts by researchers using selective laser melting (SLM), selective electron beam melting (SEBM), and binder jetting (BJ) is reviewed.

TL;DR: In this paper, Li et al. employed laser cladding for the preparation of NiCrAlY/Ag2O/Ta2O5 on Inconel 625 alloy substrate.

TL;DR: In this article, the application of pulsed laser in alloy welding is described and the main welding problems and prevention methods are summarized, the index had been proposed to predict the sensitivity of solidification cracks, the formation and growth processes of hot cracks in pulsed Laser welding was more comprehensively analyzed.

TL;DR: This work developed an innovative welder intelligence-enhanced deep random forest fusion (WI-DRFF) approach, aiming to describe the dynamics of front-side molten pool and accurately predict the weld penetration and is a new paradigm in the digitization and intelligence of welding process.

TL;DR: An end-to-end visual-acoustic penetration recognition (VAPR) framework based on a hybrid convolutional neural network (CNN) and extreme learning machine (ELM) and employed the ELM model as a strong tool to classify penetration status.
