TL;DR: In this paper, a BAM of low carbon steel and austenitic-stainless steel was fabricated using a gas-metal-arc-welding (GMAW)-based additive manufacturing (WAAM) process.

TL;DR: In this article, the authors fabricate a BAMS by sequentially depositing the austenitic stainless-steel and Inconel625 using a gas-metal-arc-welding (GMAW)-based wire-and-arc additive manufacturing (WAAM) system.

TL;DR: In this article, the AISI H13 tool steel, a popular die-casting tool metal, is manufactured by cold metal transfer (CMT)-based additive manufacturing (WAAM) and is then comprehensively analyzed for its microstructural and mechanical properties.

TL;DR: In this article, the authors investigated the mechanical properties of the wire + arc additively manufactured Inconel 625 thin wall and found that the annealing procedure improved the ultimate tensile strength by 5%.

TL;DR: In this article , a real-time anomaly detection method that uses a convolutional neural network (CNN) in wire arc additive manufacturing (WAAM) is presented, which enables creation of CNN-based models that detect abnormalities by learning from the melt pool image data, which are pre-processed to increase learning performance.
