TL;DR: In this paper, a three-dimensional numerical model was developed to investigate the fluid flow and heat transfer behaviors in multilayer deposition of plasma arc welding (PAW) based wire and arc additive manufacture (WAAM).

TL;DR: In this article, a maraging steel wall structure was built layer-by-layer to study oxide accumulation mechanisms and the influence of oxides on the subsequent deposition, and an online arc welding camera was also applied to investigate the wetting and spreading behaviour of the deposition on different surface conditions.

TL;DR: A novel low-cost optical-sensor-based monitoring system working under passive mode to monitor the wire + arc additive manufacture process, particularly for plasma arc welding, is introduced.

TL;DR: In this article, the use of cold metal transfer-based additive manufacturing (WAAM) process for the production of maraging steel bulk material is reported, and the effect of building strategies including oscillation, parallel and weaving on bead shape is investigated.

TL;DR: In this article, an innovative welding method referred to as adjacent welding was addressed, which greatly improved the tensile strength of a Ti/Cu dissimilar joint, and the strength of new joint could reach up to 89% that of copper base metal.
