“…Arc welding, plasma cutting and plasma spraying were discussed in the 2017 Plasma Roadmap as three of the most important applications. Significant advances in the science relating to modeling of various aspects of these applications were made in the past 5 years, largely addressing the challenges identified [207]. In recent years, some thermal plasma applications play more and more important roles in the low-carbon and green growth development worldwide as was also mentioned in the 2017 Plasma Roadmap.…”

The 2022 Roadmap is the next update in the series of Plasma Roadmaps published by Journal of Physics D with the intent to identify important outstanding challenges in the field of low-temperature plasma (LTP) physics and technology. The format of the Roadmap is the same as the previous Roadmaps representing the visions of 41 leading experts representing 21 countries and five continents in the various sub-fields of LTP science and technology. In recognition of the evolution in the field, several new topics have been introduced or given more prominence. These new topics and emphasis highlight increased interests in plasma-enabled additive manufacturing, soft materials, electrification of chemical conversions, plasma propulsion, extreme plasma regimes, plasmas in hypersonics, data-driven plasma science and technology and the contribution of LTP to combat COVID-19. In the last few decades, LTP science and technology has made a tremendously positive impact on our society. It is our hope that this roadmap will help continue this excellent track record over the next 5–10 years.

Cold metal transfer (CMT) is a variant of gas metal arc welding (GMAW) in which the molten metal of the wire is transferred to the weld pool mainly in the short‐circuit phase. A special feature here is that the wire is retracted during this strongly controlled welding process. This allows precise and spatter‐free formation of the weld seams with lower energy input. To simulate this process, a model based on the particle‐based smoothed particle hydrodynamics (SPH) method is developed. This method provides a native solution for the mass and heat transfer. A simplified surrogate model was implemented as an arc heat source for welding simulation. This welding simulation model based on smoothed particle hydrodynamics method was augmented with surface effects, the Joule heating of the wire, and the effect of the electromagnetic forces. The model of metal transfer in the cold metal transfer process shows good qualitative agreement with real experiments.

“…We have applied this incompressible SPH method to the thermofluid simulations of molten metal flows in several kinds of arc welding processes such as GTA weding, 133,134) GMA welding, [135][136][137][138][139] SA welding, 140,141) and Flux-Cored Arc (FCA) welding. 142) Because this incompressible SPH method offers high adaptability for other types of metal processing, it has also revealed the molten metal formation processes with convective and diffusive heat transports during dissimilar Resistance Spot (RS) welding 143,144) and Electroslag (ES) welding 145) collaborating with the experiments, 146,147) and dross formation during gas cutting.…”

This article reviews and discusses the recent progresses of studies with the concept of “Computational plasma fluid mechanics”. Computational demonstrations show that the inhouse simulation codes such as PLASTIPC (PLasma All-Speed Turbulence with Implicit Pressure Code) have captured hydrodynamic instabilities and reproduced flow dynamics in thermal plasma – nonionized gas coexisting systems. A unique method has made it feasible to study collective growth of binary alloy nanoparticles by numerical analysis. SPH (Smoothed Particle Hydrodynamics) method with incompressibility modification has achieved complex behaviors of molten metal involving phase change, flow, heat transport, material mixing, and large deformation during arc welding. It is essential to study thermal plasma processes as comprehensive fluid systems in which hot plasma, cold nonionized gas, and materials coexist. The viewpoint and approaches of fluid mechanics as well as plasma physics are indispensable. Computational study will play a more important role in giving us new and deeper insights.
