Numerical Analysis of Heat Transfer and Fluid Flow in Keyhole Plasma Arc Welding
Numerical Heat Transfer, Part A: Applications, 2011Modeling and simulation of fluid flow and heat transfer in keyhole plasma arc welding is of great significance for optimizing the process parameters, and obtaining deep insight of the process mechanisms. In this study, a three-dimensional transient model is established to analyze numerically the evolution of the weld pool, the keyhole shape and ...

In-situ synthesis of titanium carbides in iron alloys using plasma transferred arc welding
Surface and Coatings Technology, 2013Abstract The synthesis of Fe–TiC metal matrix composite during metal deposition with laser and arc welding techniques is of technical and economic interest for hard surfacing of engineering components. Recent studies linked the resistance to abrasive wear with the size and morphology of TiC precipitates, which are strongly dependent on the deposition

Homogeneity of metal matrix composites deposited by plasma transferred arc welding
2010Tungsten carbide-based metal matrix composite coatings are deposited by PTAW (Plasma Transferred Arc Welding) on production critical components in oil sands mining. Homogeneous distribution of the reinforcement particles is desirable for optimal wear resistance in order to reduce unplanned maintenance shutdowns.

Welding in the World, 2018
The residual stress produced in plasma transferred arc welding (PTAW) has strong effects on the service performance of remanufacturing components. In this study, a novel non-destructive testing method based on spontaneous magnetic signals is used to characterize the residual stress in PTAW. Experimental results show that both magnetic signal tangential

Welding in the World, 2019
The heat-transfer properties of variable polarity plasma arc (VPPA) during the electrode negative (EN) phase and electrode positive (EP) phase in the real-time process are the key factors for the stability control and optimization of the welding process.

Imact of parameters of plasma transferred arc welding process on the weld layer geometry
2014In many cases parts of machines and structures are exposed to wear or action of aggressive corrosive environments. In such cases, the structure integrity can be compromised in a relatively short period of time. Therefore, to extend the service life of machine elements the common practice is to protect their surfaces by coating.
