A Passive Imaging System for Geometry Measurement for the Plasma Arc Welding Process [PDF]
IEEE Transactions on Industrial Electronics, 2017 Automatic and flexible geometry measurement of the weld pool surface can help better understand the complex welding processes and even provide feedback to better control this process. Most of existing imaging systems use an additional source of illumination to remove the light interference coming from the welding arc but it is usually costly.

Advanced Engineering Materials, EarlyView.Laser remelting of a CrMnFeCoNi high‐entropy alloy reveals that optimal chemical homogenization occurs between 30 and 40 J·mm−2. Within this range, elemental segregation is reduced by over 30% compared to the as‐cast state. The study establishes this window as a fast, effective alternative to prolonged annealing for achieving uniform elemental ...

Influence of the nozzle head geometry on the energy flux of an atmospheric pressure plasma jet
EPJ Techniques and Instrumentation, 2021 The influence of different nozzle head geometries and, therefore, the variation of the excitation and relaxation volume on the energy flux from an atmospheric pressure plasma jet to a surface have been investigated.

Arc spaces, motivic measure and Lipschitz geometry of real algebraic sets [PDF]
Mathematische Annalen, 2019 We investigate connections between Lipschitz geometry of real algebraic varieties and properties of their arc spaces. For this purpose we develop motivic integration in the real algebraic set-up. We construct a motivic measure on the space of real analytic arcs.

Advanced Functional Materials, EarlyView.This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

Penetration Estimation of GMA Backing Welding Based on Weld Pool Geometry Parameters
Chinese Journal of Mechanical Engineering, 2019 Penetration estimation is a prerequisite of the automation of backing welding based on vision sensing technology. However, the arc interference in welding process leads to the difficulties of extracting the weld pool characteristic information, which ...
