Relationship Between Metal Vapor in Arc and Droplet Transfer Mode in GMAW

open access: yesTaiyuan Ligong Daxue xuebao, 2022
The relationship between metal vapor in arc and droplet transfer mode in GMAW was reviewed. The results show that when welding with high current and corresponding welding parameters and different shielding gases, the conductivity of the vapor in arc ...

Transfer of metals in the liquids of electronic cigarettes

open access: yesInhalation Toxicology, 2020
Objectives: E-cigarettes are electronic devices containing a liquid that usually consists of a mixture of glycerol, propylene glycol and nicotine, with or without flavorings, in various concentrations. A vapor or aerosol is produced, and inhaled from the user, when this liquid is heated by a heating coil.

Coulomb Drag and Heat Transfer in Strange Metals

open access: yesPhysical Review Letters, 2023
We address Coulomb drag and near-field heat transfer in a double-layer system of incoherent metals. Each layer is modeled by an array of tunnel-coupled SYK dots with random inter-layer interactions. Depending on the strength of intra-dot interactions and inter-dot tunneling, this model captures the crossover from the Fermi liquid to a strange metal ...

Charge transfer transitions in glasses - Attempt of a systematic review

open access: yesOptical Materials: X, 2021
In glasses, even low levels of dopants or impurities can give rise to very intense and broad charge transfer transitions from ligands (e.g. oxygen or fluorine ions) to the metal ion (L→M), absorbing strongly in the short wavelength ultraviolet.

Acoustic signal analysis for classification of transfer mode in GMAW by noncontact sensing technique [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2006
The objective in this paper is to investigate acoustic signal emitted during metal transfer in gas metal arc welding process (GMAW). Short circuit, globular transfer and spray transfer were classified by using dynamic microphone.
