Gas Mixtures for Welding with Micro-Jet Cooling

open access: yesArchives of Metallurgy and Materials, 2015
Welding with micro-jet cooling after was tested only for MIG and MAG processes. For micro-jet gases was tested only argon, helium and nitrogen. A paper presents a piece of information about gas mixtures for micro-jet cooling after in welding.

Creating wounds in cell monolayers using micro-jets [PDF]

open access: yesBiomicrofluidics, 2021
Abstract Many wound-healing assays are used in cell biology and biomedicine; they are often labor intensive and/or require specialized and costly equipment. We describe a contactless method to create wounds with any imaginable 2D pattern in cell monolayers using micro-jets of either media or an immiscible and biocompatible fluorocarbon (

Visualization of cavitating micro jets [PDF]

open access: yesEPJ Web of Conferences, 2012
The paper deals with one experimental set up integrated for research of the cavitating micro flows, which is incipient behind the micro channel or micro discharge nozzle outlet port. Experimental system is integrated from three major systems: hydraulic circuit with installed discharge nozzle (or micro channel), subsystem for data acquisition and data ...

Numerical study on the desorption processes of oil droplets inside oil-contaminated sand under cavitation micro-jets

open access: yesUltrasonics Sonochemistry, 2021
The removal of the adsorbed oil droplet is critical to deoiling treatment of oil-bearing solid waste. Ultrasonic cavitation is regarded as an extremely useful method to assist the oil droplets desorption in the deoiling treatment.

Development and Application of Constant Flow Generating Injector with Pulse Energy Source as Driving Force [PDF]

open access: yes한국정밀공학회지, 2019
A pulsed-power source has the advantage of releasing a peak power over a short time interval. In this study, we implemented two types of such energy source, namely laser and dielectric break down power sources.

MAG Welding Process with Micro-Jet Cooling as the Effective Method for Manufacturing Joints for S700MC Steel

open access: yesMetals, 2021
Advanced high-strength steel (AHSS) steels are relatively not very well weldable because of the dominant martensitic structure with coarse ferrite and bainite.
