Main Alloy Elements in Covered Electrodes in Terms of the Amount of Oxygen in Weld Metal Deposits (wmd)
There were investigated properties of WMD, especially metallographic structure, toughness and fatigue strength of welds with various oxygen amount. The connection between the properties of welds with the content of oxygen in WMD were carried out. The research results indicate that it should be limited oxygen content in steel welds. Subsequent researchers could fi nd more precisely the most bene...
متن کاملStructure of water layers on hydrogen-covered Pt electrodes
The structure of water layers above hydrogen-covered Pt(111) surfaces at room temperature has been studied by ab initio molecular dynamics simulations based on periodic density functional theory calculations. Fully hydrogen-covered Pt(111) with additionally either a hydrogen vacancy or another hydrogen adatom have been considered. The resulting structures have been analyzed in detail as a funct...
متن کاملImpermeable flexible liquid barrier film for encapsulation of DSSC metal electrodes
Encapsulation of electronic devices such as dye-sensitized solar cells (DSSCs) is prone to degradation under normal atmospheric conditions, even with hermetic barriers on the metal electrodes. Overcoming this problem is crucial to increasing DSSC lifetimes and making them commercially viable. Herein, we report a new impermeable flexible liquid barrier film using polyvinyl alcohol (PVA) and part...
متن کاملEvaluation of metal weld-zone by using Poisson’s ratio distribution
Poisson’s ratio has not received much attention because of its narrow range of measured values and difficulties in measurement. In previous work, genuine non-destructive evaluation method of characterizing weld-zone using Poisson’s ratio distribution was proposed. The method was to use immersion ultrasonic testing for measuring longitudinal and transverse wave speeds simultaneously. In present ...
متن کاملMinimising Hic/hac in Steel Using Low Hydrogen Electrode for Smaw
An improved welding electrode for producing weld metal having low amount of hydrogen therein so that hydrogen assisted cracking in weld zone is minimised. This is especially beneficial for welding high strength steel having tensile strengths of about 70000 psi or above. The reduction of slag /metal reaction temperature during welding have been found to have additional advantage of reducing the ...
