Modelling of Slag Produced in Submerged Arc Welding

2020
This study has been conducted to reveal the effects of flux composition on slag produced and wire consumption. RSM was used for designing the experiments. Mathematical modeling was done for the output in terms of flux composition. The study reveals that the slag produced is dependent upon the basicity index of the flux and CaF2 used as a flux ...

Experimental investigations and optimization of weld bead characteristics during submerged arc welding using recycled steel slag as a flux

Proceedings of the Institution of mechanical engineers. Part E, journal of process mechanical engineering, 2023
A novel methodology has been established which allows to recycle steel slag as a suitable flux for submerged arc welding. The flux produced using waste slag as a raw material has been applied to deposit beads on plates.

Application of Mixture design in optimization of physical properties of slag during self-shielded flux-cored wire arc welding process

2023 IEEE 5th International Conference on Modern Electrical and Energy System (MEES), 2023
The analysis of recent publications showed the importance of optimising the slag system during the flux-cored arc welding. It was determined that it is rational to use two parameters to optimize the slag composition: viscosity and surface tension.

Petrographic Study of Welding Slags

Russian Metallurgy (Metally), 2020
The results of petrographic studies of the welding slags of electrodes UONI-13/55, Philips 27P, OZS-4, and VSTs-4 are presented. These electrodes are found to form welding slags having various phase compositions and morphologies. The phase compositions of the slags are shown to affect the physical properties of their melts, in particular, viscosity ...

Microstructure of the Acid Welding Slag

Applied Mechanics and Materials, 2012
Several E4303 type welding electrodes with different coating compositions were designed and manufactured using TL-25 welding electrode extrusion press. Welding slags of these electrodes were collected after welding on the low carbon steel, then the microstructure and the phase constitutes of the slags were investigated by optical microscope,scan ...

Consequences of the reaction between metal and slag during melting welding

Welding International, 2021
The reactions of interaction between metal and slag in fusion welding are considered. For the first time the equivalent impurities is proposed. Equivalent allows multiple correlation to be reduced to correlation of two variables in order to determine the
