Numerical simulation of welding temperature field, residual stress and deformation induced by electro slag welding

Computational Materials Science, 2012
Abstract To increase productivity, welding process with large heat input such as electro slag welding (ESW) process has been used to connect the joints between the diaphragm and the column plate in high-rise steel building. However, the heat input of ESW is much higher than those of the other welding processes, and the high heat input not only ...

Slag-metal reactions during welding: Part II. Theory

Metallurgical Transactions B, 1991
A kinetic model is developed to describe the transfer of alloying elements between the slag and the metal during flux-shielded welding. The model accounts for changes in alloy recovery based on the geometry of the resulting weld bead. It also distinguishes compositional differences between single-pass and multiple-pass weld beads.

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 ...

Slag-metal equilibrium during submerged arc welding

Metallurgical Transactions B, 1981
A thermodynamic model of the equilibria existing between the slag and the weld metal during submerged arc welding is presented. As formulated, the model applies only to fused neutral fluxes containing less than 20 pct CaF2, however some results indicate that the model may be useful in more general cases as well.

Influence of welding conditions and flux composition on chemistry of welds using recycled steel slag in submerged arc welding

Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, 2023
The slag generated by steel-making plant has been employed to manufacture flux essential for submerged arc welding process. The developed flux has been used for depositing beads on plates, and the weld metal chemistry has been evaluated. The effect of welding conditions and flux composition on element transfer behavior has been investigated.

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 ...

Influence of weld slag aggregate in high-performance concrete

Proceedings of the Institution of Civil Engineers - Waste and Resource Management, 2016
Rapid increase in urban infrastructural developments in developing countries such as India leads to the need for natural resources such as river sand. The accessibility of the natural resources is diminishing rapidly. At present, other sources of fine aggregates are in great demand.
