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

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.

Fatigue Behavior of Butt Welds with Slag Inclusions

Journal of Structural Engineering, 1984
The results of an experimental study on the fatigue behavior of transverse welded steel butt joints containing slag inclusion discontinuities are presented. Twenty‐four constant amplitude zero‐to‐tension fatigue tests were conducted. The 5 in. (127 mm) wide by 1 in.

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.

Some Feasibility Studies for Recycling of Steel Slag as a Useful Flux for Submerged Arc Welding

Journal of Advanced Manufacturing Systems, 2020
Protection of environment from industrialization and urbanization waste is the prime duty of engineers and researchers. Elimination of industrial waste completely is not possible because it is generally a byproduct of the process.

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.

Reusability of metallurgical slag waste in submerged arc welding powder for hardfacing

, 2020
Slag waste generated during the metallurgical process in a ferrochromium plant in Elazig, Turkey, ferro alloys and other required ceramic based powders were mixed to obtain recycled powders produced by submerged arc welding using the agglomeration method.
