The effect of flux chemistry on element transfer in submerged arc welding : application of thermochemical modelling

Coetsee, Theresa; Mostert, Roelf Johannes; Pistorius, Pieter Georg Hendrik; Pistorius, Petrus Christiaan (Elsevier, 2021-03)

Post-weld slag and weld metal analyses were used to interpret the effects of different commercial flux compositions on element transfer between molten flux (slag) and weld metal in Submerged Arc Welding (SAW). Selected ...
In situ modification of CaF2-SiO2-Al2 O3-MgO flux applied in the aluminium-assisted transfer of titanium in the submerged arc welding of carbon steel : process mineralogy and thermochemical analysis

Coetsee, Theresa; De Bruin, Frederik (MDPI, 2022-05-11)

Flux formulations are specified to target chemical and physico-chemical parameters. Chemical parameters set flux element transfer behaviours and weld metal oxygen contents. Physicochemical parameters such as slag viscosity, ...
Nano-strand formation in CaF2-SiO2-Al2O3-MgO flux reacted at 1350 °C with Al-Ti-Fe powder : SEM analyses and gas reaction thermochemistry

Coetsee, Theresa; De Bruin, Frederik (Elsevier, 2024-03)

Nano-strands form in fluoride-based slag during submerged arc welding (SAW) due to the re-condensation of gas species formed at high temperatures in the arc cavity. The SAW process is complex due to gas-slag-metal reactions ...
