Welding rod grade bauxite requires a very low Fe2O3 content, compared to refractory grade. Welding fluxes are a small but valuable market for calcined bauxite. Here, calcined bauxite is used in submerged arc welding to shield the molten weld pool from the atmosphere during the weld’s application or pacement. Calcined bauxite may make up to 25% of the welding flux. For welding fluxes, it is critical that residual moisture content of the bauxite should not exceed 0.5%. Any moisture present in the flux can potentially reduce to hydrogen when exposed to the welding arc which can cause brittleness. Strict limits are also imposed on the sulphur and phosphorus content of the bauxite because presence of these can cause cracking.
