Welding flux

Cleaning, the removal of unwanted matter, is the beginning of the treatment cycle for metal. The unwanted matter may be carbon smut, welding flux, ink, oxidation products, oil, fingerprints, or other material. Cleaners may be classified as solvent-based or aqueous. Within the aqueous class there are many subclasses, the most important of which are the alkaline cleaners. There are also a variety of ways to apply cleaners. As of the mid-1990s, solvent-based cleaner usage is declining.

Welds on steelwork need special attention because of the different composition of weld metal and adjacent steelwork, the rough surface and spatter caused by welding and the presence of welding flux. The latter is often alkaline and destructive to many paints. It is necessary to clean thoroughly, preferably by reblasting for 25-50 mm each side of the weld, fare the rough metal and wash off residual flux. The cleaned surface should then be stripe coated with the primer used on the remainder of the surface. 

Rusty pipe should not be used. The rust and loosened mill scale will travel around the circuit to block the suction strainer and the drier. Other avoidable debris are loose pieces of weld, flux, and the short stubs of welding rod often used as temporary spacers for butt welds. Pipe should only be cut with a gas torch if all the oxidized metal can be cleaned out again before closing the pipe. 

Used industrially as a cleaning agent, disinfecting agent, insecticide, to etch glass, and as a welding flux. 

Used industrially as welding flux, wood preservative, and in the ceramic industry. 

Used industrially for etching glass, as an antiseptic and disinfectant, as a leather bleach, in the production of tin plate, for rust removal, as a welding flux, as a neutralizer in laundry rinsing operations, and as a cleaner for stone and brick building faces. Used to preserve zoological and anatomical specimens. 

Lead bromide is used for developing images in photography as inorganic filler in fire-retardant plastics as a photopolymerization catalyst for acrylamide monomer and as a welding flux for welding aluminum or its alloys to other metals. 

Trimethylborate is a colourless transparent liquid which boils at 68.7°C. It is used as gaseous welding flux and as a parent component for some boron derivatives, such as sodium and potassium boranes, trimethoxy-boroxol, etc. E.g., trimethoxyboroxol can be rather easily formed when trimethylborate interacts with boron anhydride.
