Flux and filler metals together are known as welding consumables. Stick electrode, flux-cored wires, solid wires, SAW wires and fluxes are some of the welding consumables employed during the welding process. However, flux does not form part of the final weld and so is ‘wasted’ during the course of welding

WELDING CONSUMABLES. In Welding, substances called filler materials or consumables are used. As the name implies, these substances provide a filler or a body of molten materials that provides a strong bond to be formed between the base metals used.
