Quizplus · Accepted Answer

The principal purpose of flux in welding operations is to prevent oxidation. Flux is a substance that is used to clean the surface of the metal being welded and prevent oxygen from contaminating the weld, which could lead to poor quality or weak joints. Slag is a byproduct of the welding process and is usually removed after the welding is complete. Enhancing flow or purifying the air are not primary purposes of the flux.
