WHAT IS SLAG IN WELDING Slag is a by-product of consumable electrodes containing flux. When these electrodes are used in welding they create a shielding gas cloud which does the job of protecting the weld pool and the arcLater when the weld has some time to cool it forms a layer of slag. This flux is also responsible for providing the deoxidizers and alloying elements for the welded area.
