For manual arc welding electrodes with a thick layer covering the chemical reactions between metal arc gases and slag flow at 2100-2300 C in a time of transition drops of molten metal through the electrode and cover arc gap. Further physical and chemical processes occur in the weld pool. The main chemical reaction during welding under flux occur only under a layer of molten flux in the welding bath. Consider key reaction in the weld zone of steel, as the most popular metal that is to be welded. Oxidation. In … Read More…
