A treatment process of liquid aluminum without the formation of hydrogen porosity needs to be explained. Concept Introduction: Degassing is a process of removing hydrogen from molten metal. It is necessary to remove hydrogen content from molten metals before casting to improve the quality of the casting. Degassing is performed in two ways: Diffusion of hydrogen into an inert gas bubble. The concentration of hydrogen into an inert gas bubble. Porosity is the major defect in a casting leads to the failure of casting.
