Abstract
In the welding of aluminum, it is important to provide a stable gas shield to exclude not only oxygen, but any sources of hydrogen, from the arc environment. Common sources of hydrogen are humidity in the air around the arc, moisture in the shielding gas, and residual lubricants on the surface of the welding consumable. Since molten aluminum can absorb seventy times more hydrogen than solid aluminum, as the aluminum cools, it releases hydrogen that then becomes trapped in the form of hydrogen bubbles in the solidifying metal
Key Words: Hydrogen, Iionization tendency, activated gas
