Shielding Gas - Wikipedia, The Free Encyclopedia
And the ease with which they undergo ionization. Gases heavier than air (e.g. argon) blanket the weld and require lower flow copper, and some exotic metals. Increased oxygen makes the shielding gas oxidize the electrode, which can lead to porosity in the deposit if the electrode does ... Read Article
