Technical Advice on welding Magnesium

When welding Magnesium, the problem is the oxide that builds up on the surface. To obtain good results the surface should be cleaned mechanically with a stainless steel brush. For chemically cleaning of magnesium, a solution of 24 oz. Chromic acid, 5-1/3 oz. ferric nitrate and 1/16 oz. potassium fluoride in enough water to make one gallon. Bring the solution to 70-90° F then immerse the part for 3 minutes and rinse in hot water. Make sure that both the welding joint and the filler rod are properly cleaned. For the Tig welding of magnesium use a Zirconiated Tungsten, AC welding current, and pure Argon shielding gas to offer proper melt pool protection. A Argon / Helium shielding gas mixture may be used when increased temperature and cleaning action is preferred.
