Welding of molybdenum
Welding molybdenum is a complex process because of its instability to crystallization
Recommended welding molybdenum parts with prior, concomitant and subsequent heating up to 300−650°C. Vacuum annealing t° 1800 °C for 1 hour increases the ductility of the welded seams.
Welding was performed with a continuous flow of inert gas to the burner. The flow of inert gas cools the weld, and the removal of hazardous from the welding area that provides clean impurities the introduction of sutures. When welding plates with thickness up to 1.5 mm in the burner serves a mixture of 50% AG + 50%, when welding thicker material — only helium.
