Abstract

Tungsten electrode contamination caused by metal vapour from a base metal during a tungsten inert gas welding was investigated. The metal ions transported from the weld pool surface were deposited on the tungsten electrode surface during welding. The tungsten fraction of the electrode surface layer was decreased because the deposited metal vapour diffused inside the tungsten electrode. The melting point of the electrode surface layer was lowered, decreasing to the electrode operating temperature. Results show that the electrode melted and deformed. This electrode contamination was promoted when a larger amount of metal ions was transported to the electrode surface.
