Which of the following most accurately describes the problem?

AN improved electrode for use in the • argon-are welding process, is announced by Murex Welding Processes, Ltd., Waltham Cross, Herts. Whilst an electrode used in argon-arc welding is theoretically non-consumable, wastage occurs in practice, in con • sequence of the need for regrinding to keep the tip of the electrode free from contamination.

With a zirconiated tungsten electrode, as now developed, it is possible to carry on welding after contamination. The tip of the electrode does not become " wetted" and hence no globule forms on it. as in the case of pure tungsten or thoriated tungsten rods.
