Abstract
A narrow groove arc welding process includes angular oscillation of a non-consumable electrode having a tip which is radially displaced with respect to the central axis of the electrode. This provides for improved arc sweep and can be combined with prior art lateral and pivotal electrode oscillation techniques. A non-consumable electrode for use in this process is provided with a radially displaced tip. The electrode can be easily replaced by detaching it from a permanent rod electrode.
