Abstract
An arc welding process using a consumable stranded wire electrode which is formed either by integrally intertwisting a plurality of wire elements substantially of the same sectional area such that the lines connecting center points of adjacent wire elements do not form a regular polygon in a sectional plane or by integrally intertwisting a plurality of wire elements of different sectional areas such that the lines connecting center points of wire elements of larger diameter do not form a regular polygon in a sectional plane wherein the consumable electrode is imparted with a bending trait and contacted with a surface on the inner periphery and at the outlet end of a conducting tip, and the arc is directed toward a center weld line to thereby obtain a stable arc.
