Abstract
The invention is a welding method capable of controlling an arc heat distribution on a groove face of a base metal, which comprises increasing or decreasing the melting rate of a welding wire relative to the feeding rate of the welding wire by changing the characteristic of an arc current to thereby change an arc generating position of a fusing end of the welding wire, wherein an AC arc welding operation is performed by changing the polarity of the welding wire as the characteristic of the arc current; and a welded joint structure formed by the welding method.
