Abstract
PURPOSE: To stabilize weld heat input and a weld bead height by controlling the projecting length of a welding wire and the speed of a traveling carriage or the feed speed of the wire according to the state of the arc in automatic welding a narrow groove with plural electrodes in gas-shielded arc welding.
CONSTITUTION: In welding the base metals to be welded automatically with at least two electrodes and a welding torch by narrow groove gas-shielded arc welding, the controlling of the projecting length of a wire and the controlling of the traveling speed of a traveling carriage are carried out alternatel and time-dividedly in welding with at least one electrode, and the controlling of the projecting length of the wire and the controlling of the feed speed of the wire are carried out alternately and time-dividedly in welding with at least another electrode. The heat input controlling by the wire projection controlling and the bead height controlling by the traveling speed controlling and the wire feed speed controlling exhibit effect without preceding of only the wire projection length controlling, whereby the weld heat input is stabilized and the welding of constant height is carried out.
