摘要： A welding system that, using a junction at which a standing plate and a bottom plate meet as a welding line, makes an electrode weave centered on the welding line and thereby welds along the welding line. While weaving, the electrode moves forward in a welding advancement direction until a bottom-plate-side weaving edge. When the electrode arrives at the bottom-plate-side weaving edge, the electrode moves backward with respect to the welding advancement direction until a standing-plate-side weaving edge. The electrode repeats this weaving motion on the bottom-plate side and on the standing-plate side. The system can suppress occurrence of inferior bead appearance and of welding defects in horizontal fillet welding.

摘要： A welding system that, using a junction at which a standing plate and a bottom plate meet as a welding line, makes an electrode weave centered on the welding line and thereby welds along the welding line. In this welding system, control is performed such that the arc voltage at a standing-plate-side weaving edge is equal to or less than the arc voltage at a welding-line center position, such that the arc voltage at a bottom-plate-side weaving edge becomes equal to or greater than the arc voltage at the welding-line center position, and such that the arc voltage at the standing-plate-side weaving edge becomes lower than the arc voltage at the bottom-plate-side weaving edge. The system can suppress occurrence of inferior bead appearance and of welding defects in horizontal fillet welding.
