摘要： The present invention suppresses the occurrence of inferior bead appearance and of welding defects in horizontal fillet welding. A welding system that, using the 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.

摘要： The present invention suppresses the occurrence of inferior bead appearance and of welding defects in horizontal fillet welding. A welding system that, using the 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.

摘要： The purpose of the present invention is, in gas shielded arc welding using an active gas and flux-cored wire with primer-coated steel plates as a base material, to suppress occurrences of poor appearance in welded parts caused by pores originating in the primer. A welding method for a welded article positions a first steel plate and a second steel plate formed from primer-coated steel plates in a T shape and welds each of corner parts formed in two locations. Using flux-cored wire (100), which is formed by filling the inside of a steel outside skin with flux, and a shielding gas (carbon dioxide gas), a welding pool (400) is formed in the corner part by supplying a welding current to the corner part via an arc from the flux-cored wire (100) by means of the shielding gas; additionally, an alternating magnetic field is applied to the welding pool, and the welding current and the alternating magnetic field are set such that the welding current (A) and the magnetic flux density (mT) for the alternating magnetic field have a relationship of 20000 ≤ welding current × magnetic flux density ≤ 30000.
