摘要： A welding method is disclosed for butt welding a first base material 1 and a second base material 2 with each other. To also permit stable and efficient formation of a bead in the form of a fillet weld on a back side of a groove by conducting arc welding from the side of the groove without arranging a bead beforehand on the back side of the groove, the first member 1, on which a root face 1a and a single groove face 1b have been formed, is brought at its root face 1a into contact with a flat surface 2a of the second base material 2. A welding wire 6 is arranged facing on the groove formed by the contact between the first base material 1 and the second base material 2. The first base material 1 and the second material 2 are caused to fuse at an area of contact between them by an arc from the welding wire 6. A melt, which has been formed by the fusion at the area of contact and the like, is forced out to the back side of the groove to form a bead B4 in the form of a fillet weld on the back side of the groove.

摘要： In an arc welding method and apparatus, a plasma (13) is generated at a welding intended position on a base material (2) by a laser (16) irradiated to the base material (2). When a discharge electrode (12) is at a minus potential, an arc discharge (4) takes place in the direction of the plasma (13) and is induced at a position irradiated with the laser (16). When the electrode (12) is at a plus potential, arc electrons are generated from a laser irradiated point and discharged to the electrode (12). When a voltage applied between the electrode (12) and the base material (2) is alternating, the polarities of the electrode (12) and the base material (2) alternately change so that the foregoing phenomena alternately occur. When the base material (2) is at a minus potential, an arc discharge (4) takes place from a laser spot. Also, in regard to the arc discharge (4), since the plasma (13) is generated by the laser (16), a stable arc discharge (4) can be generated irrespective of the state of the base material (2) or the state of the electrode (12).

摘要： A narrow gap welding method by which V-shaped or single-bevel grooved multi-layer build-up welding is carried out, comprises the steps of welding a first layer by applying a welding current by which a globule transfer pattern is made into a spray pattern by a waveform in which a direct current and a pulse current are caused to overlap, and thereafter welding the second layer by applying a direct current.
