Abstract: A multi-pass welding method is provided for minimizing bead sagging and forming a welded joint having a good weld metal surface, even during multi-pass welding in a horizontal orientation, and a multi-pass butt welded joint and a lamination pattern calculation method for a multi-pass weld formed by the method. The weld metal has a plurality of layers from the rear surface of a base material to the front surface thereof. The plurality of layers include a finishing layer having at least two layers including an end layer; and a ground layer for forming the finishing layer. A boundary layer, which is the layer of the ground layer adjacent to the finishing layer, is formed such that the position of an upper plate-side weld is closer to the front surface of the base material than the position of a lower plate-side weld.

Abstract: A welding method includes feeding a welding electrode axially from a welding torch, moving the welding electrode radially in a desired pattern with respect to a central axis of the welding torch by a motion control assembly within the welding torch, transmitting from control circuitry a signal corresponding to a position of the welding electrode relative to a weld joint or weld pool, advancing the welding torch or a workpiece to establish a weld, and transferring material from the welding electrode to a first location in an area of the weld pool. The welding electrode moves radially while feeding the welding electrode from the welding torch, the material from the welding electrode is transferred to the first location during a first cycle of the desired pattern, and the first location is controlled based at least in part on the signal.

Abstract: 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.

Abstract: A method of producing a stabilizer (10) of a motor vehicle, such that the stabilizer includes a torsion bar (11) and longitudinal links (12, 13). The longitudinal links (12, 13) are in each case connected to the torsion bar (11) by welding, and the longitudinal links (12, 13) and the torsion bar (11) are heat-treated before welding. Each longitudinal link (12, 13) is welded at one end to the torsion bar (11) on both sides, in each case, by a respective multilayer weld seam (14), and each weld seam (14) is made with unequal widths such that the width of the weld seam (14) adjacent to the torsion bar (11) is shorter than its width adjacent to the respective longitudinal link (12, 13).

Abstract: The present invention provides an arc welding control system and method capable of simultaneously, sophisticatedly performing a weaving width control operation and a torch height control operation. Influence ratios (δw and δz) of influences of a torch height deviation (ΔPh) and a groove wall distance deviation (ΔPd) with respect to a manipulated variable (Δw) of a weaving width and a manipulated variable (Δz) of a torch height are set in accordance with a groove angle (θ) of a workpiece (5). A calculation unit (21) calculates the manipulated variables (Δz and Δw) of actuators (13 and 14) regarding the torch height and the weaving width such that the influence ratios (δw and δz) become large as the groove angle (θ) becomes large.

Abstract: A welding device applies weld material between two work pieces such that the work pieces are connected mechanically with one another. The welding device includes a welding head and a central element. The welding head performs a welding action during transport thereof along an operating direction between the work pieces. Two primary sensor members are arranged on the central element upstream of the welding head relative to the operating direction. The sensor members register geometric properties of a spacing between the work pieces in which spacing the weld material is to be applied. Each sensor member is configured to maintain contact with a respective wall of the two work pieces adjoining the spacing while allowing variation of lateral distances between the central element and the adjoining wall. This is accomplished by the sensor members being pivotally attached to the central element via at least one pivoting axis oriented essentially perpendicular to the operating direction.

Abstract: The welding torch performs oscillation of the torch head while moving the torch head along the circular weld path, under control of signals generated by a controller. The operator of the welding torch preferably has control over the amplitude of the oscillation, how fast it moves back and forth, and how long it remains at each turning point of the oscillation (dwell time).
