摘要： This method for designing a laminate molded article involves using shape data of a laminate molded article to perform layer decomposition of the shape of the laminate molded article at each bead height per layer of weld bead layers, and perform layer decomposition to generate a plurality of virtual bead layers. Next, at an intermediate layer disposed at the lamination-direction center of the plurality of virtual bead layers, a direction in which the layer-decomposed laminate molded article continuously extends is set as a reference direction. The bead size of a weld bead formed in the plurality of virtual bead layers is then adjusted by a bead shape in a cross-section orthogonal to the reference direction.

摘要： The present invention provides: a joining method and a structure for a laminate shaping component that can be manufactured easily and with high quality without limitations to the size or the complexity of the shape of the laminate shaping component; and a laminate shaping component. This laminate shaping component is shaped by repeatedly laminating a subsequent weld bead layer on a weld bead layer that is formed in weld beads in which a filler material is melted and coagulated using arc welding. The plurality of laminate shaping components are welded together by interposing therein laminate layers and shaped welding joints to form an integrated structure.

摘要： The invention relates to a welding assembly for the permanent joining of a first tubular component with a second component along a two- or three-dimensional intersection curve, along which both components contact, comprising a securing assembly for detachably securely joining on a tubular end of the first component facing away from the intersection curve, a manipulator unit mounted directly or indirectly on the securing assembly such that it can pivot about a tube longitudinal axis assigned to the first component, said manipulator unit having a freely positionable manipulator end, as well as comprising a welding tool attached to the freely positionable manipulator end, wherein the securing assembly comprises a clamping module that can at least partially be introduced into the tubular end of the first component on the end side and in an axial manner, which clamping module is designed for detachably securely joining onto a tube inner wall assigned to the first tubular component, as well as a carrier ring module which is rotatably attached to the clamping module, which axially extends beyond the tubular end of the first component in the joined state of the clamping module, and which is in operative connection with a servomotor for the rotary driving of the carrier ring module about the tube longitudinal axis, in such a way that the carrier ring module is mounted such that it can rotate continuously about the tube longitudinal axis. In addition, at least one linear frame is attached to the carrier ring module, which frame is mounted such that it can be moved bidirectionally and parallel to the tube longitudinal axis by means of an actuator. The invention is characterised in that the manipulator unit is a 6-axis open kinematic chain in the form of a vertical articulated robot and is attached to an end of the frame, and in that a supply module is provided on which at least one of the following components is attached: a control unit, an electrical energy supply unit, at least one reservoir for the material relating to the welding process, comprising welding wire and process gas. In addition, the at least one component is connected to the welding tool via a connection line. The supply module is rotatably mounted for performing a rotational movement at the same time as the movement of the welding tool about the tube longitudinal axis, which permits infinite rotations of the welding tool about the tube longitudinal axis. The supply module is connected, in a rotationally fixed manner and such that it is linked in a freely positionable manner along a plane, to the carrier ring module on a support structure formed separately to the welding assembly.

摘要： A welding location progresses along a weld path by arranging relative motion between a welding head and workpieces. A controller controls the actuator to correct transverse deviation of said weld location relative to a target position on said workpieces. A monitoring apparatus comprises a workpiece tracking sensor configured to observe a shape profile of the workpieces in the vicinity of the welding location and a weld tracking sensor for obtaining a thermal profile of the workpieces, at a location downstream of the welding location. The apparatus compares observations made by the two sensors in a common reference frame, to detect and correct transverse deviation of the welding location relative to a target position on the workpieces. The apparatus may be applied in a spiral pipe mill.

摘要： Pipes (10, 11) for building off-shore structures frequently have complex, three-dimensional intersection curves (12). For welding the pipes (10, 11) along the intersection curve (12), which is traditionally carried out mechanically, a welding material (18) is moved along a rail (14) that is detachably fastened to a pipe (10). The rail (14) has to be individually adapted to the progression of the welding seam (13) connecting the pipes (10, 11) at the intersection curve (12). This requires differing rails (14) for a respective intersection curve (12), or welding seam (13). According to the invention, a mobile robotic device (16) arranged on the rail (14) is provided, to which the welding material (18) is allocated. In this way, even complex, three-dimensional welding seams (13) can be formed using a straight rail (14), which can be used universally for differing welding seams (13) having diverging progressions.

摘要： The invention relates to a method for producing welded helical-seam tubes (10) having optimized tube geometry. A metal strip (1) is helically shaped into an open seam tube by means of a forming unit (11) and the converging strip edges are welded together, wherein an actual diameter determined on the welded tube is compared with a specified target diameter and any deviation lying outside a tolerance threshold is used to correct the actual tube diameter, wherein the strip edges are completely welded in a two-stage step, comprising tack welding as a first step immediately after the shaping to form an open seam tube and thereafter final welding as a second step. According to the invention, the tube diameter is measured after the complete shaping to form an open seam tube and before the final welding. For this purpose, the diameter measuring device (8) is arranged in such a way that either the completely shaped open seam tube or the only tack-welded tube is measured.
