摘要： The invention relates to a method of welding of at least two metal-based materials (5, 7), non-weldable directly to each other with resistance welding. At least one spacer (6) is joined by welding on at least one of the two surfaces of a material (5) in every interstice between two surfaces of materials to be welded. The welded spacer (6) is utilized so that resistance welding is focused to the surface of the material (5) with the spacer (6) to melt at least one spacer (6) located on the heat affecting zone in order to achieve a weld between the metal-based materials (5, 7).

摘要： The seam welding apparatus includes a pair of rotating electrodes, an electrode supporting frame, a distance measuring means, and a controller. The electrode supporting frame supports the pair of rotating electrodes. The distance measuring means is provided on the electrode supporting frame and measures a distance to an edge of the steel plate. The controller controls the robot to adjust a running direction of the rotating electrodes so that a deviation comes into zero when a distance actually measured by the distance measuring means deviates from a predetermined distance. Thereby, it is accomplished that the seam welding apparatus is downsized as well as uninfluenced by the surface state and/or shape of workpiece (steel plate).

摘要： An electrode orientation checking apparatus includes a machine stand attached to a seam welding apparatus from which one roller electrode of a set has been removed, a positioning guide and a set of distance sensors that are provided on the machine stand, and a calculating section. A positioning surface of the positioning guide is fixed at a position corresponding to a portion of an outer circumferential surface of the one roller electrode before being removed, the portion lying on a line segment connecting rotational centers of the roller electrodes. The distance sensors are respectively fixed forward and backward of the positioning surface in a progression direction of the roller electrodes. The calculating section calculates data for acquiring a direction of the line segment relative to the stacked body.

摘要： An apparatus (10) for joining a predetermined geometrical profile shape from a sheet material (SM) includes a positioning assembly (12) including a base member (14) and a frame (16) that is operable to receive the sheet material (SM), to configure the sheet material in a predetermined orientation and to linearly translate the sheet material along a process direction (20). A Z-bar (22) is configured to guide a first longitudinal edge (FE) and second longitudinal edge (SE) of the sheet material (SM) into adjacent alignment along the process direction (20). A welding and forging assembly (60) welds and then forges a seam between the first longitudinal edge (FE) and the second longitudinal edge (SE) of the associated sheet material (SM).

摘要： A seam welding system includes a pair of roller electrodes. The pair of roller electrodes hold a to-be-welded object between circumferential surfaces of the roller electrodes, rotate while holding the to-be-welded object between the circumferential surfaces, and perform seam welding on the to-be-welded object when a current flows between the roller electrodes while rotating and holding the to-be-welded object between the circumferential surfaces. To an electrode movement mechanism, the roller electrodes are mounted. The electrode movement mechanism moves the roller electrodes along a welding line of the to-be-welded object. Drive sources respectively rotate the roller electrodes and a joint of the electrode movement mechanism. A controller controls an amount by which the roller electrodes rotate based on a torque change in the drive sources so as to keep torques respectively acting on the roller electrodes within a predetermined range.

摘要： A laminate formed by stacking a plurality of workpieces is sandwiched between a pair of roller electrodes. Then, seam welding is performed on the laminate by successively repeating an ON/OFF operation of a conduction state between the pair of roller electrodes while moving the laminate relative to the pair of roller electrodes. When the seam welding stops in a state where the pair of roller electrodes are unpowered and then the seam welding is to be resumed, the laminate is moved by a predetermined distance in a direction opposite to the relative moving direction during seam welding, spot welding is performed on the laminate, and then the seam welding is resumed.
