摘要： Seam welding apparatus (50) with a bearing support arrangement for a transversely movable upper welding wheel (51). The upper wheel is non-rotatably secured adjacent one end of an elongate electrically conductive shaft (66), the other shaft end being rotatably supported within an electrically conductive bearing assembly (67) which transmits electricity thereto from an external source (63). A non-rotatable bearing housing (68) is pivotally supported relative to a machine frame (61) by a pivot (74) which extends adjacent the housing perpendicularly to the shaft, the pivot being disposed remote from the wheel. A pressure cylinder (81) and ram (82) are mounted on the frame, the ram being movably supported and acting downwardly onto a spring unit (83) and electrical insulator (84). The spring and insulator are rotatably supportingly engaged with the shaft adjacent the wheel. The housing and shaft are mounted on a movable slide (73) to which the ram is preferably coupled. The spring unit is coupled between the slide and shaft.

摘要： A welding head for projection welding wherein the spring which biases the electrode is initially preloaded to exert a significant biasing force on the electrode to maintain it against a stop to define the normal fully extended position of the electrode. The spring of the welding head is also initially precalibrated to exert an accurate predetermined biasing force on the electrode when the electrode is depressed inwardly so as to effect compression of the spring by a predetermined distance, which latter distance is of very small magnitude. The welding head is disposed in engagement with overlapping sheets so that the electrode is engaged with the sheets in alignment with a projection thereon, and the electrode is depressed through said predetermined distance so that a uniform predetermined biasing force is applied to the electrode and hence to the projection weld area.

摘要： A projection coined onto a metal sheet (52), preferably an aluminum sheet, for projection welding the sheet to an adjacent metal sheet. The projection has a thickness greater than the thickness of the sheet on which it is formed. The wall (55) of the projection surrounds a first recess (1) and a second recess (63) is formed in a side of the sheet opposite the projection from which the metal cold flows to form the projection. A welding gun assembly having an improved low interia, fast response to the collapse of the projection welding the sheet having the projection to the adjacent sheet.

摘要： A method and apparatus for creating a circumferential seam weld in surrounding relationship to a cylindrical workpiece. The workpiece is moved continuously along a work path at a preselected velocity, and is simultaneously supported for free rotation about its longitudinal central axis. The workpiece moves into engagement with opposed surfaces defined by a pair of electrodes, one of which moves relative to the other and relative to the workpiece through approximately one-half revolution, whereby the two electrodes simultaneously form two welds which are about 180° apart and which may individually extend up to a total angle of rotation of about 180°, or slightly in excess thereof, so that the welds overlap.
