Abstract: 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.

Abstract: A power pack assembly, usable for example in welding, having a transformer, includes at least a pair of rectifier units coupled to secondary conductors thereof. The rectifier units each includes a spaced pair of substantially parallel mounting plates having a plurality of diode stacks sandwiched therebetween. One of the mounting plates is segmented between each pair of diode stacks to permit flexing of the resulting segments thereof axially of the diode stacks. Means are provided for clamping the mounting plates fixedly with respect to each stack of diodes, whereby the flexibility of the segments of the segmented plate allows same to accommodate to varying axial dimensions of the several diode stacks.

Abstract: RESISTANCE WELDING SYSTEM FOR PROJECTION WELDING A resistance welding system having a low-inertia movable welding head coupled to a stationary welding transformer which is of low mutual reactance. Through an appropriate timing circuit and control, a high-energy pulse of current, of very short time duration, is transmitted through the welding transformer to the movable welding head. The welding head, which contacts a projection on overlapping components, effects a rapid welding of the components, and the welding head rapidly follows up the melting of the projection due to its low inertia.

Abstract: A rotatable member is mounted through substantially normal bearing structure onto a shaft in rotating relationship therewith. A torque limiting drive device, such as a spirally coiled spring, is fitted between the rotable member and the shaft for permitting transmission of torque therebetween. The spring permits only a limited torque to be transmitted between the rotable member and the shaft such that, if this torque is exceeded, then the spring slips with respect to the rotable member to thereby permit relative rotation between the shaft and rotatable member.

Abstract: A projection coined onto a metal sheet, 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 of the projection surrounds a first recess and a second recess 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.

Abstract: A manufacturing system applicable to seam welded metal containers for the fastening of attachments thereto in a predetermined relationship to the seam. The container is supported upon suitable means for rotating same about its longitudinal axis and a mechanically actuated feeler switch is arranged thereagainst for responding to the increased thickness of material in the location of the seam and delivering a signal. Said signal initiates a timer control which stops the rotation of the container at a predetermined angular spacing from the seam and initiates the attaching operation which latter may occur in the same or at a subsequent station.

Abstract: Seam welding apparatus (50) with a bearing support arrangement for a transversely movable upper welding wheel (51). The upper wheel is nonrotatably 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.

Abstract: CONTINUOUS MOTION CIRCUMFERENTIAL SEAM WELDER 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 for causing rotation of the workpiece through approximately one half revolution, whereby the two electrodes simultaneously form two welds which are about 180.degree. apart and which may individually extend up to a total angle of rotation of about 180.degree., or slightly in excess thereof, so that the welds overlap.
