  • Apparatus for controlling the welding pattern between weldment components
    Patent number: 4056705
    Abstract: An arrangement for actuating welding guns to weld weldment components in a predetermined welding pattern wherein the weldment components are movable relative to the welding guns. Movable means are movable in synchronism at a predetermined reduced speed in relation to the speed of the movable weldment components with means on the movable means corresponding with the desired welding pattern to be formed on the weldment components. Scanner means are electrically connected to the welding guns and are responsive to the indicating means to sequentially activate and deactivate the welding guns to weld the weldment components and form the predetermined welding patterns thereon. Limit switch means are electrically connected to the welding guns and means are provided on the movable means to actuate the limit switch means when the weldment components have completed their movement relative to welding guns to deactivate the welding guns.
