The force applied to the electrodes in making spot, seam, or projection welds by resistance welding. See also DYNAMIC ELECTRODE FORCE, STATIC ELECTRODE FORCE, and THEORETICAL ELECTRODE FORCE.
Dynamic. In spot, seam and projection welding, the force (pounds) between the electrodes during the actual welding cycle.
Theoretical. In spot, seam and projection welding, the force, neglecting friction and inertia, available at the electrodes of a resistance welding machine, by virtue of the initial force application and the theoretical mechanical advantage of the system.
Static. In spot, seam and projection welding, the force between the electrodes under welding conditions, but with no current flowing and no movement in the welding machine.
