Abstract
A pogo welding apparatus especially for spot welding metal sheets at selected locations spaced away from their edges wherein the sheets are held in a temporary assembly with the selected locations engaged and separate programmable positioners move a primary (pogo) electrode and a backup electrode sequentially against opposite sides of the selected locations to spot weld the sheets at the selected locations in sequence. Various alternative programmable positioners, including robots of varying types, may be used to carry the electrodes. A multi head back-up electrode is adapted for efficient use of the apparatus and method in difficult to reach workpiece locations.
