1. A resistance welding electrode comprising:

  • (a) a hollow metal shank having a circular hole at one end perpendicular to its axis, such that a metal pin when inserted through extends on both sides of the said shank as a projected metal pin; and

    (b) a metal tip contaning two diagonal notches, which lead into two diagnol grooves and ends in a hole, which act as leads for the said protected metal pin and allows the metal tip to be guided and retained in position onto the metal shank, when the metal tip is slightly twisted over the said metal shank with the projected metal pin and thus when the said metal tip abuts against a metal workpiece, during welding, the said metal tip gets locked to the said shank by the projected metal pin.
