Abstract
A method and arrangement for spot welding the anode structure of a succession of alkaline primary batteries with a focused beam of radiation generated by a stationary laser as the batteries are conveyed through the arrangement. The batteries are conducted along a circular work station in the form of a star wheel having the batteries arranged around a portion of its circumference. An optical focusing system is mounted for oscillation about the rotational axis of the star wheel in synchronous motion with each battery as it passes through the beam of radiation. The anode structure of each battery is positioned at the focal point of the optical focusing system whereby the optical focusing system focuses the radiation beam on one small area of the anode structure to produce a spot weld on the anode structure.
