A method for simultaneously cutting and welding ultra-thin foils having a thickness of less than 0.002 inches wherein two ultra-thin films are stacked and clamped together. A pulsed laser such as of the Neodymium: YAG type is provided and the beam of the laser is directed onto the stacked films to cut a channel through the films. The laser is moved relative to the stacked foils to cut the stacked foils at successive locations and to form a plurality of connected weld beads to form a continuous weld.
A method of lap or side by side lap welding ultra-thin metal foils having a thickness of less than 0.002 inches comprising: a) providing a first ultra-thin foil having a thickness of less than 0.002 inches, b) providing a second ultra-thin foil having a thickness of less than 0.002 inches, c) placing one of the ultra-thin foils on top of the other ultra-thin foil so that the foils are arranged in a stacked configuration, d) clamping the first and second foils together in a stacked configuration, e) providing a laser having a focused beam, f) directing th...
