ABSTRACT:
A method for making an electrochemical device enclosure is described. The methods comprises the steps of forming first and second casing members; inserting electrochemically active materials within the first casing member; mating the first casing member to the second casing member, thereby forming an interface therebetween; providing a laser welding apparatus comprising a laser; intermittently turning a laser beam on and off while traversing the laser in a first welding pass 360 degrees along the perimeters of the first and second casing members, thereby forming a first intermittent set of welded and unwelded sections at the interface between the casing members; and intermittently turning the laser beam on and off while traversing the laser in a second welding pass 360 degrees along the perimeters of the first and second casing members, thereby forming a second intermittent set of welded sections at the interface between the first and second casing members. The first and second intermitted welded sections combine to provide a complete hermetic seal around and along the circumference of the casing members interface.
