Claim 15:
16. An apparatus to facilitate laser welding, the apparatus comprising:
one or more laser welding masks, each laser welding mask comprising:
a guide plate, attached to a load plate, the guide plate defining a plurality of openings that extend from an upper surface to a lower surface;
a plurality of clamp plungers, each clamp plunger disposed within one of the openings in the guide plate, each clamp plunger defining at least one passage configured to pass a laser welding beam; and
a plurality of clamp springs, at least one clamp spring disposed between at least one clamp plunger and the load plate; and
a support base configured to:
position a battery cell carrier below the laser welding masks, the battery cell carrier supporting a plurality of battery cells and a current collector assembly (CCA), and
move the battery cell carrier to align the battery cell carrier and the laser welding masks and to press the clamp plungers of the laser welding masks onto the CCA to clamp the CCA to the battery cells during laser welding.
