Abstract
A laser welding apparatus having a sky window in a device for pressing two materials together during a welding operation. The pressing device holds a plastic lid material snugly against a plastic container during the welding operation. A laser-transparent window in the pressing device allows a laser beam to be directed through the pressing device to a junction between the lid material and the container. The laser beam is converted into heat to weld the lid material to the container.
