Patent abstract
A method for welding includes providing a pair of substrates with no gap between them. The welding process uses lasers that are moveable through a locus of points relative to the substrates and each other to weld the substrate together. The moveable lasers assist in controlling a formation of a weld keyhole that assists in expelling gases that develop during the welding process.
