Abstract
A method of laser welding aluminum alloy workpieces with dual laser beams arranged in a cross-beam orientation is disclosed. The method comprises directing dual laser beams, which include a first laser beam and a second laser beam, at and along a weld seam established between the aluminum alloy workpieces together with a filler wire. The first laser beam includes a first longitudinal axis and the second laser beam includes a second longitudinal axis. When arranged in the cross-beam orientation, a plane that intersects the first longitudinal axis and the second longitudinal axis of the first and second laser beams, respectively, forms a line where it meets the aluminum alloy workpieces that is oriented transverse to the weld seam.
