Abstract
A laser-welding apparatus may include a laser source, an incoming laser beam produced by the laser source, and a beam splitter that splits the incoming laser beam to form a leading beam and a trailing beam. A first focusing lens may focus the leading beam and a second focusing lens may focus the trailing beam to form a trailing-beam pattern on a workpiece. The trailing-beam pattern may include a crescent-shape having arms and a tail portion.
