A laser welding head capable of producing a plurality of beams that are proficient in providing a unique keyhole. The welding head is movable through a plurality of positions relative to substrates that enables the plurality of beams to engage the substrates in a manner that welds the substrates in a variety of stack-up positions. A welding method using the welding head is also provided.

Dual beam laser welding head

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.
