Abstract
A laser welding apparatus comprises a mount attached to a laser beam delivery system and a cylinder attached to the mount. A piston having first and second piston ends and a piston body sealingly and slidably engages with the cylinder dividing the cylinder into first and second piston chambers. The piston is slidable between an extended position and a retracted position and has a central axial bore through which a supplemental wire is fed. A wire supply provides supplemental wire to the first piston end and a delivery head attached to the second piston end delivers the supplemental wire proximate to a laser beam and a work-piece.
