Abstract: A system for welding together tips of different wires arranged about a motor stator. A scanner control module is configured to operate a three-dimensional scanner to scan the tips of the different wires and measure alignment of the tips in X, Y, and Z directions of a coordinate plane. A system control module is configured to compare the measured alignment of the tips to a predetermined alignment range, and configured to identify a weld schedule for each of the tips that fall within the predetermined alignment range. A laser welder control module is configured to operate a laser welder to weld together only the tips aligned within the predetermined alignment range in accordance with the weld schedule identified by the system control module.

Abstract: A method of forming a weld interface between a first workpiece and a second workpiece includes arranging a reactive braze material at a first joining surface of the first workpiece. The reactive material is selected to react upon being heated to a temperature below the solidus temperature of the first and second workpieces to form a liquid-containing reaction product. Furthermore, an assembly is prepared of the first workpiece and the second workpiece with the first joining surface of the first workpiece and a second joining surface of the second workpiece separated by the reactive material. The second workpiece is then heated with a first laser beam following a first path and with a second laser beam following a second path.
