Claim 17:
18. A method of joining electric motor stator wiring, the method comprising:
evaluating weld joints between hairpin wire connections of a stator winding with an electronic vision system;
determining mismatch between each of the hairpin wire connections with the electronic vision system and transmitting at least one mismatch parameter to a laser welding system for each of the hairpin wire connections;
laser welding linear weld segments biased towards but not overlapping a joint line between each of the hairpin wire connections by melting the linear weld segments during a first welding step and forming a weld across the joint line as a function of the at least one mismatch parameter; and
oscillatory welding over the joint line between each of the hairpin wire connections during a second welding step.
