A traction battery includes a stack of cells each having two terminals. Sets of terminals are connected to busbars to electrically connect the battery cells. The busbars have a base, a set of connecting portions, and a set of stiffeners. The terminals have protruding portions and receding portions. As the busbar is positioned with respect to the battery stack, the connecting portions guide the receding portions into position by deflecting the protruding portions. The receding portions are then welded to the connecting portions. The deflected protruding portion forces the parts to be welded together, eliminating a need for clamping during the welding process.
