Abstract: A vibration welding groove system may include a first component having a joining surface with a groove region, where the groove region comprises a groove formed in the joining surface. The first component includes a base region lacking the groove in the joining surface and a transition region located between the groove region and the base region. The transition region has a tapering of the groove to provide a smooth transition from the groove region to the base region. The vibration welding groove system may further include a second component having a weld leg extending from a main body, where the groove of the first component comprises a shape configured to nudge the weld leg towards a center of the groove during joining of the first component with the second component.
