Vibration Welding Groove

A grooved component shaped for improved bonding of the grooved component with a weld leg via a vibration welding process, the grooved component comprising:

• a groove region comprising a groove, wherein the groove region is located in a joining surface of the grooved component;
• a base region lacking the groove in the joining surface;
• a transition region located in the joining surface between the groove region and the base region, wherein the transition region comprises a tapering of the groove to provide
• a smooth transition from the groove region to the base region;
• and the groove comprises:
• a bottom portion along a mid-line of the groove;
• a profile that ascends symmetrically from the bottom portion to the joining surface on opposing sides of the groove;
• a depression towards outer portions of the groove adjacent the joining surface;
• and
• a hump between the depression and the bottom portion.
