The Tucker No Hole fastening solution utilizes a drawn arc welded stud to a component that then enables fastening utilizing a plastic clip or threaded nut, whatever best works for the application. This fastening solution provides superior performance to punching/stamping a hole in a component and then fastening to that hole with regard to Sealing, NVH (Noise Vibration Harshness) and often ergonomics. The Drawn Arc welding process itself is superior to many other welding processes as it only requires accessibility to one side of the component and has the required Reliability and Repeatability to be used in Automated systems often using robots.
Drawn-arc stud welding provides numerous fastening options and is widely used for a variety of attachment needs.
Automatic feeding and one-sided welding of nuts to sheet metal provides more possibilities for complex processing demands.
Robust mechanical joining of sheet materials is achieved by inserting a rivet and cold-forming an interlock with cycle times similar to spot welding.
