SPIN-WELDED ELECTRICAL GROUND AND SPIN WELDING METHODS |
| 摘要 |
A friction-welded ground assembly that includes an alloy substrate with a clearance hole; an aluminum alloy weld nut having a bolt bore and an outer wall; and a grounding bolt. The bore is located substantially within the clearance hole and a portion of the outer wall is joined to the substrate at a friction-welded attachment. Further, the bolt is threaded within the bore. In addition, a method for making a ground includes the steps: rotating an aluminum alloy weld nut having an outer wall at a predetermined speed; lowering the outer wall of the rotating nut into contact with an aluminum alloy substrate to generate a frictional force for a friction time; arresting the rotation of the nut; and applying an axial forging force to the outer wall and the substrate for a forging time. |
