Abstract
A system and method of friction welding a workpiece. A curl forming die may be disposed proximate a first part and a second part. The curl forming die may form a curl that is generated when the first part is friction welded to the second part.
Claims18
A method of friction welding a workpiece comprising:
- positioning a curl forming die proximate first and second parts that are disposed along an axis, the curl forming die including a first die portion and a second die portion that is disposed opposite the first die portion, wherein the first die portion has a first opening that receives the first part, the second die portion has a second opening that receives the second part, and the first and second die portions cooperate to define a cavity;
- and
- friction welding the first part to the second part such that a first curl is generated proximate the first part and a second curl is generated proximate the second part, wherein the first curl and the second curl are formed by the curl forming die during friction welding, the cavity receives the first part, the second part, the first curl, and the second curl, and the cavity is disposed further from the axis than the first opening and the second opening.
A method of friction welding a workpiece comprising:
- positioning a curl forming die proximate a first part and a second part;
- and
- friction welding the first part to the second part such that a first curl is generated proximate the first part and a second curl is generated proximate the second part, wherein the first curl and the second curl are formed by the curl forming die during friction welding into a thread that extends around the workpiece and the curl forming die is rotated about an axis to unthread the curl forming die from the thread after friction welding the first part to the second part.
A method of friction welding a workpiece comprising:
- providing a first part that has a first hole and a second part;
- positioning a first curl forming die proximate the first part and the second part;
- positioning a second curl forming die inside at least one of the first part and the second part;
- and
- friction welding the first part to the second part such that a first external curl and a first internal curl are generated from the first part and a second external curl is generated from the second part, wherein the first external curl and the second external curl are formed by the first curl forming die and the first internal curl is formed by the second curl forming die.
