Abstract
A method of riveting two metal parts through a hole with an electro-hydraulic riveting tool. The electro-hydraulic riveting tool includes a tube that is inserted in the hole and an electrode that is inserted within the tube. A liquid is contained within the tube and the electrode is immersed in the liquid. A stored charge is discharged through the electrode to create a shockwave within the fluid that forms the tube into a rivet structure and creates solid state weld between the rivet flanges and the parts that are joined.

A rivet for securing together two parts that define a hole comprising:
- a tubular member that extends through the hole from a first side of the two parts to a second side of the two parts, the tubular member having a first flange that engages the first side and a second flange that engages the second side;
- and
- a first solid state weld formed between the first flange and the first side and a second solid state weld formed between the second flange and the second side.
A riveted assembly comprising:
- a tubular rivet attaching a first part defining a first hole to a second part defining a second hole, the rivet extends through the holes and includes a first flange engaging the first part and a second flange engaging the second part;
- a first solid state weld formed between the first flange and the first part;
- and
- a second solid state weld formed between the second flange and the second part.
