This study presents a new method for high-speed joining of the sheet to the end of a tube without the need for any additional processes. Joining of the AA3105 sheets to the AA1170 tube is carried out with a thickness of 0.5 mm. The process is performed using electro-hydraulic forming which is a local deformation of the tube and sheet. In this method, the mechanical force is transmitted by working media in a very short time. The shock wave accelerates the panel sheet towards the die and tube to create a form-t joint. To avoid friction between the mandrel and the at sheet, the panel sheet is pre-drilled. The experimental tests were performed to show the effect of process parameters including; washer housing angle, sheet hole diameter, and the gap between the mandrel and top of the sheet. In addition, pull-out test is utilized to determine the strength of the joints in different conditions. Accordingly, the usage of electro-hydraulic forming on joining thin tubular parts to at sheets was successful and the feasibility of this technique as an advanced joining approach was veri ed.
