Papers abstract:

Some experimental and numerical aspects of the water jet spotwelding are presented in this paper. A 3D finite element simulation is used to simulate the water jet spot welding process and the results are validated using the experimental data obtained previously by one of the authors and others [Salem, S.A.L., Al-Hassani, S.T.S., 1986. Impact spot welding by high-speed water jets. In: Lawrence, E.M., Karl, P.S., Meyers, M.A. (Eds.), Metallurgical Applications of Shock Wave and High Strain Rate Phenomena, Marcell-Dekker, New York (Chapter 53)]. The main objective of the numerical simulation was the identification of parameters, which correlate well with the quality of the welds produced. The results show that the levels of equivalent plastic strain and shear stress directions in the materials predict the success or failure of the welding process.

Product Overview:
The study investigates the water jet spot welding (WJSW) process, combining experimental and numerical analyses. A 3D finite element model is developed and validated using prior experimental data. Key simulation steps include:

• High-speed water jets (650–1200 m/s) were used to weld aluminum, copper, brass, and steel
• The water jet was modeled using hydrodynamic equations and Mie-Grüneisen EOS.
• Finite element results closely matched experimental observations, especially in weld interface characteristics.
• Use ALE Adaptive Mesh Domain to handle large deformations.

In this tutorial, the numerical study of water jet spot welding is simulated, according to data from the work of Chizari et al.
