Paper Title:
Numerical Investigations of Welding Conditions during Extrusion of 2024 Alloy through Porthole Dies
  Abstract

In the work, numerical calculations of extrusion process of 2024 alloy through porthole dies were performed. The DEFORM 3D program based on Finite Element Method was used. The way of metal flow, distributions of stresses as well as temperature level within the welding chamber were predicted for different geometry of porthole die. Particularly, different height, width, and shape of the welding chamber were adopted in calculations. The calculations allowed predicting both hydrostatic pressure and temperature levels as well their distributions in the welding region providing the best welding conditions for the alloy tested.
