Metal flow in idealised a-symmetric 2D extrusion welding
Source abstract
Abstract
It is common in aluminium extrusion industry to use extrusion dies that have portholes to produce hollow profiles. When the hollow profiles are to be produced with such a shape that different sections vary in thickness then usually dies with portholes of different sizes are used. A study has been performed in order to analyze metal flow in cases where two neighbouring porthole channels at each side of a die bridge are of different size. The study shows that there is of course more feed through the larger porthole, and that this effect has a significant influence on the deformations and metal flow in the region behind the bridge where the two metal streams meet and are joined together into an extrusion seam.
