Development of Computational Tools for Predicting Seam Weld Integrity in Thick-Walled Hollow Aluminum Extrusions

The primary goal of this project is to reduce scrap and consumption of primary aluminum during the manufacturing of thick-walled hollow extrusions by developing simulation tools for predicting the quality of seam and charge welds. Upon completion, this project will provide computational methods and acceptance criteria for simulating the extrusion process and using the tools to design process and die modifications that lead to a reduction in scrap.
