As part of a larger program to establish statistically validated mechanical properties for E357-T6 sand castings, this weld repair study was designed to consolidate industry best practices to establish an AFS Recommended Practice for the in-process weld repair of aluminum-silicon hypoeutectic alloys, develop mechanical properties to demonstrate the efficacy of the practice, and develop statistical data that facilitates acceptance of the weld practice.
The research team will develop a practice for in-process weld repair of aluminum-silicon hypoeutectic alloys, track the mechanical properties to demonstrate the effectiveness of the practice and provide a statistical basis for acceptance.
