Title: On Process, Structure, Property Relationships in Impact Welding of Aluminum 6061 and Steel 4130

Abstract

Vaporizing Foil Actuator Welding process was used to weld 1mm thick aluminum alloy 6061 sheet to 3.2 mm thick 4130 grade steel plate. Temporal evolution of the flyer sheet velocity was recorded at four locations on the flyer sheet using photonic Doppler velocimetry. The welded samples were subjected to mechanical and microstructural characterization. Although the welded interface did not show a very wavy characteristic, the welds had substantial strength. Welds made with a softer temper, T4 alloy were found to be stronger than the one created with a harder, T6 temper alloy. A coupled Lagrangian-Eulerian numerical framework was also utilized to predict the structure of the interface based on the measured velocity profile. The model also depicted absence of large waves although the jetting phenomenon was observed, thereby providing insight into necessary conditions for impact welding.
