Effect of a Welding Method on the Fatigue Strength and Fracture of Foam–Aluminum Sandwiches

Abstract—The influence of argon-arc welding and laser welding on the fatigue properties and the fracture of a foam–aluminum sandwich is studied. Argon-arc-welded samples are found to have the highest fatigue strength.
