INERTIA AND FRICTION WELDING OF TYPE 1100 ALUMINUM TO TYPE 316 STAINLESS STEEL

摘要

The inertia and friction-welding processes were evaluated for joining Type 1100-H14 aluminum to Type 316 VIM VAR stainless steel. While both processes consistently produce joints whose strength exceed the aluminum base metal, 100 percent bonding has not been reliably achieved. This difficiency points out the need for the development of nondestructive testing techniques for this type of joint. Additionally, solid-state volume diffusion did not appear to be a satisfactory explanation for the inertia and friction-welding bonding mechanism.
