Solid State Joining of Aluminium to Titanium by High Power Ultrasonics

Abstract:

In this paper selected results about process control and stability during ultrasonic torsion welding of aluminium to titanium sheets are discussed. The process parameters welding force, welding energy and oscillation amplitude were optimized for Al4N/cp-Ti-joints and AA7075/TiAl6V4-joints using modern statistical test methods. The hybrid welds are evaluated and compared based on their mechanical properties. Furthermore thermal characteristics are determined with high resolution during the welding process by thermometry. Central aspects of the current research project are detailed microscopy of the hybrid interface as well as fracture surface analysis to understand the interfacial formation. Relationships between process parameters, joint strength and the related microstructure should be understood.
