混合轻量化结构塑造了交通工程和航空航天工业中未来车辆的发展。对于由铝和钛合金制成的多材料概念，超声波焊接技术是一种替代的有效连接技术。重叠的结构可以在固态下焊接，即使没有气体保护。在本文中，传统的超声点焊与纵向振荡模式与最近的超声扭转焊接与扭转模式在20 kHz的工作频率进行了比较。对于每种技术的工艺参数焊接力，焊接能量和振动振幅进行了优化的混合接头使用实验设计。应了解工艺参数、机械性能和相关焊接区之间的关系。该研究项目的核心方面是横截面连接区的微观研究和广泛的断裂面分析。详细的电子显微镜和光谱的混合界面有助于了解超声波焊接过程中的界面形成，以及转移所获得的知识，为进一步的多金属接头。
Hybrid lightweight structures shape the development of future vehicles in traffic engineering and the aerospace industry. For multi-material concepts made out of aluminum and titanium alloys, the ultrasonic welding technique is an alternative effective joining technology. The overlapped structures can be welded in the solid state, even without gas shielding. In this paper the conventional ultrasonic spot welding with longitudinal oscillation mode is compared to the recent ultrasonic torsion welding with a torsional mode at 20 kHz working frequency. For each technique the process parameters welding force, welding energy and oscillation amplitude were optimized for the hybrid joints using design of experiments. Relationships between the process parameters, mechanical properties and related welding zone should be understood. Central aspects of the research project are microscopic studies of the joining zone in cross section and extensive fracture surface analysis. Detailed electron microscopy and spectroscopy of the hybrid interface help to understand the interfacial formation during ultrasonic welding as well as to transfer the gained knowledge for further multi-metal joints.
