The wide application of light alloys such as magnesium and titanium in industry is closely related to the connection of their heterogeneous structures. As a widely used type of solid-phase welding, ultrasonic spot welding is an effective way to achieve connection of high strength materials. Ultrasonic welding is carried out on magnesium-titanium dissimilar metals to investigate the influences of welding parameters on the joint's tensile property and fatigue property. The analysis of range and variance are a...
