Design and control of new weld interface during welding of dissimilar materials

Features and Uniqueness
  • Welding of dissimilar materials is an important process to manufacture the future structures and devices, but it is hard to produce the high-performance welds because the excessive reaction at the weld interface deteriorates the weld properties. Our group attempts to develop the new dissimilar welding process to yield the new interface with the aimed properties through design and control of interfacial reaction as well as usage of solid-state welding processes, such as friction stir welding and ultrasonic welding.
Practical Application

We hope to have collaborative researches with willing companies for practical application of welding of dissimilar materials, including metal/metal and metal/thermoplastic composite, in transportation, infrastructure, and energy industries.
