Dr. Adam Hehr, Research Engineer at EWI affiliate Fabrisonic, recently published a technical paper, A Comprehensive Review of Ultrasonic Additive Manufacturing. The paper provides a history, technology advancements, application areas and research behind ultrasonic additive manufacturing (UAM). This hybrid 3D metal printing technology uses ultrasonic energy to produce metallurgical bonds between layers of metal foils...

Friction welding, a solid-state process that uses high-speed spindles to weld materials, is notably effective for joining dissimilar materials. EWI has recently developed a new micro-friction welder for small-scale, dissimilar metals joining. The system has been demonstrated on both aluminum-to-titanium and aluminum-to-stainless joints. Application of Micro-friction Welding for Dissimilar Metals, a paper by EWI’s Jerry...
