State-of-the-art Joining Methods for Nitinol Shape-memory Alloy — New Paper

By Tim Frech on Tuesday, March 21st, 2017


imageWith applications in multiple industries including medical, sustainable energy, and aerospace, nitinol is one of the most commonly used shape-memory alloys. To take full advantage of nitinol’s shape-memory characteristics, corrosion resistance, and super-elasticity, manufacturers must understand how to join this unique material without detrimentally affecting the properties that make it so attractive.

image2EWI developed a welding process to join nitinol to stainless steel over a decade ago and was recently asked to support a research partner’s program focused on developing mechanical actuators for aircraft wing and rudder control surfaces. A new paper, State-of-the-art Joining Methods for Nitinol Shape-memory Alloy, discusses multiple options for joining of nitinol components, as well as the use of EWI’s patented process for the manufacturing of mechanical actuator demonstrator components.
