Ultrasonic Stir Welding Technology Demonstration

Solid state welding technology has just experienced a breakthrough using ultrasonic energy. In this Ultrasonic Stir Welding system, sound energy is generated by two transducers then transmitted to the containment plate and stir rod. This energy reduces plunge, shear, and frictional forces, increasing the life of the pen tool and providing a significant increase in […]

Science of Innovation: Friction Stir Welding

From building bridges, to erecting skyscrapers, to assembling airplanes and cars, welding allows engineers and manufacturers to connect metal structures. But the method of joining metal to metal through melting had remained mostly the same for decades. That is, until 1991, when a new kind of welding was invented. Instead of melting metals to connect […]
