KHI Opposing RFSJ Robots

Friction stir spot welding (FSSW) is a state of the art joining technology and it is achieved by generating friction heat through the rotation of the joining tools, resulting in softening of the materials, allowing the pieces to join together. Kawasaki's FSSW technologies called as "FSJ™".  This prototype system includes two of a highly rigid robot MG10HL, the right robot has FSJ™ gun and the left robot has anvil gun. The sample placed between two robots simulates a part of fuselage of aircraft.  This system demonstrates RFSJ™, which is advanced FSJ™ and can achieve flat surface without exit hole.

Mazak’s HYBRID Multi-Tasking Series

Dale Fleck, general manager of Mazak MegaStir, explains the technology behind Friction Stir Welding (FSW) and how it fits into Mazak’s HYBRID Multi-Tasking Series.



SKB Encapsulation Plant for Spent Nuclear Fuel

Before the spent nuclear fuel is transported to the Spent Fuel Repository at Forsmark for final disposal it will be encapsulated in copper and nodular cast iron. This is planned to take place in an encapsulation plant to be built next to the interim storage facility at Oskarshamn.  Spent nuclear fuel is highly radioactive. In order not to cause harm, the fuel must be kept isolated from man and the environment for a very long time. The solution is a final repository at a depth of nearly 500 metres, where three different barriers prevent the radioactive substances (radio-nuclides) in the fuel from reaching the ground surface.

USPTOvideo Science of Innovation

Welding has long been used to join pieces of metal together. At the University of North Texas, Rajiv Mishra is using a form of welding in a new technology that can improve metal’s strength, toughness, and other properties and could bring new opportunities to the automotive and aircraft industries.
