Interlocking tubes and laser welding create high-strength, lightweight panel structures.
A new way of forming lightweight sandwich panels has been developed by TWI, the industrial fastening research group.
Machined or extruded tubes form the interior of the sandwich. On the outer surface of each tube are simple male and female connections in the form of studs or slots. Once connected, the tubes become mechanically locked in a solid array in the X-Y plane. External skins are stake welded to the top and bottom of the array using a CO2 or Nd/YAG laser to penetrate the material from the outside. The result is a high-strength sandwich panel, rigid in all three directions.
TWI has given the name Ex-Struct™ to the concept. Materials that may be used in its manufacture include steel, alloys, and plastics.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
