Standard Robotic Grinding Cells Lincoln Electric

Weld grinding is the removal of excess stock from the weld itself- a process that often results in ergonomic strain on the worker, slower production as well as grinding results that vary. To resolve these issues in the manufacturing industry, Lincoln Electric has teamed up with the abrasive expert 3M in the release of the new Fab-Pak ...

Spent Fuel Pool

Spent Fuel Pool

Spent fuel from nuclear reactors is highly radioactive. Water is good for both radiation shielding and cooling, so fuel is stored at the bottom of pools for a couple decades until its inert enough to be moved into dry casks. We havent really agreed on where to put those dry casks yet. One of these days we should probably figure that out.
