A spinning tool plunges into two pieces of metal, rotating at a high rate of speed. As the tool begins to move, it softens and mixes the metal, creating a powerful weld—one that can securely join ...

Four aluminum domes, created using innovative friction stir welding processes, are seen in this overhead view of the Marshall Space Flight Center Advanced Welding and Manufacturing Facility.

So, wire arc additive manufacturing, or WAAM as folks in the know call it, is pretty neat. It’s basically a fancy way to ...

A breakthrough achieved at a lab in the United States could bring friction stir welding to assembly lines. The technique involves the use of a spinning tool to generate intense levels of deformation ...
