Friction stir welding joins previously unweldable materials. Friction stir welding, a relatively new process, is having a tremendous impact on welding dissimilar alloys. It was developed in 1991 by ...

Friction stir welding (FSW) is not necessarily a new welding process, but the implementation of it was slowed significantly ...

Retention of material properties: Minimizes material distortion. Safe operation: Does not create hazards such as welding fumes, radiation, high voltage, liquid metals or arcing. No keyholes: Pin is ...

You’d think writing for Hackaday means we probably don’t get surprised very often by projects… but then we see something we never thought was possible — in this case, the linear friction welding of ...

Lockheed Martin has begun its first friction stir weld process on an Orion crew module Ground Test Article at the NASA Michoud Assembly Facility in New Orleans, La. This ground test article will serve ...

This car door was made stamped out of a blank of aluminum made up of a heavy-gauge piece of aluminum joined to a lighter-gauge sheet. The heavier metal was used on the right side of the door (white ...

Although some engineers have had success in spot welding steel and aluminum together, it has largely been considered impossible to achieve reliable, continuous welds directly between the two ...
