Electron beam welding

Electron beam welding is when we use an ultra-thin beam of electrons to melt metal together, kind of like how we use glue to stick two pieces of paper together. The electrons are like really tiny particles that we can't even see with our eyes, but they are very powerful!

We make the electron beam by heating up a special metal called tungsten, which creates a cloud of electrons around it. We then use magnets to focus those electrons into a single, tiny beam.

When we aim the electron beam at two pieces of metal we want to weld together, the heat from the electrons causes the metal to start melting. This allows the two pieces of metal to mix together and form a strong bond when they cool off.

One reason why electron beam welding is so great is that we can use it to weld even the thinnest pieces of metal together without damaging them. It's also much faster and more precise than other welding methods, which means we can create stronger and more complex parts for airplanes, rockets, and other machines.
