Laser peening

Laser peening is when we use a special machine called a laser to strengthen metal. Think of it like when you eat healthy food to make your body stronger, laser peening helps make metal stronger.

The laser sends out bursts of light that hit the metal really hard. It's like if you hit a wall with your hand, but instead of your hand it's the laser beam hitting the metal.

These bursts of light make small dents in the metal. But don't worry, it's not like when you have a dent in your toy car. These dents are very small and can't be seen without a microscope.

These tiny dents actually help make the metal stronger! When metal gets hit really hard like this, it makes the atoms inside the metal move around. When the atoms move, they can start to stick together better and make the metal stronger.

So, laser peening helps make metal stronger by hitting it really hard with bursts of light, making tiny dents in the metal and allowing the atoms to stick together better.
