What is welding?

Welding is like gluing two pieces of metal together, but instead of using glue, you use heat and special tools.

Imagine you have two toys, and you want them to stick together so they can play as one. If you use a glue gun, that’s easy. But welding is like using a super hot toaster, it melts the edges of the metal, and then they cool down and stick together.

How It Works

When welders use heat, it's like giving the metal a big hug from the fire. The heat makes the metal soft and molten, just like how chocolate gets gooey when you microwave it. Then, the welder uses something called a welding gun or torch to add more metal, which cools down and becomes strong again, now holding the two pieces together.

Why It’s Useful

Welding is used to build things like bicycles, cars, and even bridges. Think of it as a superpower for metals, they can join together forever, no matter how big or small they are!
