Thermite Welding, now I know how it works

What is thermite welding? Thermite welding is the process of joining metals together using a thermite reaction. The thermite heats the metal parts to a very high temperature, and then they’re pressed together to create a molten pool that then hardens. Thermite welding is a type of friction-based joining that can be done without using any flux. The process also does not require the surfaces to have been previously cleaned or prepared in any way, meaning it’s a straightforward and quick technique that won’t take up too much time compared with other metal joining techniques like brazing.
