The first step in learning how to forge weld metal is to understand what is going on. Welding metal is a heat and pressure welding process. Heat is used to melt the metal, and pressure from a torch or electric current is used to apply it to the metal
The importance of pressure when using forged welded metal is that it allows you to weld thicker pieces of metal than would be possible if you were only using an arc or gas welding machine. This means that you can create stronger, longer lasting joints between two pieces of different materials (such as steel and aluminum).
