What Is Forge Welding?

Forging, also known as forging welding, casting welding, and forging welding, is a solid state welding process. First, two pieces of metal are heated to reach the incandescent state, and then they are fused and repeatedly welded together by hammering.

Forging also known as forging,

This is the simplest metallurgy technology, and it has been applied by humans for a long time. Forging is widely used, it can fuse two different metals with similar melting points. in

The temperature required for forging is usually only 50% to 80% of the melting point of the metal. Steel requires lower temperatures than iron. When forging, the metal surface needs to be smooth or wet. But be careful to avoid overheating, which can cause rapid oxidation and sparks from combustion.

The redox reaction will reduce the quality of forging. In order to make forging welding easier, a flux such as borax can be coated on the two metal surfaces to prevent the redox reaction and improve the quality. When the flux and oxide are mixed together, a thin film is formed, reducing the viscosity of the oxide. When two pieces of metal are joined together and beat, the oxide mixed with flux will flow out of the joint surface, which can reduce the fusion temperature.
