Brazing is a joining process where a metal, having a lower melting temperature than the parts to be joined, is placed in between when molten in order to achieve a metallurgical joint by diffusion. The brazing metal, or alloy, is called the filler is the only one undergoing a transformation; both parts keeping their original shape. Brazing has a very broad scope of applications; it is widely used in the industry (aerospace, automotive, electronics, etc.), Med-Tech, Watchmaking and jewelry since centuries. Unless other joining techniques, it can be used on almost every material, dissimilar metals and even ceramics.
