The brazing between nickel and aluminium plates is a very sensible process being influenced by type of used materials and by brazing devices which maintain in contact the metal plates. These brazing devices have a very important purpose, their pressure affect directly the capillarity force. If the brazing devices are too tight (like 7 bar pressure), the filler melted metal escape from the grip, causing presence of defects in the joint; if the brazing devices are not tight enough (like 5 bar pressure) the capillarity forces become weak, allowing the voids inside the joint. Therefore, it’ is optimal for a nickel-aluminium brazed joint without defects a 6 bar pressure, created by brazing devices,
