HIP brazing

HIP-assisted brazing utilises the fabrication method of encapsulation and hot isostatic pressing to form a superior braze bond. The braze material will be in the liquid state for at least part of this process to ‘wet’ the parts to be joined and fill in gaps. Some alloying occurs with the materials to be joined although they remain in the solid state. Some brazes are transient liquid phase meaning that their composition changes during the brazing process as they alloy with the parts to be joined; this results in a bond that is more stable at higher temperatures than the original braze material was.
