Solid / Liquid State Bonding<br />

Low temperature joining methods are used when<br />

the metal to be joined cannot withst<strong>and</strong> high<br />

temperature, or intricate sections are to be joined,<br />

or dissimilar metals are to be joined, or<br />

weldability of material is poor.<br />

In these methods, the gap between the metal<br />

pieces to be joined is filled with molten filler<br />

material after heating the base metal. Melting<br />

point of filler material is much lower than base<br />

metals.<br />

The bonding is not due to melting of parent metal<br />

<strong>and</strong> fusion.
