Welding and brazing are the metal joining process.Type of joining process to be applied for joining two parts depends on many factors.
WELDING :
>Welding is a process in which both the participating metals are metaled and re solidified to complete as one metal. Proper melting of mating parts is a basic criteria to result a sound weld.
BRAZING :
>In case of Brazing both the participating metals are not melted but a third metal of lower melting point is used to be filled in between the two. The solidification of this third metal results the joining.
>The filler metal is drawn into the gap between the closely fitted surfaces of the joint by capillary action.
>The design of the joint should incorporate a minimum gap into which the braze filler metal will be drawn.
