Dissolution of base metals can cause detrimental changes in the brazing alloy.
The pin tip, brazing alloy, flux and lug cool into a homogenous unit.
The braze alloy joins the materials and compensates for the difference in their expansion rates.
Of all the brazing alloys, silver solders have the greatest strength and the broadest applications.
Brazing alloys used include 3565 AuCu and 5050 AuCu, which are used in a dry hydrogen atmosphere.
The effect works both ways; there can be detrimental interactions between the braze alloy and the base metal.
Brazing with silver based braze alloys can lead to problems due to the excessive diffusion of silver along grain boundaries.
Finally, the braze alloy joins the other two materials to create a composite structure, much as layers of wood and glue create plywood.
Presence of phosphorus in the braze alloy leads to formation of brittle phosphides of iron and nickel, phosphorus-containing alloys are therefore unsuitable for brazing nickel and ferrous alloys.
This is done using the twin wire-arc spray process where the wire is the braze alloy, deposited on the tube as it is being manufactured at 200-400 fpm.
