Brazing is a highly versatile and cost-effective high-temperature method to permanently join a wide range of heat- and corrosion-resistant alloys for service in diverse industries.

During any braze process, the temperature of an assembly is raised high enough to melt a brazing filler metal (BFM) placed in, or next to, a joint in that assembly that is to be permanently joined together when the BFM melts and flows into the joint by capillary action.

We furnace-braze a cylindrical bar into a mating hole in a larger cylindrical part using AMS 4774 silver-based brazing filler metal.

An answer to a query of which surface in the joint should be plated when vacuum brazing a metal to another superalloy.

It is well known that the warmer the gas, the greater the amount of moisture that gas can hold.

Radiography is often used by some companies for inspection of their brazed components, but its use is sometimes not appropriate, especially when the parts being inspected are thick.

Perhaps this is a good time to describe the brazing and soldering processes in more detail so that readers can understand the significant differences between them.

We are brazing both Inconel 718 and Haynes 214 in our vacuum furnace using a nickel-based brazing filler metal.

We have heard that the overlap for other types of brazing is supposed to be 3T-6T, where T is the thickness of the thinner member being joined. Should we use the same overlap for our aluminum joints?
