Braze terminology question
Braze terminology question
(OP)
Fillet is the term for the braze alloy structure formed in a fillet joint or fillet weld. Is there a term for the braze alloy in a butt braze? Butt?
Thanks,

In a fillet braze the braze material forms a joining structure called a fillet.
In a butt joint the joining material forms a structure called a ?

In a joint where there is a step or angle at the interstions of the two parts being joined, the miniscus of the filler metal will solidify to form a fillet. The fillet is not actually inside the joint.
In a butt joint, the filler metal will solidify into a shape with no special name, and is just refered to as "the filler metal."

Background: the application is brazing carbide to saw blades. I was teaching about the importance of adding fillets to what is essentially a butt joint. One person said that he thought the material between the steel body and the carbide tip was the fillet since fillet means something flat. I told him he was correct about the definition of fillet meaning flat but in brazing (which is governed by the AWS) fillet referred the shoulders of the joint. He said “O.K. then what is the braze alloy between the carbide and the steel called?”.
Since the best joint in this application is a combination of butt and fillet I would like two separate terms to describe the two separate sections of the braze alloy.
E.G. the fillet should be roughly a right triangle. The distance on the flow onto the steel plate should be roughly the same as the distance of the flow on the exposed carbide which creates the side clearance on the saw blade. There should be some wetting onto the plate to indicate plate cleanliness. The braze alloy between the steel and the carbide (called ?) should be about 0.003” to 0.005” thick.
