.~.~.~> Flux affixed to or incorporated with filler
DEFINITION
Classification: 228/223
(under subclass 214) Process including application of a substance to the meeting faces of the work or the filler to promote union of the meeting faces.
(1) Note. The flux substance of this subclass may protect the work from oxidation, may clean, or may catalytically enter into the reaction between the materials being united, during the bonding operation.
SEE OR SEARCH THIS CLASS, SUBCLASS:
207, for bonding with the application of flux wherein the flux is active prior to the bonding operation to modify a condition of the work or filler. By comparison, the process of this subclass serves to modify a condition of the work or filler during or after the bonding operation.
218, for the application of fluxing material in the form of a gas or vapor, which establishes a protective or reactive atmosphere about the vicinity of the bond.
SEE OR SEARCH CLASS 148, Metal Treatment,
23+, for a fluxing composition or method of fluxing using a particular fluxing composition, even when that method is designated to be a method of soldering, brazing, welding, or fusion bonding.
