DEFINITION

Classification: 228/256

(under subclass 101) Process which includes contacting the meeting faces with molten filler or distributing molten filler to the meeting faces.

(1) Note. Included herein is soldering, brazing or welding in which contact of fused filler with the meeting faces of the metal parts is effected by scraping, scratching, brushing or other surface exposure with some instrumentality while the surfaces are in contact with the fused filler. Aluminum is soldered or brazed by this process.

(2) Note. This subclass includes joining parts together while subjecting molten filler to vibration to distribute the filler.

(3) Note. Included herein is a process in which the meeting faces are moved relatively to one another while there is molten filler between them so to better distribute the filler throughout the joint.

(4) Note. This subclass includes immersing the assembled meeting faces in a bath of molten filler to effect fusion bonding as well as immersing a single meeting face in a bath of molten filler followed by bringing that face with its still liquid coating of filler to a corresponding meeting face to effect securing by fusion bonding.

SEE OR SEARCH THIS CLASS, SUBCLASS: 204, for a process using porous or capillary feed material on or between the meeting faces to facilitate distribution of the filler throughout the joint.

212, for application of a resilient clamping pressure to urge the parts together which, as an incident thereto, causes flow of filler from between the meeting faces as the filler metal fuses.
