DEFINITION

Classification: 219/85.1

Brazing or soldering:

(under subclass 50) Subject matter in which the metal is heated and filler metal is used to produce a weld by means of brazing or soldering.

(1) Note. The filler metal (flux or solder) is to be applied to at least one surface of the metals to be joined.

(2) Note. This subclass and the subclasses indented hereunder were formerly unofficial digests. Hence, the placement of documents therein might not reflect schedule hierarchy.

SEE OR SEARCH THIS CLASS, SUBCLASS:

129, for brazing or soldering where an electric arc (torch)

provides the required heat.

615, and 616, for specific means of applying the heat.

SEE OR SEARCH CLASS 29, Metal Working, for generic brazing and soldering means and methods.
