(under subclass 215) Process in which the confining means comprises either (1) a body of sufficiently high melting point or heat conductivity to establish, with respect to the fused filler contacting it, a cooled zone, or (2) a body which acts to retain the fused filler within the space between the meeting faces of the work part(s).

164, Metal Founding,
127, for a process of casting employing a "chill". Note that Class 164 takes molding apparatus and a process of molding
where the mold acts to contain and shape cast metal for producing a casting, whereas the body, or "chill", of this subclass acts to simply retain the filler within the joint; i.e., for all practical purposes the retainer of this subclass acts only as a back-up, the joining surfaces providing the other retaining surfaces.
