It's just not a matter of which side of the pond. It's US bicyclists Vs. everybody else. In the *American* Welding Society's brazing manual, the term Fillet Brazing does not exist. Brazing is, by definition, done with capillary action. If it ain't capillary, it ain't brazing.
So the Bilam sleeves would have been brazed on and then the tubes joined with a bronze weld.
In a lugless joint I; 1. Tack it in the jig/fixture. 2. Remove it from the fixture and *braze* it, flowing bronze into the interface between the tubes with capillary action. 3. Go around again and build a fillet using *bronze welding*.
BTW Cecil Behringer, who wrote several of the chapters, gave me my AWS brazing manual.
Using "weld" to denote a process there the parent metal isn't melted is confusing, even though it's "correct".
Perhaps "Bronze Filletted" would be both accurate and clear.
