Yep "castellated" it probably is. But as non-native english speaker, I didn't want to try that out on a knowledgable audience :- 
I understand your wish to stay away from it. To execute that joint with the correct clearances would be a major undertaking in itself. Never mind making a boiler, we are going to make joints! And if you succeed in it, then covering it with lagging?
From what I read about it in "the books" it is more used on thicker plate like >3mm. Then you would have sufficient area for the solder.
But the use of a single wrapper and a formed plate between the wrapper and the barrel would be the best solution. It solves the issue of joints by having no joints. (better said by replacing it with a better type of joints)
