Are staybolts always welded in?

Generally no. The flexible staybolts are driven-over with an air hammer on the inside of the firebox (the round head of the flexible staybolts must be able to move slightly in their respective sockets on the outside, and then there is a cap screwed or welded over the sockets). Ridged staybolts are also driven-over on both the inside and outside. Sometimes they are seal-welded, but generally not when newly installed.
