I often make adjustable brackets and other stuff out of split clamp
shaft collars, which are usually 12L14. And while I've never had a
weld break, you can sometimes see what appear to be small cracks in
the weld, especially near the ends of a bead. I usually TIG with 308SS
So while 12L14 is not generally considered weldable, I'd say you can
usually get away with it for non-critical, lightly stressed joints.
