Hi
I am glad you have discovered the backing for a torsionally flexible beam. A slit has been used before by manufacturers but has been lost to a google search engine.
My thoughts are that tackwelding it at intervals will just stiffen it proportional to the decreasing distance of the tacks and approaching the full stiffness as they approach full welding ? Why go there at all as minimal stiffness is desired ! The stress raisers of the tacks will cause problems in the long run.
Indeed my thoughts about it are really the details of the design and the welds will decide the stress points which in turn will determine the possibility of cracks. I would not use stainless tube.
