nstress,
Please do not forget to use SS 309 ( high nicel content)electrodes for welding, to prevent welding zone from ferritic and/or martenize type of stainless steel formation ( instead of austenic- I assume vessel is austenic stainless steel)

I made some presuure vessels from cladded steel. Base metal was 20-30 mm P355GH and clad was 3 mm 316L. The bevelling is to be V shape. The welding must begin from clad steel with 316L filling material. But at the welding of the transition zone ( CS and SS ), the filling material must be high...
