Thank you Don.

This is really interesting. I have seen several “stitched” steam turbine casings around the world, with the classic 10” stitch added accross of the usual crack weld.
But nothing like this. I went to their website, and most of their pictures shows large marine engines, where removing the block is hardly an option, and so have the financial ressources to have such a repair technology developed.

The way you describe it is indeed what their drawings are showing.

This is something I will may be able to use in my work in the future... not on heavy industrial boilers, as it surely does not meet the appropriate section of the ASME code, but on gas engine generators.
