I read in sci.electronics.design that Viktor Mikhailovich Polesov

It's not steel at all, let alone stainless. It's silicon-iron (no
carbon, so not steel). You don't need to weld it, and if you did you
would melt the secondary insulation. Also, you would need to find the
right technique for welding it: a special method and a special filler
rod are required, otherwise you will damage its magnetic properties. All
you need to do is clamp the parts together. If you have a milling
machine and a welding shop, I'm sure you can make up a clamp from sheet
steel and a few bolts.
