It is more about maintaining fleet numbers than increasing them of we talk about retrofitting old ships.
As for new stuff, keep in mind that they are building new shipyards in addition to expanding existing ones.

Mind you special welding but I couldn't resist

Welding in inert gas, Argon. There was recently some documentary on Borei subs that featured few minutes of video regarding welding in argon.

Titanium welding.
They manufactured the whole Alpha submaines in those suits.

Not only titanium, many alloys are welded like that, magnesium, some aluminium alloys...
Also they welded Alpha subs in sections with argon being poured onto weld so to say. It would be mindblowingly expensive to weld major sized sections in chambers.

The alpha/sierra submarines are mindblowingly expensive.
It is cheaper to flood the whole building with argon than to blow contentiously argon onto the hull.

Doubtful its cheaper, where is that building now, because i never saw such module in any Russian shipyard. Place like that would be very famous in engineering circles.
Small parts and sections are welded in complete argon atmosphere, rest are 99,99% of the time welded with "conventional" protective gas layer formed on the weld itself. But sure, if you can show me 100m long welding chamber i am open minded.

Looks like Russia might be serious about getting some Aircraft Carriers.
