Is there lead in the stainless steel kegs?

I have purchased two old stainless steel kegs for my homebrew.
Normally these kegs hold POP for restaurants and bars. I was told that
they periodically need to be recoated in a plastic coating to protect
against lead that is in the welds of the stainless steel.

Is this true or not?  Any advice

AFAIK, not true.  Lead welds in a pop keg?  No way.

agreed, aside from the harmful lead being a horrible idea to have around
sodas, the 25-50 PSI most corny keg systems run under to push syrup through
the tubing would blow a lead weld like a ford explorer blows firestone
tires.

How old are you talking about. I work for a beverage company and transfer
tanks that are still intact after 10 years is almost unheard of. They take a
great deal of abuse. To answer your question, tanks are welded, not
soldered. You should be fine. I know of no coating on transfer tanks.

I once had a hip-flask that was allegedly stainless steel, but which was
soldered together. I discovered that when I saw the seam was wearing
where the "weld" was exposed. I scraped at it with my pocket-knife, and
the material came up in a soft curl of metal that could likely be a
lead-based solder. I don't use that flask.
The odd thing is - good stainless steel does not solder well.
My flask (made in china and packaged with a bottle of Cutty Sark scotch)
may have been a poor grade of stainless, or just tinned steel.

Anyway, if your keg has any exposed seams, see if they're lead.

I have had a lot of experience soldering and I can tell you that Stainless
Steel is just about impossible to "Solder", Further, if a keg is used for
pressurized service, a standard 60/40 solder wouldn't hold against the
pressure (Same reason that A/C guys actually braze your copper pipes using
silver solder rather than the lead type) If I remember correctly a beer keg
has to be pressure tested at least to 300 psi ( may be wrong on that but
don't think so)

Good luck
