I totaly agree. As long as you ensure safety is not compromised, you can "get away" with a lot of things are aren't technicaly
correct.
I have MIG welded numerous stainless exhausts with standard mild steel wire, and wilst the welds always go rusty, they seem to be plenty strong
enough. Then again, as you say "Stainless" dosen't really mean anything without the grade.

Well, Mr.Trident, I've never sent a u2u to you, as far as I recall. I have one forum persona, and I have the necessary intestinal fortitude to
stand by my statements.
From everything that you, and one or two others have said, cast iron cannot be welded either, nor joined to other metals.
As a last resort, there's not many metals that can't be joined by brazing. Which in some places is also called gas welding.
Alongside my car work, I also get involved in shipping and yachts. I see Ni-Cr steels being welded to mild steel far too often to question it, on
ships as well as yachts. Yesterday I was involved in brazing bronze and monel together. I suppose that can't be done either.
People are always trying to tell others what can't be done. Wake up, and start working out what can be done, and how to do it.
Where's Mr. Allanson when his welding experience and knowledge are needed?
Go into your local welding shop and learn something new.
Cheers,
Syd. 
When you start calling people names, then the argument is lost, on your part anyway.

Syd,
It seems that for most of my early career I have been doing it wrong - the crucibles at Hincley Point must now be reinspected as they must be falling
apart, several ships in the merchant navy must have sunk by now, an oil rig in the same boat!
If a pressure vessel was made of stainless and mild, with an EN8 interlace and welded up with a hobby gasless MIG then I would agree iot would cause
problems.
What I suggested was a 6oz dog bowl being welded to a ms pressed axle case. The only stresses on this item would be its own weight and the lateral
weight of the pint of oil within - lets keep things in perspective!!
The whole thread has lapsed into a 'who knows most but has done least' competition, lets keep it practical, or rename the site
'Spaceshuttlebuilders.co.uk'

If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation
