MIG is no doubt the most user-friendly welding method of the lot. Very

I always found acetylene was..but then I was trained on that - not on
arc of any sort.

But you can't beat stick for heavy plate IMO; assuming you have a proper
oil-cooled job like an Olympia or Oxford and not some Chinese "inverter-

I doubt then you've ever done any car body repairs. All too easy to warp
panels with acetylene. Very difficult to do that with MIG - unless a total
idiot.

I'm surprised. I think it's universally acknowledged that oxy-acetylene
welding requires considerably more skill and practice than any other
commonly used method (doubly or triply so when working with aluminium!)

Really? It has one huge advantage., You can see the torch and the
workpiece with a mask on BEFORE you start welding.

Yes, I've welded aluminoium. And soldered it, too.

MIG/MAG is usually much easier for thinner stuff. TIG will do really

MAG??

Most wire fed gas shield welding on steel uses CO2 as a primary
shielding gas rather than pure Argon or Helium. CO2 is classed as an
"Active" rather than an "Inert" gas, hence MAG rather than MIG.

Trouble with TIG is the work piece has to be *super-clean* for some
reason, so it's a drag to prepare.

Yup, the more refined the process, the cleaner it needs to be usually.
If you want to weld through a load of rust and crap, there is not much
to beat stick!


That said, I once watched a really exceptional welder repairing a
fractured cast iron cooker pan support with TIG, and when he'd finished
not only could you barely detect the repair, the grey "stove enamel"
which I guess was actually a glaze seemed to have flowed back over the
metal.

Back in the old days when young research officers had no money, one of
our lab techs used to get all our cheap rusty cars through the MOT in
the evenings, and he only used gas. Never saw him having a problem with
warping. But we only employed techs with amazing skills. Looking back,
I'm not sure how our HR and management did the recruitment so well, I
guess they researched the references and had good contacts.

How much welded body repairs was he welding with a gas axe though?

You can do that with stick, MIG or TIG welding, with a auto-darkening

Quite a difference between doing structural repairs just to get through an
MOT and restoring an old car properly.

But then MIG (or rather affordable ones) didn't exist in the old days.

Well, I didn't worry about "pretty" in those days, he mainly did the
structural stuff required for MOT which was typically floors, sills,
chassis rails, suspension mounting points etc. But sometimes fitting
wings as well. I guess these were stiff enough not to distort, and minor
warping of floor panels isn't really visible.

Basically they are that parochial. They have always been
