My kingdom for a class i could take on welding... the stars never align for me.

Certainly not that I am adverse to learning, but I just can't 'handle' classroom atmospheres of any type.

Probably something to do with my being a high school dropout...

So why TIG for naval nuclear pipe? Because it is slower and more precise? Something in the TIG process that makes it better?

So, how do you wel a 4" thick piece of pipe? Just layers upon layers? How long does this process take?
The 3-1/2" wall thickness I welded on was 32" O.D.,low pressure side of a turbine in a power house.
One pass of TIG(consumable insert) and(3/32-5/16") 9018 LH out.Four welders on 12 hour shifts and if I remember right about 3 days.X-Ray at the start of each shift.
Passes could be no wider than twice the rod size.Lots and lots of passes.Pre-heated also.

I just don't have the patience.

Last time I did any stainless steel Mig welding was in the 1970s. We used a tri mix gas. Far as penetration, I really don't know. If doing pretty much flat welding you can get into spray arc transfer welding.

I understand SA has about 3 weeks maybe experience now so take his words with a grain of salt. :D
