Welding 304L to 321 SS
I had figured on using 347 welding rod to tig weld a tube spigot made of 304L to a 321 exhaust pipe. The tube is a condensate /rainwater drain.
A colleague of mine said Inco 82 would do a better job because of the higher nickel content.
I figure this is a situation where a little knowledge is dangerous. What are the pros and cons of using an inconel rod here?

In other words do you still need to corrosion resistance of SS?

The exhaust pipe is on a seaplane that is used in salt water, however the major concern is getting rid of rainwater collecting in the exhaust pipe, when the aircraft is moored.

I do have lead compounds present, residues from tetra ethyl lead.

I am familiar with Avesta products, I use their pickling paste.
All,
It is just as well I asked the question. I did not know about the cracking problems with 82 with lead in the picture. I will stick with my original choice 347.
This is what makes this forum work, no nonsense answers.
