im with you on that one. Hence my post above. I have never seen inconel rod used on anything but inconel. Im not a boilermaker, but I work with several of them. Arn't most if not all boiler tubes carbon steel? No reason to use inconel rod. A short 7018 boiler rod is what I have always heard they use.
Im with the both of you..

you have been nothing but a ***** through the whole thread. Im glad that you have welded stainless to non stainless material, but you wont even look for the guy to see what to use? im glad you think you can weld being in a fab shop, why dont you get out there in the real world of welding and weld something 4 inches of the floor in a corner with a mirror and see how those fab shop skills do for you.

I have used 309 or Cronatron 333 countless times to join mild to stainless. I have never had any issues. I have used these same rods to weld different types of tool steel together. Incidentally these were used in metal stamping dies at 1000+ tons of force.

Inconel is used for dissimilar metal joining alot, but it is costly. 309 is a much cheaper alternative, and is used mostly to attain an acceptable ferrite number in the diluted weld metal. Other rods could be used, yes, but as mentioned, alot of the boilers are joined using 309 and do fine. I have seen a few switch to Inconel or nickel-based fillers though.
