require to join 4130 rod into a 18-8 fitting. Basic strength requirement - like to avoid cracking.
Any comments & / or suggestions for filler rod. Looking at TIG process. Not a critical application - short term / corrosion susceptibility not a factor here..

ER309 or Nickel base alloy if PWHT is required.
