MONEL 400 to SS304 Welding
MONEL 400 to SS304 Welding
(OP)
We need to weld a 1/2" Monel-400 piping with a 1/2" SS-304 Valve.
Can some one suggest proper filler wire or a WPS to carry out this Butt weld joint.
Service temperature is 35 Deg C. & service pressure is 300 kg/cm.2

While using Inconel 182, will its higher iron content cause dilution problem in weld pool?
I mean SS 304 and Monel has diffrence of Fe content!
Please comment.

I think you are confusing the iron dilution problem when using E/ERNiCu-7 alloy weld filler metal when diluted with iron from the 304 ss.

I did not confuse rather wished to clarify as there is a difference of Fe contents in SS304 and Monel 400.

Hot cracking is a very real possibility when welding with Monel welding filler metal. Even when welding with appropriate Nickel base filler metals or Nickel filler metals. hot cracking in the Monel HAZ can be a problem due to the large liquidus to solidus temperature range of Monel (even when properly cleaned).
Cracking in the HAZ of Monel castings is a greater possibility. Depending on the melting practice used for the Monel casting it may prove unweldable.
