Need someone with 2006 D1.1 to look up something for me.

What is the dew point for shielding gasses for FCAW and GMAW? The older versions stated that it had to be a welding grade with a dew point of -40F or lower(D1.1:98 para 5.3.1.3)...I think it was revised, but I don't have my D1.1 with me.

John,
from D1.1 2006

Sent you something in your email

5.3.1.3 Shielding Gas. A gas or gas mixture used for
shielding shall conform to the requirements of AWS
A5.32, Specification for Welding Shielding Gases. When
requested by the Engineer, the Contractor or fabricator
shall furnish the gas manufacturer's certification that the
gas or gas mixture conforms to the dew point requirements
of AWS A5.32. When mixed at the welding site,
suitable meters shall be used for proportioning the gases.
Percentage of gases shall conform to the requirements of
the WPS.

C-5.3.1.3 Dew Point/Manufacturer's Certification
....Therefore, it is mandatory to have -40*F or lower dew point in shielding gas.
Shielding gas purchased as certified to AWS A5.32 meets this requirement.
