A -G consumable does not meet any particular ASME/AWS SFA/A-5.x classification chemistry. This does not mean that it will not meet a Section IX A-Number chemistry range. You would need to evaluate the filler metal manufacturer's specified chemistry range to see if it fits one of the A-number chemistry ranges. Alternatively, you can specificy that the filler metal must meet a certain range. While not a G filler metal, I typically specify that ER70S-6 must meet the A-Number 1 chemistry requirements.

Subject: [MW:22396] G type consumable
Dear expert,
Is it true that all G type consumable example ER70S-G don't have A number under ASME?
This group only have F number? Is it true?
Kindly advice.
