1) None of the filler metal specifications you listed have a Hydrogen designation. If I were required to use low hydrogen wire I would make sure the hydrogen designation was clearly noted on the label.
2) Impact designation "J" = 20ft-lbs @-40 deg. C, assume this is for low temperature applications?
3) What is "Low temperature carbon steel material?"
4) Looks as though you desire to use Ar/CO2? (M designation)
5) You (or the EOR) will have to determine yourself if a usability designation of either 9 or 12 is appropriate for your project.
6) Buy a copy of the specification you are inquiring about.
Hi khodabandeh
As mentioned in another post, if the client spec wants the welding consumable to be considered "low hydrogen", then it is best to purchase the FCAW consumable with a "hydrogen designator". As this is optional in most of the FCAW specs, you will have to clearly specify this when purchasing the filler. Generally H4 (4ml/100g weld metal) is considdered very low hydrogen, although the client spec may be kind and specify that H8 (8ml/100g weld metal) is OK.
The material spec to which you are purchasing your FCAW filler will give the details for testing. For instance, ASME II C SFA 5.29 deals with the low alloy FCAW electrodes, and Table 9 in that spec gives the hydrogen designators.
Hope this helps.
