There is no issue in using the proposed consumables.
Only restrict the Manganese content of GTAW wire below 1.6 % to achieve A No. 1 weld metal chemistry.
Thanking you,
Rgds,
Prashant

You can not use ER70S-6 for GTAW welding since it contains higher Si content than ER70S-2. ER70S-6 can be used if your shielding is by CO2 (i.e. in GMAW process). Purpose of addition of si is to flux o2 from weld when co2 is used as shielding.

One can choose to weld with a electrode classified for PWHT applications, for welding non-PWHT applications, this is not an essential variable, however for SAW process - it's same in this case
Hi Asad,
You can replace E7018 with E7018-1 but not ER70 S2 with ER70 S6 due to change in chemical composition (high Mn content).

Dear Asrad Azmi,
Additional to Mr. Arunachalam's comments
F7P8 EH12K (P= with PWHT) / essential variables as per QW404.9

Subject: Re: [MW:13913] use of E 7018 -1 & ER 70S-6 to weld SA 516 GR 70 MATERIAL
ER 70-S6 weld metal chemical analysis does not meet A No. 1.
If you have qualified a WPS with Er 70-S3 etc, then this wire is not acceptable. ( Manganese content is more than 1.6% in weld metal)

Dear All,
Vessel is being fabricated as per ASME SEC VIII DIV 1.
Base material - SA 516 GR 70 HIC - 30 mm Thk. IMPACT TEST not required.
normally we are using E 7018 for SMAW, ER 70S2 for GTAW & F7P8 EH12K for SAW Process to weld above base material.
Can we use E7018-1 for SMAW, ER 70 S6 for GTAW & F7P8 EH12K for SAW for the above base material.
Please Advice.
Thanks & Regards
Asad Azmi

Yes you can use ER70S-6. However, you will have to do a heat lot chemistry to verify that it meets the A1 chemistry limits. Such material is readily available in US and Europe. This requirement, “filler metal chemistry must meet A1 chemistry requirements”, should be added into your weld specification as a modifier/comment to the ER70S-6 classification.
Assuming the filler material meets the A1 chemistry and is therefore permitted, in my experience GTAW with ER70S-6 will give very good impact results particularly when PWHT is required (much better than ER70S-2 all other welding parameters the same). ER70S-6 is particularly useful when impacts are required and higher PWHT is required because Cr-Mo material is in the same fabrication and driving PWHT. In the latter case ER70S-2 generally fails impacts. Some of my data shown below:
PQR results w/ impact absorbed energy @ -20F (-29C) in ft-lbs
GTAW ER70S-6 (<A1) ER70S-2
T=t=1.5 in. (38mm) T=t=1.75 in. (44mm)
1150F (621C) PWHT 1250F (677C) PWHT 1150F (621C) PWHT
1/4T 1/2T
310 212 74.5 67
300 212 94.0 38
296 212 64.0 50
Enjoy.
