Dear sir,

ER70s-6 available in TIG rod form also. But as you said, a new qualification is required. 

Thanks & best regards

Dear Mr Noble,

ER 70S-6 in MIG welding consumable and ER 70S-2 is TIG consumable, hence both are different process and new qualification is required.

Dear Experts,

If a PQR is qualified using ER70S-2 with impact testing, can we use the same PQR to prepare a WPS using ER70S-6, since both filler metals fall under the same F-Number and A-Number?

Would this be acceptable under ASME Section IX, or would a new PQR be required?

Your expert opinions and code references would be appreciated.
