Hi
Some basic information on this alloy is provided here. If the alloy is of Grade 1 type, meeting the nominal UTS with ER-NiCr-Mo3 filler and matching SMAW electrodes may be difficult. This would NOT be an issue if the alloy is changed to Type 2,(Solution Annealed ) variety. Pleas find the relevant information as attached.
At the first place, I would like to know, what’s the rationale behind choosing Type-1 alloy(Annealed) , strength/weight reduction?
Response would be appreciated.
Thanks.

Hi Balakriahnan,
I do have the same concern with Gr. 1 of UNS 6625 when welded with ERNiCrMo3 Kindly do reconfirm of grade again (Gr. 1 or Gr. 2) . Did you check if the filler manufacturer can retest the tensile properties and provide the as welded values? 785Mpa which is 95% of 827Mpa will suffice thd requirment. We do all weld tensile test for every batch we receive.
I hope the expert in this forum can guidw us to sort this out.

Dear Experts,
Greetings for the day!!
I want to quality PQR for Base material UNS N06625 GR1 which has tensile property 827Mpa, ERNiCrMo-3 Fillerwire was selected based on API582 & ASME sec II C recommendations. The filler wire tensile value is 760Mpa.
In PQR tensile test result lies in between 760-827 Mpa. The obtained tensile value is not greater than the base metal. It can't fulfill the requirement of QW-153 (ASME SEC IX).
As stated above clause QW153.1.c, " the applicable section".
Are there any provisions to qualify with lower strength than base metal?.
Reference WPSs were approved based on the tensile value being greater than filler metal tensile value (UTS) 760 Mpa MIN (sec II C), But there we could not get explanations from the originators.
Please also refer, ASME-B 31.3 clause 328.3.1 (welding materials) & ASME sec VIII div1 QW-06 (non-mandatory guidelines for welding material selection.
Thank you
Balakrishnan S

Hi Balakriahnan,
If the reduction in Tensile strength is not acceptable by your client, you may think about the option of switching to ERNiMo-19 type of welding consumable. Here’re some salient information, which you be worth considering. You’ve to keep the process conditions also in mind.
Thanks.

Dear Mr.P.Goswami.P.Eng, IWE.
We received the material of UNS N06625 Gr 1 (827 Mpa) only. As per the Welding consumable TC, the UTS is 772 Mpa which is higher than the requirement of ASME II C. The suitable consumable is ERNiCrMo-3 / ENiCrMo-3 as per API 582, ASME II C recommendations. But UTS of weldment lies less than 827Mpa. Some textbooks ( Welding Metallurgy and weldability of Nickel base alloys - John C Lippold) also explain that it can't be achieved. My query is any provisions in the applicable codes to allow lower base metal strength.
Thanks,
Balakrishnan S
