Background: A welder tests on an NPS 6 Sch. 80 (0.432 in. wall) coupon, depositing 0.100 in. of E6010 and the balance of 0.332 in. using E7018. Question (1): Using E6010, is the welder qualified to deposit 0.864 in. maximum of weld metal? Reply (1): Yes. Question (2): Using E7018, is the welder qualified to deposit 0.664 in. maximum of weld metal? Reply (2): Yes. Question (3): Is the welder qualified to deposit 0.864 in. of weld metal using E6010 plus 0.664 in. of E7018 weld metal deposit thickness for a total of 1.528 in. in the same groove?

Jayesh I do agree with Prakash UTS will be affected on negative side hence your base material should have greater UTS during procurement. Further to that As you mentioned " so during cold forming vendor need one intermediate normalizing. and as per client requirement one more normalizing performed after complete dished end forming. So, total 2 time normalizing have to perform." It is interesting to understand 1.  what do you mean by "intermediate normalizing" ? 2.  When the dish is cold formed why is the vendor requiring normalizing.  Is your designer asking for same.  Can't both vendor and client requirements be satisfied in one normalizing Answer to your other questions is (1) During plate order i have to take 2 normalizing cycle simulation ? Yes Or No? With Reason You will have to test the sample to meet UCS 85 requirement after 2 cycles of normalizing (2) May I take benefit of Clause UCS-85 (i) of ASME sec-8 Div.1? You will have to test the sample to...

Hi We had faced this concern couple of times in our previous projects. Yes base material will lose strength when u apply such heat treatments. Best solution for this is to order plate directly from mill with end finish requirements (such as double normalising + SPWHT, if any).  If u aren't able to approach mills check for available plates having tensile on the higher side, test it with simulation of double normalising. If the results satisfactory then you may utilise the plates for forming.  Client requirements overrule the code requirements hence you have to comply and cannot take relaxation on it based on code. If the dished end manufacture wants to perform intermediate normalising then it cannot be considered as normalising after forming. Hence client requirement of normalising after forming requires to be performed separately.  If the dished end has long seam then ensure your PQR is qualified with double normalising or single normalising with aggregate time for both c...

Dear All, Pl note that, "SAND" is now prohibited in almost all around the world for blasting.  We shall not used this term.  "Blasting" is enough to understand and communicate.  Some answers I saw given " it depends on Painting scheme" but the question was regarding Blasting not painting.  For blasting RH shall be 60 or below.  Regards.

Dear Abraham, Thanks for the info, From your details its understood that, the subjected equipement two hydrotest is involved. In most cases only the Shop Hydrotest is a Inspection stage requirement for Authorized Inspector. Site Inspection stage will come under PID/OID. Based on the Shop hydrotest acceptance AI has cleared the MDR. On acceptance of the 2nd Hydrotest as per project requirement, he may review the report for Name Plate stamping. To make it clear, if possible directly contact Authorized Inspector to clear further.

Dear Ruban, Code of construction (like ASME Sec. VIII, I etc.) is tell us to qualified welding procedure as per ASME sec. IX. So please refer UW-28(c) of ASME Sec. VIII Div. 1. As I understand, fin is non pressure part & have no-load carrying function and it is performed with automatic welding process so procedure qualifications is not required as per code of construction. But still you want to check quality of fin to tube weld, you can refer international standards, which ask for pull out test and fusion width measurements test. Also you can refer various standard like GE, Dossan, EIL, IBR etc. for more testing requiment. During finning, please consider UCS-56 (tables), to waive off PWHT requirement. QW-263 is for resistance welding processes like spot, seam, projection weld.

2017 editions of ASME Section VIII-1 and Section VIII-2 has new requirements for the qualification of impact-tested weld procedures, found in ASME Section VIII-1, subparagraph UG-84(h)(5), and in ASME Section VIII-2, subparagraph 3.11.8.3(g), introduced restrictive requirements for the removal of impact test specimens when multiple weld processes are used. Code Case 2945 give some relief to fabricators to use previous qualified procedures provided (a) The welding procedure specification was qualified prior to January 1, 2018, and the procedure met the requirements of the Section VIII, Division 1 and Division 2, 2015 Edition. (b) The existing welding procedure specification may be used until the 2021 Edition of Section VIII, Division 1 and Division 2 go into effect on January 1, 2022. extension applies only to non-compliance with the specific new requirements that it mentions, and will not automatically apply to any other new requirements introduced in the 2019 editions o...

Hi, Your process is SMAW, which is QW-253, G no is Supplymentry essential variables and it becomes essential as per QW-403. (b) and (c) second paragraph clause. If G1 vs G1, you cannot use as per above as A 105 is G2, where as still if your A 106 falls under grade C  again this also falls under G2 (If A or B then G1) however A 105 is G2, hence irrelavant of impact or non impact G1 vs G2 combinations not ensured in WPS, so as per your approved WPS and as per above clauses, strictly you cannot use this current WPS for propsed material.
