Awaiting swift response from experts

I am developing PQR for piping.Impact test is required per B31.3.cupon (A333 Gr 6 to A350 LF2)thickness is 32 mm and will be welded by GTAW(8mm)+SMAW(8mm)+SAW(16mm). Do I need to carry HAZ impact for each process. If yes, where i will find reference of this in code.For weld I know each impact...

Thanks weldstan.will the consumables be same for A694 F70 welding also?

Can anybody suggest welding consumables for GTAW, SMAW & SAW process for welding of A694 F65 to itself and A694 F70 to itself.thickness is 32 mm and PWHT is required per B31.3 code. Service is SOUR so Ni% in weld consumables is required below 1%. Please suggest??

I have one open enquiry where in a spool design and fabrication is required as per ASME B31.8 Customer piping class has flange MOC as A694 F65 for forging and size is 36"x 1500#.This size & rating is out of scope of B16.5....so we r using sec VIII Div I code to design these special flange...

No, you can draw single sample which includes each process.you can include sketch of drawn sample in report to show each process weld/HAZ is included.

are you proposing 150 deg c preheat only? fillet weld throat is 12.7 mm.....does it need PWHT per B 31.3? i will qualify first butt weld cupon per QW 451 of sec IX

I have to weld C45 material with A106 Gr B pipe.Design code is B31.3.since no P number assign to C45 per sec IX,my existing P1 to P1 qualification will not suffice. C45 material is 50 mm thick and will be welded to 12.7 thick A106GRB pipe by fillet weld. I am chosing E7018-1 electrode for...

A350 LF2 CL1 material requires impact test , so not sure you can use the above WPS to weld A350 LF2 material as WPS is qualified without impact test

I have a 1.5" sch 160 (7.16 mm) pipe to Flange weld joint, external re-reinforcement is 1.5 mm & inter weld protrusion is flush with ID. Customer specification is asking to use EN 462-1 wire type IQT with 2% minimum sensitivity.However RT is to be done as per ASME sec V. I tried X-Ray with...

Customer is asking us to provide 3.2 certificate for Inconel filler wire which is 0.8 mm in diameter.currently it is only 3.1 certified and customer is willing to accept it under upgradation from reputed TPI. Do i need to weld a test cupon with above inconel filler wire or simply send the wires...

I reviewed Scope of NORSOK M650 which does not calls out NORSOK certification for austenitic stainless steel. However our customer is insisting us to have F316 Forging from NORSOK approved supplier. Customer spec is generic for A182 which states that norsok certificate (if applicable), I...

We have a PQR qualified per ASME sec IX with additional test to meet PED requirements in 2009.The test and PQR are approved by Reputed Notified Body from UK.Unfortunately the notified body number is not stamped on PQR document. Is it mandetory to have N.B.number on PQR document? we will be using...

Thanks DekDee for your response. Can you elaborate little further on this. If I understand correctly , for B31.3 welding with notch toughness requirement , my base material limit will be T/2 to T+6 mm & that of for Sec VIII Div I it will be T to 2T or T/2 to 2T. off course I am referencing this...

In ASME Sec IX -Ed 2013 Table QW-451.4, I can see that general note added as "supplementary essential variables apply when notch toughness is required by other sections" Does this mean that base material thickness for fillet weld shall be as per QW 403.6 when toughness test is required?

Thanks metengr Has anybody came across SA516 gr 60/65 plates which are without ferrite/ pearlite banding and also passing in HIC test. I am having hard time to locate it, specially 16 to 22 mm thickness.

Thanks weldstan

As per A672 specification, weld deposit shall match WPS chemistry. Does this mean that chemical composition of weld metal of 672 shall match "A" of its applicable WPS which is chemical composition. For example for A672 C70 CL 12 pipe, weld chemistry matching to A number 1 Is my above...

We did recover the straightness by using inside jacks with cold work.now the straightness of pipe around nozzle weld is within 3 mm.it seems customer will accept this repair. Thanks everybody !!!
