Hi,
AD2000 HP2/1 Table 1 defines the max. bending randius for the welding procedure test coupons as follows, but i could not find the definition of the "a"

Thanks metengr,
When we cut the pipe in to two halves we get 4 weld surfaces, but 2 faces were the same in practical as they mirror images of others. When i say 40 macros i was thinking like cutting each pipe in to quarters to get different sections of the weld. Is my thinking wrong? I hope i'm...
Hi,
I have questions about the Tube To Tubesheet welds. BPVC Sec. VIII Div.1 UHX not specifies the qualification method so i may use either of groove weld, fillet weld PQR's or Mock-up.(Sec. IX QW-193)
My first question is, which one will you prefer for the attached weld detail? As far as i...
Hi,
UG-84(h)(3) Material Over 11/2 in. (38 mm) Thick. When procedure tests are made on material over 11/2 in. (38 mm) in thickness, three sets of impact specimens are required. Heat affected zone specimens shall be as described in(g)(2) above. Two sets of impact specimens shall be removed from...

Hi everyone,
Is there any ISO / EN standard or document specific for overlay welder qualification.
If not, any method other than ASME BPVC Sect. IX
Thanks,
Hi,
I have an other issue. Our client, asked for additional hardness test as per QW-453 note-7. Question is where hardness measurements should be made. Figure 462.5(e) is not clear about hardness (in my opinion : ) )
Should hardness measurement made on conditioned(prepared/machined) weld...
I am about to try to qualify a weld overlay procedure to ASME section 9.
Question is, base material has elongation over %20(~25) and the overlay weld metal has below %20 (~15). In this case what will be the bending jig dimensions according to QW-466? Which elongation have to be used to determine...
Hi,
What is the definition of the "Heterogeneous Butt Joint"? I search through the net and find many definitions but none of them clear.
We are welding Armor plates(quenched and tempered, high strength) with austenitic filler(undermatching) and transverse bend tests fails. Because armor plate...
I'm working for a company which provides industrial inspection and testing services. We have EN ISO/IEC 17020 & 17025 accredidation and a working QM system. We are not manufacturing any products.
I have few question about Q1 certification program.
Does a service provider like my company get Q1...
Why range is 10 to 20? this part is not clear for me. Table says nothing about minimum weld deposit thk. unlike QW-451.1
if test coupon weld deposit thk. is t than max. weld deposit thk. is 2t. It is clear but no info about minimum thk.
if test coupon weld deposit is t>13 than there is no...
I looked trough the table and i think it is a bit confusing. One column lists actual weld deposit thk. other lists the range as maximum thk. I think there is no minimum. Any other toughts or maybe offical interpretation
Is there a minimum thickness limit for qualified weld metal thickness (groove weld, ASME BPVC Sec IX)
let's say welder tested from 10 mm thk plate. What is the qualification range for welder
10mm to 20mm or 0mm to 20 mm
thanks in advance
Impact testing not required in my case.
A senior eng. told me if a material not listed in Section 2 tables it cannot be used to qualify WPQR. S235JR not listed Section II D tables.
But i could not find any code reference supporting his argument. Does his argument valid?
Hi Everyone,
Is it possible use a PQR(prepared acc. to Sec IX) with EN material S235JR (which is listed in Sec IX table QW/QB422 as P1 material) for manufacturing stamped Sec I Boiler or Sec VIII vessel from P1 material (eg SA516)
Is there any restriction etc.
