NBIC/ASME Code Question
NBIC/ASME Code Question
(OP)
When a Contractor that holds an "R" stamp and normally preforms their own welding, subcontracts out the welding (due to their customer requesting a process that they have no Procedure for or knowledge of, how is it handled from a code stand point?
This is a repair of a Routine Nature per the National Board Inspection Code being done on a Power Boiler within the State Of Wisconsin.
Under Whose Code Stamp is the work preformed?
Who is responsiable for the documentation, paper work and or Reports?
Any input on this subject would be appreciated.
Thanks,
Weldor

RE: NBIC/ASME Code Question
The responsibility relies on you as the manufacturer. The only thing that you are doing is hiring sub-contract welders and if I am interpreting this right the welding must be qualified on your paper. We just finished a job with the same problem and all documentation was still completed by us. Also the stamping was completed by us. And, have you submitted this to your AI? How does he/she feel about this? In short the ultimate responsibility is up to you. Hope this helps.
RE: NBIC/ASME Code Question
The subcontractor as an independent entity must have his/her own qualified weld procedure. You in turn must approve that process. I.e. the subcontractor prepares the WPS, conducts the PQR testing, and qualifies the welder. Your responsibility is to review and approve his process and supporting documents meet the code requirements as well as your own.
RE: NBIC/ASME Code Question
Perhaps I wasen't clear in my question, I am the Customer of the contractor that has hired the sub-contractor and I would like to know what Reports, Documentation and or paper work should accompany the R-1 report and who should sumit the report for the sub-contractor that the first contractor has hired.
I hope that this makes things a little more clear.
Thanks,

RE: NBIC/ASME Code Question
Sorry on my misinterpertation of the question being asked, the documentation is to be completed by the R stamp holder making the repairs/alterations. I am under the impretion that you are the owner, which means that you are responsible in signing and accepting the documentation. You can find these requirements in the 2001 NBIC code under RC-1000 through RC-1094. Hope this helps

RE: NBIC/ASME Code Question
I understand that and from what his previous post is it is unclear exactly what position he is in. I agree with you 100%that is why I referenced back into the code that much, if I am not mistaken RC-1070 references the Inspector's roles,RC-1094 references the Documentation. I believe after further reading these 2 paragraphs I am positive that he will know exactly what his role will be in this alteration/repair. Thanks for the help
RE: NBIC/ASME Code Question
As I dig into this more I find that the work involves two "R" stamp holding contractors.
The first contractor employed the second contractor to do Orbital Welding of the tubes to save time.
Now for the potential Monkey Wrench, The Orbital welding contractor's procedure calls for a backing ring (no problem)
however the primary contractor fit and tacked the tubes that the orbital contractor welded.
My thinking on this is: We would need an "R-1" report from each contractor? (YES or NO)
The NBIC is vague on this.
The tack welding was preformed by the primary contractor under their "R" Stamp and the tacks were left in and welded over by the Orbital Welding Contractor.
RE: NBIC/ASME Code Question
I would say yes since both contractors put some sort of filler metal in the groove. I agree the code is very vague on this issue. Because if I am right the tacks were consumed in the Orital process. So I would get both contractors to fill out there R-1 reports describing their work. Hope this helps and good luck.
