Dear All,
there is a correction in the clause.The clause is ASME BPV SECTION 1 PW 1.2 and PW 1.2.3
Is it possible for the vendor to use our qualified welders for repair welding? Authorised Inspector says no,he insisting vendor to bring their own welders.
I need expert advise in this issue.If anyone need further clarification,please feel free to ask.
Regards,
Limesh

Dear All,Thank you for your valuable inputs.Boiler manufacturer's supervisor is with us to co ordinate the repair work.But they don't have manpower over here to execute the repair.So they would like to hire our welders.But Authorised Inspector opposing that idea by quoting some clauses from ASME BPV Section -I PG 1.2 and PG 1.2.3. Can vendor use ourqualified welders in this situation?Anybody have an idea to get out from this trouble.We planned to cut the burner front wall tubes by keeping 500 mm in length at both header ends(top and bottom).Corrosion visible on the mid portion of the tubes.I think the refractory block is the villain in this case.Regards,Limesh

Limesh :
If your company certified as S stamp manufacturer you could take the job. Please check ASME Sec I Para 104.1
Anyway I wonder , are you absolutely sure that the corroded needs repair (or may be replace), since it is new one, what is the repair planned ? do you have suitable WPS/PQR for repair work ?
I suggest you to take the picture, take UT thickness check and ask the manufacturer/designer if this really needs to be repaired.

Subject: [MW:6330] Power boiler repair before start up
Dear All,
One of the boiler's burner front wall tubes found corroded.Boiler is
new one and not yet commissioned.Boiler assembled by us.Can I use my
company's or hired welders for a boiler repair constructed by other
company? ASME Authorised Inspector denied our request to utilise our
welders.AI advised us to bring the welders from the manufacturer side
for repair.Which code clause justifying his comment?
Regards,
Limesh
