[rajesh s. mhaske ,Engineer Welding ,PUNE,INDIA]

Dear sir
           Pipe dia : 323.*33 mm thk
           Tube dia : 50.8 *6.35 mm thk
           Groove design for  above pipe to tube welding  : set in (groove on header )  / set on (groove on tube  )
           Welding process : GTAW + FCAW

           Qualification of welder: OD >73 mm and Thk - Max to be welded with process GTAW+FCAW
          
Question :
            1) Can above qualified welder be deployed for welding of set in and set on joint.

   Dear sir

Now we are doing same but don't have document for reference

Dear Rajesh,

Hope this will help.

The following interpretation of ASME Section IX applies to Set-through and Set-on nozzle installation:
Interpretation: IX-80-67
Subject: Section IX, Nozzle to Shell Connections
Date Issued: December 8, 1980
File: BC-80-675
Question: When nozzle or branch connections are attached to the wall or head of a pressure vessel, what are the basic criteria establishing procedure and performance qualification requirements, assuming impact test is not a requirement?

Reply: Where the nozzle is attached to the vessel by welding completely through the thickness of the vessel wall, the procedure shall be qualified for the thickness of the vessel wall penetrated by the nozzle or attachment. Where additional metal is placed on either the interior or exterior of the vessel wall in the form of fillet welds, they shall be considered as having been qualified by the procedure qualification covering the thickness of the vessel wall. Performance qualification for this weldment may be made in plate to cover the appropriate thickness of the vessel wall and the position in which the weld is being made. Diameter is not a factor.

Where the nozzle or attachment is welded to the vessel wall by welding through the thickness of the nozzle or attachment, the procedure qualification shall be made for the thickness of the nozzle or attachment wall at the time of welding. Performance qualification for this condition shall be made with the appropriate diameter pipe as required by QW-452.3, with the range of thickness of weld metal qualified determined by the thickness of the nozzle or attachment wall at the time of welding. Any fillet welds, both procedure and performance, will have been qualified when qualifying for the full penetration welds involved.

Note: The above interpretation refers to nozzle attachment to vessels, however the criteria apply to branch attachments topressure piping as well.

Dear all
As per my my knowledge ASME dont classify set in and set out type .
If your welder is groove weld qualified with required parameters and u r having valid wps you can weld anything.
All above asked requirements are come from European codes.
Experts pls correct me if I m wrong
Cheers

Is the F no of the wires the same as in the qualifications?
If yes, he can.
Take care also of the other essential variables like current and polarity, innert backing for GTAW, short circuit thickness limitation, inner backing and transfer mode for FCAW

no, because dia of qualification is >73mm, but ur job calls for 50mm. ( I think u have qualified welders in Plate)

Update : QW-403.16 Subparagraph (a) and (b) added –

(a) For a groove weld attaching a set-on nozzle or branch (with the weld preparation on the nozzle or branch), the range qualified from Table QW-452.3 shall be based on the nozzle or branch pipe O.D.

(b) For a groove weld attaching a set-in nozzle or branch (with the weld preparation on the shell, head, or run pipe), the range qualified from Table QW-452.3 shall be based on the shell, head, or run pipe O.D.

Background – Revised to define welder qualification diameter limits for set-on and set-in nozzle or branch connections.
