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

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.
