The easier way is to have a proper butt joint welded which would cover the set-up of your tube-to-tubesheet joint design and the applicable variables. Sometimes dissimilar base metal thickness qualification QW-202.4 may be applicable.

What is the Welding Procedure Qualification Record (PQR)?

Welding Procedure Qualification Records in ASME Code Section IX. The test specimen size and dimension must be based on identified values in ASME Code Section IX. After completion of welding and heat treatment (if needed), you need to send the test specimen to the metallurgical lab for mechanical testing.Welding Procedure Specification (WPS) Sheet 1 of 3qualification in any position qualifies the procedure for all positions. The welding process and electrodes must be suitable for all positions permitted by the WPS (ASME Section IX, QW-203). (For impact test application, there are some restrictions for welding in vertical-uphill progression position; See ASME Section IX, QW-405.2) Qualified Tube to Tubesheet Weld Procedure Qualification ASME Welded Heat Exchanger Tube or Tubesheet Joints 4.
