Hi, I dont find where is the interpass temp.and all in QW403.6? Pls.Find below the Extraction from ASME Sec.IX-2007 QW-403.6 The minimum base metal thickness qualifiedis the thickness of the test coupon T or 5⁄8 in. (16 mm),whichever is less. However, where T is less than 1⁄4 in.(6 mm), the minimum thickness qualified is 1⁄2T. This limitationdoes not apply when a WPS is qualified with a PWHT above the upper transformation temperature or when an austenitic material is solution annealed after welding. Regarding Interpass Temp.Pls.find below the extraction from code. QW-406.8 An increase in the maximum interpass temperatureof more than 100°F (56°C) from that achieved on the test coupon and recorded on the PQR. The interpass temperature shall be measured and recorded separately for each tempering weld bead layer and, if any, for the surface weld bead layer(s). The WPS shall specify the maximum interpass temperature limits for each tempering bead layer separately and for the surfacing weld bead layer(s), if any. Hi limesh, As he pointed out for interpass temp.your wps shall be with interpass temp 140+56 =196 Thanks & Regards, (Karthik) Karthikeyan.S QA/QC Manager Getabec Energy Co.,Ltd. 379,Moo6,Soi8,Nikhomphatana, Rayong-21180, Thailand.
