Hello Thank you for your answers. the pwht was made with electrical resistances and blankets of insulation to all the header (About 4 m length). Is almost imposible to say that the problem was HIC, because we preheat to 200 C, we made pwht asap the last weld was cold and the electrodes were...

Hello Please, I need your help and I thank you in advance. We Weld several tubes 42,4x4,5 SA213-T23 to header 219,1x30 SA335-P22. We preheat to 200 ºC. We weld with GTAW process and filler metal ER90S-B3. PWHT was made 1,5 hours to 750 ºC. The joint was the tube straigth beveled and the...

Then I´ll make preheat at 200 ºC and PWHT at 735 ºC 1 hour. Is that well in your opinion?

Hello I have to weld tube-tube diameter 42.4 and thickness 4.5 mm quality SA213-T23. I suppose that I need to Preheat > 150ºC. Do I need to make PWHT, what holding Temperature? what time? I found searching in the web some papers. Any of them specified PWHT 740 ºC 2 hours, another specified...

Thanks for your answer. Then if I weld the tube to the pipe in Fillet weld (without penetration in the tube) with throat < 13 mm. in according with note of ASME I PW 39 can I avoid the PWHT

Hello. I am going to weld a tube of diameter 60.3 and thickness 6.3 mm. at a pipe of diameter 400 mm. and thickness 40 mm. The tubes are of quality grade T22 (2.25%Cr and 1%Mo). It´s material number P5A. Is it necesary Post welding heat treatment treatment in according with ASME I PW39? I...

Mr168, metengr, Thank you very much for your answers. My PQR is with Preheat 150 ºC and without PWHT. Probably i´ll make a new PQR without Preheat and with PWHT 700º 30 minutes. This way I´ll be in according with ASME I code? And what about the sound engineering for this welds? Is it...

Hello I must build 2 coils for a superheater for a Boiler. The coils will be manufactured with tube Ø51 x 5.6 mm quality 10CrMo9-10 (=SA213-T22) welded to fin of plate ?5 mm. quality SA387-Gr22. Every fin will be welded both sides with process GMAW with solid wire Ø1.2 mm. ER90S-B3. The...
