basically code says about pwht but heat treatment cycle is same as pwht and in pwht only weld seam is consider but is stress relieving only material is consider mainly name is different process is same but focus point is same ( weld joint in pwht and base metal in sr ). for fibre elongation u can go upto 40% for P1 material -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

Hi,  check ASME B 31.3  328.5 Welding Requirements for tack weld qualifications. 328.5.1 General (c)  Tack welds at the root of the joint shall be made with filler metal equivalent to that used in the root pass. Tack welds shall be made by a qualified welder or welding operator . Tack welds shall be fused with the root pass weld, except that those that have cracked shall be removed. Bridge tacks (above the weld) shall be removed. and check  QW-452.6 for  Fillet Qualification by Groove‐Weld Tests.

Hi Arun Some basic explanation as per my experience.   Like in pipe 6G position weld, you will have flat , vertical and overhead welding positions,   Like same way , for tubular connection joints, you will have connections like T joints, K joint & Y  joints in one situation, based on you profile, angles etc...( Branch connections )   If you look from bottom you will find T shape, side way look like K shape ( when two tubular joints occurs) and from top you will find Y shape. Hence it's called TKY joint.   It is most difficult welding in off shore modules. Since dihedral angle is less than 30 deg  and very difficult to pass root run welding.   Only 6GR qualified welders can weld and clear inspection requirements.   Clearing UT and Macro is very difficult unlike other joints.           Pl Refer AWS D1.1 – Section 9. Tubular St...

Dear dinesh, Its possible to do PQR  for SA516 Gr.70 plate with Hastalloy C276. I would suggest ENiCrMo14 filler with GTAW process. Probably it would be a Lap fillet welding so take a SA516 Gr.70 plate and hastalloy C276 sheet and make a production mock up PQR and then do Macro as per ASME Sec IX. It would qualify your purpose.
