MTC appears acceptable; however, kindly confirm if end user specifications or applicable WPS/PQR require any supplementary tests such as impact toughness, intergranular corrosion (IGC), or hardness. All other parameters are in line with Sec II C requirement.

Yes, the WPS is okay for CS to SS fillet welding (P1 to P8) using ER309L, preferably by GTAW only since the thickness is less.

Dear Akhilesh ji,  WPS is OK but from next time, Do always mention the deposited weld metal thickness for each process.  Here, Fillet must be of atleast 6 mm (Plate is 6mm and Pipe is 5.54 mm) so Use GTAW only.  Thanks   On Wed, May 14, 2025 at 3:59 PM Akhilesh Kumar < akhileshlikes@gmail.com > wrote: Greetings Experts, I would like to bring your attention to and clarification about the below-mentioned materials required for welding in the structural platform for Instrument support.

So, i would like to confirm whether PWHT is mandatory as per UCS-56-4 ? Can we avoid PWHT for this 10mm weld joint ? Or Should we do buttering with ERNiCr-3 on P No.5A bevel and butt weld  with  same filler for this dissimilar joint to avoid PWHT after making new  PQR with buttering? Please confirm soon.
