Gentlemen, Is PWHT can be avoided if the welded head (2 piece construction) performs normalizing after forming ? Head MOC : SA516 Gr 70, 45 mm thk, fabricated by welding the blank in two pieces.  Complete vessel not required PWHT.

Dear all, What is the Fully killed process & Normalized Rolled. In Plate MTC Remarks given is HSM2 PROCESS ROUTE: BOF-LHF-RHOB-CC-HSM2  what is this pls describe me  Thanks & Regards Ranjeet Bagchi -- 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.

For ASME IX, in general, I am aware that a groove weld during WQT will qualify for all thicknesses for actual production's fillet weld. However, is there a  minimum required thickness  for this groove weld during WQT? We used a 5 mm plate for WQT groove weld, Single-V, GTAW + SMAW. GTAW by other welder/before WQT; The GTAW pass was about 4mm and the SMAW (excluding capping/reinforcement) was just 1 mm. Does this 1 mm pass qualify us to weld ALL thicknesses for fillet weld during production for the SMAW process? During production, the joints are all T-Joint fillet weld using SMAW process. -- 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.

For the "FORM QW-483 SUGGESTED FORMAT FOR PROCEDURE QUALIFICATION RECORDS PQR", I've had a disagreement with our client / owners during the WPS/PQR review. Towards the end of the suggested format where it says "Tests Conducted by ____ _XXXXXXXXXXXX_ _____"; are we supposed to fill in the name of (1) PIC/QC Engineer/Main Overseer of the PQR from the 'Organization' company (the one who decided on the test coupon size, thickness, electrode, current, amp, WPS, etc. (often our/Organization QC Manager or Senior QC Engineer); OR (2) the Person who conducted the Mechanical Testing (Bend, Tensile, macro, hardness, etc.). For (2), the Testing is often done by multiple technicians from 1 testing laboratory, or a different laboratory for NDT (if conducted),or different laboratory for special test (outside the ASME IX testing requirements). So, there often isn't a specific singular person for all the NDT and Destructive testing. What is supposed to be filled ther...

Dear Experts       We have wps it's mentioned filler wire E71T-1CJ, but in the market available only E71T-1C. What is the difference between two filler wire and can we use E71T-1C instead of 1CJ Thanks & Best Regards Saleem manhappulath Mob:+966533595849 WhatsApp:+919526445936 From iPhone xs -- 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 David,  There are two points in WQT. 1. Thickness of Base Metal -T 2. Thickness of Weld Metal -t When you use a combination of two processes or two welders then they are qualified with reference to the deposited weld metal. If the first welder deposits 4mm Thickness, then you will measure the thickness of Root and hot pass, and for the other welder you will measure the remaining thickness of base metal to be welded plus the thickness of Reinforcement (Caping).

If dish normalised no need to do PWHT.
