Re: [MW:34913] Filler wire

E71T-1C  is Charpy Impact tested at -20degC

E71T-1CJ is Charpy impact tested at -40degC.

AWS Classification for FCAW is only a supplementary requirement applicable only when Impact test is required.

If charpy impact test is not required then you can use E71T-1C in place of E71T-1CJ

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

[MW:34869] PWHT of Normalized head

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.

Thanks & Regards

[MW:34870] ASME IX, groove weld during WQT limits for Fillet Weld production

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.

[MW:34870] FORM QW-483 SUGGESTED FORMAT - Tests Conducted by .........

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 there?

Re: [MW:34874] ASME IX, groove weld during WQT limits for Fillet Weld production

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).

Thanks & Best Regards,

Muhammad Asif
