Dear Ganesh,

Job PQR thickness - 25.4mm                                 

Process - GTAW (4mm)+ SMAW(21.4)

as per ASME sec IX, Qualifications range for GTAW 4mm --- min - 5mm, max- that is <19mm, 2t =8mm      ----------------  GTAW - MAX  2t - 8 MM

Qualifications range for SMAW 21.4mm -- min-5mm, max- that is >19mm, 2T=2(25.4)=50.8mm                   ----------------  SMAW - Unlimited Thickness if PQR has been done with 3 layers of welding.

So..

The total thickness welded is 25.4(4+21.4)mm

Total thickness qualified is -=8+50.8=58.8mm                                                                                                ---------------   GTAW - 8 MM MAX  & SMAW  Unlimited thickness

Gent's

Can any one explain with example of thickness qualifications - procedure.

Especially for combination of process with 19mm to 38mm thickness job welded. 

Explain me each and every step. 

Here I explain what I am understand that code. Weather it's wrong please explain.

Example. 

Job PQR thickness - 25.4mm

Process - GTAW (4mm)+ SMAW(21.4)

as per ASME sec IX, Qualifications range for GTAW 4mm --- min - 5mm, max- that is <19mm, 2t =8mm

Qualifications range for SMAW 21.4mm -- min-5mm, max- that is >19mm, 2T=2(25.4)=50.8mm

So..

The total thickness welded is 25.4(4+21.4)mm

Total thickness qualified is -=8+50.8=58.8mm

Is that correct or not.

If it wrong kindly give me a brief lesson to me.

Thank you

Ganesh
