Dear  Ganesh, 
your undestanding was correct , go ahead.
 kindly ignore mail from Mr. V.Kingsly Geo. BCZ it is applicable for perfromace qualification.

Thanks

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

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

By Materials & Welding
Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
