[MW:28488] GTAW & FCAW - P92 Forging PQR Details

Dear Sirs ,

We are going to weld elbow to elbow of 16" Long Radius in production joint of material A182-F92, thk 60 mm, OD 406.4.

As we could not able to order the Pipe material for PQR urgently, we are going to machine forging material A182 - F92, which is to be machined to Min. 30 mm Thk and OD of approx 200 mm, for safer side.

I also checked about welding consumables, for GTAW - Metrode 9CrWV & FCAW - SuperCore F92 from Metrode, but could not find the parameters.

As this is the 1st time, we are going to run this type of material for PQR, can you share your valuable info about the AWS Class, Bevel Prep, correct Welding Parameters, Preheat & Post Heat, PWHT requirements to control hardness, other the ASME II C code info.

Thanks and Regards,

Saravanan Sornam,

Suwon, Korea

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

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

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...
