Re: [MW:27944] ASME P1 Gr.2 PQR + WPS QUALIFICATION

By Materials & Welding
Here group no. falling in supplimentary essential variable.Client is asking to perform above PQRs. Our intention is to do one PQR and thus prepare above 3 WPS . Can We?

what you want to say on this. when there is impact requirement, group no is essential??

Dear Experts,

We are in requirement of PQR qualification for ASTM A106 Gr.B (ASME P1 G1)  with  ASTM A105  (ASME P1 G2) materials with notch toughness test as per ASME IX.

When PQR is qualified ,can we make following wps

P1G1 + P1G1
P1G1 + P1G2
P1G2 + P1G2   

If can, please advice which part of the code is agreeing with this.

Best Regards,
K M JIJILAL

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...
