[MW:3358] Re: Heat Input

By Materials & Welding
E6010 will support up to -29 degree celcius only and used in pipe line root application. But if the PQR passes the impact you can use it with batch restriction.

E 7018-1 is acceptable up to -46 degree but selection E 6010 is not suitable for LTCS ! As per which clause it is selected for LTCS ?

Adi,
Heat input is a guideline for subsequent welding. The yardstick is the average  value as obtained from your PQR. Your production welding should not exceed PQR HI values.
By the way, is 6010, 7018-1 Ok for LTCS?  What is the working temp?

I have done the PQR for LTCS by using 6010 & 7018-1 as per ASME SEC IX
some time i got 5KJ heat in put
What is the limitation for heat input and where it is mention?

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...
