RE: [MW:6181] Welder Qualification-Thickness range

By Materials & Welding
1 thing need to be carefully considered during the preparation of welder pqr that "MAXIMUM TO BE WELDED" is limited with the WPS which you are qualified to. This means that even if you have welded a test coupon with a thikcness of more than 13 mm your qualification range in thickness will not be a MAXIMUM TO BE WELDED but will be a maximum figure shown on your WPS.
 
best regards,

It is meaning that any thicknesses below 13 mm will be qualified to 2t for example if a welder made weld with 6mm then its thickness qualification will be 12mm
But any thicknesses equal to 13mm or above with minimum three layers, the qualification will be maximum to be welded for example if a welder made weld with thickness of 13mm then its qualification will be unlimited but the weld must be with minimum three layers

Can you explain in detail regarding in SEC IX - QW452.2?
Welder thickness range for unlimited thickness?we are confused?With
example please?

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...
