RE: [MW:11514] Welder's approval as per JIS but WPS is as per SEC IX

Read QW-423.1 and QW-423.2.

In part QW-423.1 reads: ". . . When a base metal shown in the left
column is used for welder qualification the welder is qualified to weld
all combinations of base metals shown in the right column, including
unassigned metals of similar chemical composition to these metals."

And QW-423.2 reads: "Metals used for welder qualification conforming to
national or international standards or specifications may be consider as
having the same P-number as an assigned metal provided it meets the
mechanical and chemical requirements of the assigned metal. The base
metal specification and corresponding P-number shall be recorded on the
qualification record."

Therefore, for the purpose of welder qualification, provided the JIS
material can meet the stated requirements for equivalency, then the
welder can be considered qualified per ASME Section IX.

Dear Dave,
As you asked, according to my view if a WPS is qualified as per ASME
Section-IX. Welder will be acceptable on JIS specification. But it
must be check that in every case it follows the same or not.

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...
