Re: [MW:34370] Which Filler wire to be used in between P43 (Inconel 625) to P8 (A240 310S) by GTAW)

By Materials & Welding


for dish head after cold forming heat treatment is not mandatory as per asme secVIII div1 untill you are not exempted from condition as per ug79,ucs79.
if not exempted than do heat treatment as per ucs56 called it stress relieving.

you have option of normalizing also for cold form dish head heat treatment but for that you need one copoun to be normalized and tested as per ug 85.

if dish head are welded than you need pqr with same heat tretament :-
if dish head is stress relieved- pqr also stress relieved
if dish head is normalized- pqr also normalized

Dear All,

Please help me with this:

1) which filler wire is to be used for GTAW welding of two dissimilar materials P number that is P43 (Inconel 625) to P8 (A240 310S).

2) For SA 516 Gr 70 22mm thick. Ellipsoidal 2:1 dish end, which heat treatment to be used as per ASME Sec VIII Div I UCS 56 After cold forming of dish end.

Please help me I this?

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...
