Re: [MW:28826] Aws D1.1

By Materials & Welding
Sorry guys for late reply.
Thanks to all.

One more question.
As per Aws D1.1

If we have a pqr with FCAW-GS (machine)
Can we make the wps using this machine Pqr to FCAW-GS (semi-auto) and vise versa?

Best Regards,
Chandra

Hi Chandra,
1- Yes, he is qualified for fillet welds on pipes regardless of the pipe diameter. Table4.10 - Check note " f " for joint shapes.
2- Shielding gas is not an essential variable for the welders. Changing the composition of the gas is an essential variable for FCAW-G for prequalified WPS and for PQR as well. Check table 3.1 & 4.5

Hi all,
I have few questions regarding AWS D1.1.

1. If a welder qualifies on 3G and 4F
He is qualified for all positions on fillet welds.

Is he qualify on pipe fillet weld? What  Diameter limits he can weld on fillet.

2. If a welder qualifies the welding process FCAW using mix gas (80%Ar +20%CO2)
Can he weld FCAW process using 100% CO2?

Please suggest ...


Best Regards,
Chandra

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...
