Re: [MW:14042] Heat input value in WPS

By Materials & Welding
Dear Nilesh,
Please see attached some literature on the subject. In short, you are required to work within the PQR established heat input values. No more, no less. I know in Shell DEP, there is some reference to it, but this literature explains it better. Hope it helps.
Best regards,
Shashank Vagal

Thank u TG
 Can u give the detail example so that i can understood more.

Hi Nilesh,
'matter of fact the lower range value is equally important. If the heat input is reduced as compared to PQR values, tendency to harden increases as cooling rate is increased. In your WPS, you need to mention the range as recorded in the PQR.

Hi Nilesh,

 

Being impact as a requirement, you will have to limit the maximum Heat Input value in WPS as qualified in the PQR. You will have to indicate the values on WPS with upper limit restricted to that in PQR.

 

Thanking you,

Rgds,

Subject: [MW:13977] Heat input value in WPS

 

Dear Experts,

I have question we are doing WPS, PQR & WPQ ( Material- IS 2062 GR B & thickness- 20 mm ) as per EN 15614 standard in which impact is essential.

So which value of heat input is to be mention on  WPS.

 

With Regards,

Nilesh

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

By Materials & Welding
Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

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...
