Re: [MW:12933] Preparation of WPS and PQR for GTAW and SMAW

Dear Gupta,

1. One WPS with combinatipn of 2 PQR also allowed. If u have 1PQR for GTAW & 2PQR for SMAW separately.

2. Recomended to use MIN 38mm plate since above thk 38mm required PWHT.

3. Filler ER70S-6 - GTAW / SMAW E7018/E7016

4. Material can be SA517 GR70 or any P1 group material. (If no impact test, if yes Group no is essential), either plate or pipe will do @ thk 38mm.

5. Pre-heat 10 deg c for t >32mm (aslo can refer ASME Sec 8 div 1) at non mandotary appendix R.

Regards,

KavinM

Dear Mr. Gupta,

1) Only one WPS/PQR can qualify your range.

2) You can qualify the same using a 20 - 22 mm Plate coupon.

3) Filler to be used - ER 70S2 & E 7018 for SMAW.

4) You can qualify with Single -V Butt Joint.

Dear All

I have to make a WPS and PQR for Pipe ASTM 106 Gr. B (P no. 1and Gr.
no.1) and Dishend SA 516 Gr. 70 (P no. 1 but Gr. no.2) both 40mm thk &
24" dia using GTAW Root and Hot Pass then SMAW for the remaining
passes as per Sec. IX of ASME.

Kindly give your input on below points.....
1) Is it possible to make only one WPS for the above processes?
2) What should be the joint design for both and also SA 516 Gr. 70 is
not available in pipe?
3) What should be the recommended filler rod and Electrode to be used?
4) What thickness of pipe to be used to qualify the above WPS so it
can for the production weld?
5) What should be the preheat temp and Interpass temp?

If you have any sample WPS and PQR for this then Pl do forward it to
me.

Looking forward for your reply.

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

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

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...
