Re: [MW:30245] AWS D1.1 WPS qualification range for base material

1. Thickness Range for WPS without CVN testing: 3 mm to 14.22 mm

2. Thickness Range for WPS with CVN testing: 7.11 mm to 14.22 mm (Refer to Table 4.6 ( 2)).

Refer to Table 9.10.

I have to qualify a PQR in following conditions

Construction Code AWS D1.1
Material API 5L Gr B
Welding position 6GR
Base material
Diameter 6"
Thickness on none bevel end = 14.27 mm
Thickness on bevel end = 7.11 mm

Query

1. What should be the thickness Range for WPS without CVN testing ?

2. What should be the thickness Range for WPS with CVN testing ?

Looking forward for support with Clause reference if possible.

Re: [MW:30235] A335P11 material - Delayed PWHT condition

You can go for post heat if there is a minus temperature.

Dear Experts,

For one of our project,

With reference to the sketch shown below, we are going to weld 4 number of Single V Butt joints for A335P11 to itself ( P No. 4 ), pipe Thk of max 28.6 mm by using GTAW & FCAW process ,

Preheat Tempr. of Min. 120 Deg C ( Plan to use Burner ) and PWHT from 650 to 707 Deg C as per ASME B31.3 code.

After we complete the welding in our shop and bring back to the normal ambient tempr. around 15 Deg C, can we do PWHT after 1 or 2 days gap and then we do RT and PT ?

I worry that, during winter in Korea, the ambient tempr. may drop to Minus 10 Deg C.

As there is no weld spec from client for P No.4 , can we do PWHT after 2 days gap.

Please suggest me with any weld instructions for P. No.4 , Preheat maintenance, in order to avoid any crack after welding and with delayed PWHT condition.

With best regards,
Saravanan.Sornam,

Re: [MW:30229] A335P11 material - Delayed PWHT condition

Dear Mr.Kannayeram,

Thank you.

We are going to use GTAW & FCAW combination for it. After welding complete for the 6 Set. of A335 P11 Pipes as per the previously sent sketch, we are planning to do PWHT, either by local method or at Subcontractor's heat treatment area , all together in one time.

So, it may take Min. 1 day gap for PWHT preparation, after the completion of welding.

Also, if you have any spec for Preheat maintenance, its control and PWHT requirements for A335 P11 materials, then please send me a copy.

Regards,

Saravanan,

Re: [MW:30229] EPDM RUBBER SHEET VS BUTYL RUBBER SHEET

Butyl and EPDM are products of the good quality. They are very flexible, have high elongation and tensile strength which makes them both long lasting products.

Butyl is more flexible because it contains more than 50 percent butyl polymer. EPDM can work up to - 50 deg c while Butyl up to -60 deg C . Don't find any problem with EPDM.

Re: [MW:30225] A335P11 material - Delayed PWHT condition

Not only 48hrs and welding, NDE should be after SR because there is lot of chance for Reheat cracking

Dears,

thanks for the reply.

We are going to use GTAW & FCAW for P No. 11 materials up to 28 mm Thk, so can we bake for 300 to 350 Deg C for an Hr and bring back the Tempr. to 15 Deg C.

Can we do PWHT after 1 day Or to start PWHT immediately after baking .

RT will be taken after 48 Hrs of welding completion time.

If you have any weld spec for P11 materials, then please share me.

Dear Saravanan,
As per good engineering practices, 48 hours gap is suffecient time for P11material after PWHT as per your mail. More over, please consult your client if they have any specific recommendation.

Dear Experts,

For one of our project,

With reference to the sketch shown below, we are going to weld 4 number of Single V Butt joints for A335P11 to itself ( P No. 4 ), pipe Thk of max 28.6 mm by using GTAW & FCAW process ,

Preheat Tempr. of Min. 120 Deg C ( Plan to use Burner ) and PWHT from 650 to 707 Deg C as per ASME B31.3 code.

After we complete the welding in our shop and bring back to the normal ambient tempr. around 15 Deg C, can we do PWHT after 1 or 2 days gap and then we do RT and PT ?

I worry that, during winter in Korea, the ambient tempr. may drop to Minus 10 Deg C.

As there is no weld spec from client for P No.4 , can we do PWHT after 2 days gap.

Please suggest me with any weld instructions for P. No.4 , Preheat maintenance, in order to avoid any crack after welding and with delayed PWHT condition.

Re: [MW:30221] A335P11 material - Delayed PWHT condition

U can. Since it is bainatic structure, hardness level may not be as high as in Martensite structure. Why do you want delay in doing PWHT, if NDE is delayed, it is a reasonable one after PWHT because of delayed crack

Re: [MW:30221] A335P11 material - Delayed PWHT condition

Noted your query,there is no hard & fastened rule in the code for when to start PWHT after welding.In your case only pre heat & post heat is mentioned.Dont forget to maintain

Interpass temparatue for these P4/P11 matallurgies.

However to carryout RT or any NDTs in low ambent temperatures or lower service temperatures,it is preferably after 48hrs. of welding as per good engg. practice.

Check the project spec. for BSR-RT & ASR-RT and comply the same.Check the the hardness of weldments,HAZ and parent metal before & after PWHT.

Re: [MW:30217] A335P11 material - Delayed PWHT condition

Hi,

For welds made by SMAW and FCAW, after completion of welding and without allowing the weldment to cool below the minimum preheat temperature, the temperature of the weldment shall be raised to a temperature of ATLEAST TO MAXIMUM INTERPASS TEMPERATURE MAINTAINEDAS A MINIMUM OR 300-350 DEGREE CELSIUS for a minimum period of two hours. This hydrogen bake-out treatment may be omitted provided the electrode used is classified by the filler metal manufacturer with a diffusible-hydrogen designator of H4 (e.g., E7018-H4);

Dear

Where is written that after welding immediate do PWHT.

you can do PWHT after one, two or more days.

We r doing preheat during welding and after welding complete, we have continue preheat and come down temp upto ATM.

Re: [MW:30213] weld thickness

Please Refer QW-433 ASME Sec iX

1.If a welder qualified for F4 with backing can weld F3 with backing as per QW-433

Welder is already qualified for F3 without backing 0.200 inch max (2×0.100 inch) and One more 0.664 inch with F3 he can weld total 0.864 inch.

2. For thickness of weld metal qualified refer QW-452.1(b)

For example welder deposited F4 0.332 inch thickness weld metal deposited.

Maximum weld metal deposited will ne 2×0.332= 0.664.
