My concern is that as per given Data sheet there is not specified Tensile Strength ,on what basis we can accept Report of Tensile Test?

This is my first experience with unlisted material.

[MW:31375] RE: 31371] PWHT Thickness Requirements.

Hi ,

Which version of B31.3 code you're following , 2018 or older?. You may still avoid PWHT, if the design code is of 2018 edition. See the exemption clauses from B31.3 -2018 as highlighted.

Note: If PWHT is mandated by design or process condition, e.g. sour service or other conditions, PWHT is mandatory irrespective of thickness. The  designer has to specify that in the drawing.

All appropriate clauses are highlighted for better understanding. Hope this would help you.

 

Thanks.

Dear all

 

Pls what is the current thickness requirements for PWHT as per ASME B31.3? 

 

I came across old version of the code, it specifies that PWHT not required for all P1 materials, provided min preheat is maintained at 95deg'C.

 

We intend welding; 18" sch 80(23.83mm) to ASTM A 106, 24" sch 80(30.8mm), is PWHT required? Cite relevant Code sections Please.

Re: [MW:31369] Supplementary Essential Variables

This clause is applicable when Notch toughness tesing is specified.

Please Refer  ASME Sec IX clause No. 251.2- Essential variables are those in which a change, as described in the specific

variables, is considered to affect the mechanical proper�ties of the weldment, and shall require requalification of the WPS.

Supplementary essential variables are required for me�tals for which other Sections specify toughness tests and are in addition to the essential variables for each welding

process.

Please check the MDMT / PMS /piping class / data sheet, then decide the notch toughness requirement.

Note: PSL2 is notch toughness tested material and confirm with the mill test certificate.

RE: [MW:31363] RE: 31360] Re: As per ASME Sec IX Ed. 2019, ASME Sec VIII, Div-1 and API RP 582

Hello,

You would almost certainly have to go Charpy impact  test for 32.88mm thickness and MDMT 5 Centigrade.

It is per UCS 66 (a) ASME Section VIII, Div. 1. Combining thickness, temperature and materials (SA 516 Gr 60 / SA 516 Gr.70), you would be slightly below curve B of Fig. UCS 66 M.

This, for the WPS with this combination of base materials.

 

Anyway, recheck the final thickness. And compare with the data given by the Curve.

 

It is also possible that my assessment is wrong. It's a matter of reading what the experts have already told you.

Hi KK,

 

What's the design  code ? ASME Sec VIII , DIV-1 or ASME B-31.3. Looking at the text below, it sounds  Sec VIII, DIV-1 is the design code.

Look at this curve and the exemption clauses for more clarifications. If this curve exempts BM/thickness from impact test , then weld/HAZ should be exempted from impact also.

 

Thanks.

Hi KK,

 

What's the design  code ? ASME Sec VIII , DIV-1 or ASME B-31.3. Looking at the text below, it sounds  Sec VIII, DIV-1 is the design code.

Look at this curve and the exemption clauses for more clarifications. If this curve exempts BM/thickness from impact test , then weld/HAZ should be exempted from impact also.

 

Thanks.

 Dear Experts,  

  
Can I get a response from you?

 

According to  ASME Sec.8, and MDMT is 5°C.

 

Please send me your valuable reply to my doubts.

Dear Experts,  

 

Impact testing requirements for  Equipment Anchor Chair to top plate/wash welding, base plate, and plug welding.

According to ASME B31.3  above 25mm impact test required.

So for that,  I have restricted to my thickness range 5.00mm to 25.4 mm in WPS.

But Now my requirements for welding Equipment Anchor Chair to top plate/wash welding, base plate, and plug welding.  up to  32.88 mm,

For the 32.88 mm thickness, I have to conduct an impact test or not required impact test 

Process - SMAW.

P No - P1.Gr.No- 1 to P1 Gr,1/2

Thickness range - 5.00 mm to 32.88 mm.

Material - ASTM 516 Gr.60 to ASTM Gr.70

 

As per ASME Sec IX Ed. 2019, ASME Sec VIII, Div-1, and API RP 582according to mentioned code required Impact test or not?

 

Thanks in advance

Re: [MW:31359] Suitability for wps

3G will qualify all position with impact, could you pl give code ref. 2G & 3G will qualify only F<H<V

Hi Sandeep,

Thanks for the information, so if I would make one more PQR in the 2g position and do the mechanical test it would qualify for all position. Is there any Claude in aws d1.1 which mentions this? It would be very helpful for me.

Thanks and regards

Chris

Dear Chris,

There are 2 Options.

1) You can Weld an additional Test Coupon with  3G Position using qualified  3G WPS parameters. Then You can Carryout  onlyImpact Test as per Material Requirement/ Project Requirements. If Impact test results found satisfactory, WPS will be qualified for all Positions.

OR

2_You Can develop a New WPS for 2G Position which will qualifies Flat & Horizontal.

With Regards,

Sandeep.P.Raghavan

hi you should develop new wps for 2g because horizontal position 3G vertical position.

Hi friends

I have made a wps in 3g as per AWS d1.1 , I was under the impression that if I qualify in 3g it will automatically be qualified for flat and horizontal.But it seems there is a code restriction for this and I can weld only 3g for production welds.
My doubt is if i make one more test coupon in 2g for the same wps and get it qualified will it work??
Or should I need to create a new wps jus for this 2g position ??

Thanks in advance
