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,

Your WPS will make as per ASME or API???

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.

Thanks and Regards

KK

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

Regards

KK
