[MW:35140] comment recive dfrom client

Dear Sir

i have recived a comment from my customer on PQR submitted as our PQR/WPS code edition 2015 is PQR dated 07.02.2019 what is the format or document to show it was used in last year ,we are using same since last 5 year.

 "'It is not allowed to use PQR issued five years before their application for the equipment construction unless VENDOR can demonstrate that the relevant WPS has been used during the last 5 years. The WPQR shall contain a document, which assure the welder activity shall be according to adopted Code"".

Kindly let me know what reply, and pls send me format of  Weld plan, weld map and test plan

Regards

asif Mulla

[MW:35142] Buttering

Hi, 

I hope you are all very well.

I wanted to know the reason behind why we use inconnect and E309L electrodes for buttering? what is the reason behind using those? Suppose a dissimilar weld between low alloy and carbon steel. We do buttering of inconnel on Low alloy metal.

Re: [MW:35143] Buttering

Let us know the production weld condition to respond to your query 

The query can not be answered in isolation 

Is PWHT is applicable ? 

If yes PWHT Parameters?

"Equipment service conditions?

Re: [MW:35144] Buttering

Yes, PWHT is a requirement for Low alloy but not for Carbon steel. PWHT requirement for Low alloy is "heat upto 630-660 deg C and hold for 1hr and cool down to 400 deg C in controlled way and cooling to ambient should be done under insulation

Re: [MW:35148] Buttering

PL correct if I am wrong 

Er309 L is wrongly written .

It is CS TO LAS joint 

Then 309L is not a compatible consumable .

You can chose either E7018 or E 8018 B2 ( LAS if Gr 11 type)

Here you can butter E7018 - 1  on GR 11 edge 

Do PWHT 

Prepare bevel 

Then do DPT/MPT

Then weld the CS with E7018 /E7018-1

RT as a NDE

[MW:35136] Radiography marking as per ASME Sec. VIII Div. 1

Dears,

Vessel joint efficiency is 0.85

Vessel RT requirement is Spot. 

Dished end having weld seam and fully RTd as the joint efficiency of head is 1 and other parts satisfied as per UW-52 spot RT requirements. So what would be the marking on name plate, RT3 or RT 4 or RT2.

Thanks in advance.

The interpass temperature when welding ASTM A572 Gr 50 with electrode E11018M (ENiCrMo-3) depends on the specific welding procedure and project requirements. However, here are some general guidelines:

- The interpass temperature for welding ASTM A572 Gr 50 typically ranges from 150°F to 300°F (65°C to 150°C).

- For electrode E11018M, the recommended interpass temperature is usually between 200°F to 250°F (90°C to 120°C).

- It's essential to consult the welding procedure specification (WPS) and the electrode manufacturer's recommendations for specific interpass temperature limits.

- Maintaining the appropriate interpass temperature helps prevent weld defects, ensures proper weld penetration, and achieves the desired mechanical properties.

Remember to always consult the relevant welding codes, standards, and project specifications for the specific interpass temperature requirements.

   So, for the material maximum inter pass temp 315 degree as per API 582, we need to mention 120 degree in the WPS right as per your table which is low

Sir,

The interpass temperature for welding ASTM A572 Gr 50 typically ranges from 150°F to 300°F (65°C to 150°C).

where you get this limits sir?

Reply i got From AI is below 

The interpass temperature when welding ASTM A572 Gr 50 with electrode E11018M (ENiCrMo-3) depends on the specific welding procedure and project requirements. However, here are some general guidelines:

- The interpass temperature for welding ASTM A572 Gr 50 typically ranges from 150°F to 300°F (65°C to 150°C).

- For electrode E11018M, the recommended interpass temperature is usually between 200°F to 250°F (90°C to 120°C).

- It's essential to consult the welding procedure specification (WPS) and the electrode manufacturer's recommendations for specific interpass temperature limits.

- Maintaining the appropriate interpass temperature helps prevent weld defects, ensures proper weld penetration, and achieves the desired mechanical properties.

Remember to always consult the relevant welding codes, standards, and project specifications for the specific interpass temperature requirements.

[MW:35133] Fwd: Hardness test requirements ( Nos. of reading requirement in pipe weld)

Dear Group members,

I have a query regarding hardness testing in pipe weld size 2" to 30".

Have any procedure or code standards for taking nos of reading for hardness test on Pipe weld like diff sizes..

Like 2"-to 6"

8"- to 14"

16"- to 30".

Re: [MW:35134] Fwd: Hardness test requirements ( Nos. of reading requirement in pipe weld)

Dear Lalit,

Based on client specification

Hardness tests on a production weld shall include a reading on the centre of the weld and the heat affected zones on both sides of the weld. The hardness test of the heart affected
zone shall be made at a point as near to the edge of the weld as practicable.

Each test area three impacts shall be carried out and the average of these shall be recorded. All results and averages shall be recorded on the Hardness Test InspectionReport.

Butt welds on pipes of nominal size upto and including DN100 (4") one set of
readings shall be taken on the 12 o' clock position or 6 o' clock position

Butt welds on pipes of nominal size from DN150 (6") to DN300 (12"), two sets of
readings shall be taken 120° apart, with one set on the 12 o' clock position & o' clock
position

Branch connections and fillet welds on pipes of all diameters, two sets of
readings 180° apart shall be taken.

Note: location shall be approved by CONTRACTOR/COMPANY prior inspection

Best Regards

V.Kingsly Geo.
