[MW:28829] As per B31.3 2012 & Section IX

Dear All,

Welding Process -GTAW+SMAW

PQR Thickens is 25.4mm

And Material is A106 Gr.B My query is as below -

1) For Sour Service what are the test we required and what is the minimum and maximum thickness qualification for WPS.

a) What is the Base metal thickness Range and Deposited weld metal range as per B31.3 for GTAW & B31.4 for SMAW.

b) As Per ARAMCO & Sec IX- AWS No(Class) ER 70S-2 / 3 can we use in WPS . but in PQR they have used only ER70S-6

Please looking your favorable reply on my query with standards.

Thanks and Regards

Kiran

Greetings,

First of clear whether you want to make buttering on machined parts or weld joints or any damaged parts?

Buttering: read QW-283 fully and 283.3.

Weld repair or build up: check QW-202.3.

Usually company standards specifies, Buttering or weld build-up on the prepared surfaces shall not exceed the lesser of ⅓ of the base metal thickness or 10 mm, if exceeds you need company approval, this is just request upon certain owner requirements.

Thanks.

Re: [MW:28826] Aws D1.1

Sorry guys for late reply.

Thanks to all.

One more question.

As per Aws D1.1

If we have a pqr with FCAW-GS (machine)

Can we make the wps using this machine Pqr to FCAW-GS (semi-auto) and vise versa?

Best Regards,

Chandra

Hi Chandra,
1- Yes, he is qualified for fillet welds on pipes regardless of the pipe diameter. Table4.10 - Check note " f " for joint shapes.
2- Shielding gas is not an essential variable for the welders. Changing the composition of the gas is an essential variable for FCAW-G for prequalified WPS and for PQR as well. Check table 3.1 & 4.5

Hi all,
I have few questions regarding AWS D1.1.

1. If a welder qualifies on 3G and 4F
He is qualified for all positions on fillet welds.

Is he qualify on pipe fillet weld? What Diameter limits he can weld on fillet.

2. If a welder qualifies the welding process FCAW using mix gas (80%Ar +20%CO2)
Can he weld FCAW process using 100% CO2?

Please suggest ...

[MW:28823] Use of ss309 electrode in cracked area

Dear experts

Whether it is advisable to use ss309 electrode to arrest the crack in mild steel material .As my job is fully machined it is difficult to completely remove the crack.kindly guide me.

Re: [MW:28822] Material certification EN 3.1 OR 3.2 ?

From your screen shot clause, we can predict it will be Type 3.2 certification only as per EN10204.

Since these activities involved more Financial matters, These clarifications / confirmations might be obtained from client during bidding or TQ stage itself.

Sometime client may accept 3.1 certificate itself when material is supplied by reputed VENDORs. ( Check the Approved VENDOR list by client )

unless if it is critical components like reactors, LNG storage tanks, etc..

Thanks and Regards

Re: [MW:28821] WPS welding process dipostion

Hi Kumar

Your doubt "how we decide filler metal diposition" i understand that , why used 13mm gtaw and 27mm smaw ? instead of other possibilities - right ?

There is no restriction in ASME Sec-9, You can deposit any thickness you want and range qualified shall be as per table QW-451.1

Means in single test coupon, you can use multiple process and range qualified on your each process is based on WM thickness deposited.

This is the role of welding engineer to decide and prepare WPS/PQR to cover your current job and future job thickness requirements

i suggest to read QW-200 thoroughly

Thanks and Regards

Dear sir,

I needed advice, along with Reference code for EIL specs Jobs.

a) I received plate from X mill, While verifying MTC it has been observed that 1 tensile test has been provided, While code requirements of 2 tensile test.

How we can proceed for MTC approval with check test? ( either 1 additional test of Tensile or 2 tensile )

B) I received plate from X mill, While verifying MTC it has been observed that for 310S, content of MO missing in MTC as per code has requirement of MO .

How we can validate to proceed for MTC approval with check test ?( either 1 chemical content of MO / full content chemical analysis / Both tensile Chemical)

Please Advice.

Thanks & Regards

Re: [MW:28816] WPS welding process dipostion

Pl share minimum info like PQR thickness, deposited Weld Metal thickness for each process in order to respond to your doubt.

What your WPS shows is the Base metal thickness range qualified, NOT individual process WM thickness range.

Thanks and Regards

See if wps showing separately as per what has been written for each process in wps and the same applies you should follow the same.

If the case your pqr has been qualified as per qw-452.1(b) and you want to go beyond that then you should rewrite your wps accordingly if your pqr qualifications for smaw has been recorded with 3 layers over with 13mm.

Read also qw-200.4.

Thanks.

Re: [MW:28815] WPS welding process dipostion

See if wps showing separately as per what has been written for each process in wps and the same applies you should follow the same.

If the case your pqr has been qualified as per qw-452.1(b) and you want to go beyond that then you should rewrite your wps accordingly if your pqr qualifications for smaw has been recorded with 3 layers over with 13mm.
