[MW:34916] Applicability of Impact requirement as per ASME B31.3

Dear All,

Design code – ASME B31.3, Welding Code- ASME BPVC SEC IX

Material  to be used used during Fabrication - SA 333Gr6 (P No.1 Gr. 1) To SA 350-LF2 (P No.1 Gr. 2)

Production Thickness range-5.54mm(Minimum)-9.53mm(Maximum)

PWHT – Nil

MDMT-= -45 Deg Cel.

Kindly give your valuable suggestions for applicability of PQR impact requirement for above details.

Pl.reply with code clause.

Thanks & Regards

Re: [MW:34917] Applicability of Impact requirement as per ASME B31.3

Dear Vinit,

For the applicability of PQR impact requirements based on the provided details, we need to refer to the ASME Boiler and Pressure Vessel Code (BPVC) Section IX, which covers welding qualifications.

Since you're dealing with welding and materials in the context of ASME BPVC Section IX, the specific clause relevant to your scenario would be Clause QW-402.2. This clause outlines the impact test requirements for procedure qualification.

Based on the information provided:

1. Material: SA 333Gr6 (P No.1 Gr. 1) to SA 350-LF2 (P No.1 Gr. 2)
2. Thickness range: 5.54mm (Minimum) - 9.53mm (Maximum)
3. PWHT: Nil
4. MDMT: -45 Deg Cel.

Given these details, you would need to assess if impact testing is required for the welding procedure qualification. The decision would depend on factors such as the material specification, thickness, service conditions, and design requirements.

According to ASME BPVC Section IX, if the design temperature is equal to or colder than the Minimum Design Metal Temperature (MDMT) of the material, impact testing may be required. In your case, the MDMT is -45 Deg Cel., and since the design temperature is not mentioned, it's essential to evaluate whether it's equal to or colder than -45 Deg Cel.

Furthermore, Clause QW-403.6 provides exemptions from impact testing for certain materials, thicknesses, and service conditions. It's crucial to review this clause to see if any exemptions apply to your specific scenario.

Ultimately, the applicability of PQR impact requirements would depend on a detailed assessment of the specific welding procedure, material properties, thicknesses, and design conditions, in accordance with the ASME BPVC Section IX.

Regards,

Amol K.Betkar

Re: [MW:34913] Filler wire

E71T-1C  is Charpy Impact tested at -20degC

E71T-1CJ is Charpy impact tested at -40degC.

AWS Classification for FCAW is only a supplementary requirement applicable only when Impact test is required.

If charpy impact test is not required then you can use E71T-1C in place of E71T-1CJ

[MW:34870] ASME IX, groove weld during WQT limits for Fillet Weld production

For ASME IX, in general, I am aware that a groove weld during WQT will qualify for all thicknesses for actual production's fillet weld.
However, is there a minimum required thickness for this groove weld during WQT?

We used a 5 mm plate for WQT groove weld, Single-V, GTAW + SMAW. GTAW by other welder/before WQT; The GTAW pass was about 4mm and the SMAW (excluding capping/reinforcement) was just 1 mm. Does this 1 mm pass qualify us to weld ALL thicknesses for fillet weld during production for the SMAW process?

During production, the joints are all T-Joint fillet weld using SMAW process.

[MW:34870] FORM QW-483 SUGGESTED FORMAT - Tests Conducted by .........

For the "FORM QW-483 SUGGESTED FORMAT FOR PROCEDURE QUALIFICATION RECORDS PQR", I've had a disagreement with our client / owners during the WPS/PQR review.
Towards the end of the suggested format where it says "Tests Conducted by _____XXXXXXXXXXXX______"; are we supposed to fill in the name of
(1) PIC/QC Engineer/Main Overseer of the PQR from the 'Organization' company (the one who decided on the test coupon size, thickness, electrode, current, amp, WPS, etc. (often our/Organization QC Manager or Senior QC Engineer);
OR
(2) the Person who conducted the Mechanical Testing (Bend, Tensile, macro, hardness, etc.). For (2), the Testing is often done by multiple technicians from 1 testing laboratory, or a different laboratory for NDT (if conducted),or different laboratory for special test (outside the ASME IX testing requirements). So, there often isn't a specific singular person for all the NDT and Destructive testing.

What is supposed to be filled there?

Re: [MW:34874] ASME IX, groove weld during WQT limits for Fillet Weld production

Hi David, 

There are two points in WQT.

1. Thickness of Base Metal -T

2. Thickness of Weld Metal -t

When you use a combination of two processes or two welders then they are qualified with reference to the deposited weld metal. If the first welder deposits 4mm Thickness, then you will measure the thickness of Root and hot pass, and for the other welder you will measure the remaining thickness of base metal to be welded plus the thickness of Reinforcement (Caping).

Thanks & Best Regards,

Muhammad Asif

[MW:34878] Re: 14478] QW-403.6 OF ASME SEC. IX (MIN. THK. RANGE QUALIFICATION)

Dear all,

I have a question:

We currently have a Welding Procedure Specification (WPS) and Procedure Qualification Record (PQR) for welding a 25mm plate using a combination of Gas Tungsten Arc Welding (GTAW) and Shielded Metal Arc Welding (SMAW), with impact testing conducted. The weld metal deposited by GTAW is 5mm, and SMAW is 20mm.

Now, if I only intend to use the SMAW process for welding 8mm and 15mm thick plates, both requiring impact testing, would our existing WPS still qualify for this welding scenario?

On Thursday, June 7, 2012 at 5:19:11 PM UTC+3 John Henning wrote:

Minimum thickness is 6mm.

 

QW-403.6 says ". . . where T is less than 6mm, the minimum thickness qualified is 1/2T . . ." .   Since your thickness is not less than the general rule of T to 2T applies.

 

Note this wording has also given me heart burn.  What I have done is to take a 1/4 inch plate (nominally 6mm) and have the thickness machined to 0.249 inches, this then qualifies for thickness 0.124 to 0.499 inches.  If I need the thickness I will also weld a 1/2 inch thick plate to qualify 1/2 to 1 inch. 

 

Enjoy.

Re: [MW:34880] PWHT of Normalized head

Hi, 

If you heat treated 900°C , then no need to do 610°C.

Is PWHT can be avoided if the welded head (2 piece construction) performs normalizing after forming ?

Re: [MW:34881] Re: 14478] QW-403.6 OF ASME SEC. IX (MIN. THK. RANGE QUALIFICATION)

Your SMAW thick 20mm , lower limit is 16mm and higher limit 40mm. So your existing PQR not qualified.

Dear all,

I have a question:

We currently have a Welding Procedure Specification (WPS) and Procedure Qualification Record (PQR) for welding a 25mm plate using a combination of Gas Tungsten Arc Welding (GTAW) and Shielded Metal Arc Welding (SMAW), with impact testing conducted. The weld metal deposited by GTAW is 5mm, and SMAW is 20mm.

Now, if I only intend to use the SMAW process for welding 8mm and 15mm thick plates, both requiring impact testing, would our existing WPS still qualify for this welding scenario?

On Thursday, June 7, 2012 at 5:19:11 PM UTC+3 John Henning wrote:

Minimum thickness is 6mm.

 

QW-403.6 says ". . . where T is less than 6mm, the minimum thickness qualified is 1/2T . . ." .   Since your thickness is not less than the general rule of T to 2T applies.

 

Note this wording has also given me heart burn.  What I have done is to take a 1/4 inch plate (nominally 6mm) and have the thickness machined to 0.249 inches, this then qualifies for thickness 0.124 to 0.499 inches.  If I need the thickness I will also weld a 1/2 inch thick plate to qualify 1/2 to 1 inch. 

 

Enjoy.

Dear Experts,   What shall be the minm. qualified thk. range if PQR is qualified with 6 mm. Nom. thk. with Notch toughness properties. Will it be 3 mm. or 6 mm. as per QW-403.6 of ASME Sec. IX?   Further, suppose If I shall qualify this procedure on 5 mm. thk. PQR test coupon (machined from 6 mm. thk.), which thickness shall I have to consider for temperature reduction during subsize test specimen testing? Will it be 5 mm.(actual thk.) or 6 mm. (nom. thk.)?   Awaiting your experts' opinion at the earliest.   Thanks & regards,     C. R. GANDHI

Re: [MW:34882] PWHT of Normalized head

PWHT required specific holding time and controlled cooling as per sec VIII Div.1. Normalizing having air cooling after reaching at 900 deg c.  Since normalizing not required specified holding time and controlled cooling, will it substitute ?

Thanks & Regards

Re: [MW:34884] PWHT of Normalized head

Hi

Generally CS sa516 plates supplied in.NR condition i.e heating to above Ac3 about 900c and cooled in still air

As per ASME code Welded vessel above above 38mm nominal thk.req PWHT below Ac1as per UCS56 of course for sour /lethal service all the Vessels req PWHT irrespective of.nominal thk.
