[MW:35599] Welding ASTM A312 UNS31254

Dear Expart,

Can you please guide on the steps to follow to weld UNS 31254 Pipe to Forging. We are facing much issue on weld finish and slag inclusion. We are using ERNiCrMo3 & ERNiCrMo3 consumables with 200 Deg.C backing and 70-80 Amp current. Please refer the attached photo of the welded joint. 

Thanks in advance,

This is small Pipe welding.

Pl use GTAW process full welding .

SMAW is not to be used .

Dear,

ERNiCrMo -3 backing temperature max 350 Deg.C. Can you try min backing temp 320 Deg. C and 2 hours must. For the welding consumables brand better go with Special Metals.

I would like to bring your attention to and clarification about the below-mentioned materials required for welding in the structural platform for Instrument support. In which required earthing clit/plate (6mm THK X 50mm H X 65mm W SS316)  to be welded with pipe (API 5L Gr B Thk- 5.54 MM) and channel (PFC 100x50x10mm THK). ASTM A 572 GR 50).

Could you please confirm that the mentioned piping WPS can be used for above mentioned ?

Thank you for your response and suggestion.

Re: [MW:35608] ASME SEC II PART C

MTC appears acceptable; however, kindly confirm if end user specifications or applicable WPS/PQR require any supplementary tests such as impact toughness, intergranular corrosion (IGC), or hardness. All other parameters are in line with Sec II C requirement.

Yes, the WPS is okay for CS to SS fillet welding (P1 to P8) using ER309L, preferably by GTAW only since the thickness is less.

Re: [MW:35611] DISSIMILAR WELDING IN STRUCTURAL

Dear Akhilesh ji, 

WPS is OK but from next time, Do always mention the deposited weld metal thickness for each process. 

Here, Fillet must be of atleast 6 mm (Plate is 6mm and Pipe is 5.54 mm) so Use GTAW only. 

Thanks

Re: [MW:35618] PWHT

According to B31.3

Table 331.1.1 PWHT

Table 331.1.3 Exemptions for mandatory PWHT

For nominal material thickness > 25mm not required PWHT if applied a preheat of 95 degree prior to welding.

For nominal material thickness > 5mm up to 25mm not PWHT required if applied multiple layer welds. (Single layer or single pass follow note 6 of table 331.1.3).

However, this depends by your WPS, if it is required by WPS you must be follow

Re: [MW:35619] PWHT

Dear Elavarsan 

As per B31.3

A preheat of 95°C (200°F) is applied prior to welding on any nominal material thickness >25 mm (>1.0 in.)

Multiple layer welds are used when the nominal material thickness >5 mm (>3 ∕ 16 in.) [Single-layer or single-pass welds may be exempted from PWHT, provided the WPS has been qualified using single - pass welds with ±10%heat input and that all other conditions for exemption are met.]

Depends on Your WPS

[MW:35620] As a QC Level 1, I'm wondering if I'm qualified to:

Dear Experts,

I hope this email finds you well. I'm reaching out for advice on a current project where we're performing flux core welding. We need to qualify our welders and ensure compliance with relevant standards.

As a QC Level 1, I'm wondering if I'm qualified to:

1. Evaluate and qualify welders?

2. Write Procedure Qualification Records (PQR)?

3. Develop Welding Procedure Specifications (WPS)?

4. Conduct Welder Qualification Tests (WQT)?

Specifically, we're working with flux core welding, and I'd appreciate guidance on the requirements and best practices for welder qualification and documentation.

Could you please provide advice or point me in the direction of relevant resources?

Thank you for your expertise and assistance.

Best regards,

DESMOND

If you are qualified as welding coordinating personal under ISO 14731 namely International welding engineer / technologist / specialist then you can carry out  the questions 1 to 4 as mentioned in your email and for which code of construction to fabricate and weld the component and certify welders .

[MW:35624] Can we avoid PWHT for P No.5A to P No.1 , 10mm weld joint ?

Dear Sirs ,

 

We have a project with both shell and Reinforcement Pad materials SA516-70, 10 mm Thk ( P No.1 ) and the Nozzle is SA335-P22, 4" Sch 120 , 

11.1 mm ( P No.5A ) Thk.

 We already have a qualified WPS & PQR with 8mm GTAW and tested about 10 years ago by other welding engineer, for P No,.5A to P No.1 without PWHT and it was satisfactorily passed and we 

have used that WPS & PQR for the previous project 10 years ago and no 

issues found without PWHT.

 Now for the new project, we are going to use the same WPS and apply 

Preheat ( 204 to 250 Deg C ) as per the WPS for 10mm Shell Thk by 

multipass welding, refer to the below sketches.

So, i would like to confirm whether PWHT is mandatory as per UCS-56-4 ?

Can we avoid PWHT for this 10mm weld joint ?

Or Should we do buttering with ERNiCr-3 on P No.5A bevel and butt weld 

with same filler for this dissimilar joint to avoid PWHT after making new 

PQR with buttering?

Please confirm soon.

Thanks and Regards,

Saravanan Sornam,

ANSAN-Si,

S.Korea
