Hi

 

The elongation requirement is very stringent, it is very difficult to meet 46%, you have consult with the specific consumable suppliers to get 46%

 

Thanks & Regards,

Hello there!

 

This material is very strong one. I think the welding consumable suppliers can best answer this question.

My understanding is that the percentage elongation is not required for the weld.

Thank you.

 

Best regards.

Mr. Muthu,

 

What's the applicable specification for this material, ASTM/ASME/EN or any proprietary grade for any client or any vendor's specification.The elongation and impact properties asked are highly un-realistic. You never get a Carbon or Low Alloy steel with 46% elongation requirement, also, impact requirement is extremely high.

 

I would say, if you have any design paper work, which indicates the grade or heat treatment of this steel the correct AWS type of welding consumables, SAW wire+flux specification  etc could be worked out. Otherwise YOU SHOULD NEVER CHOOSE WELDING CONSUMABLES BASED ON THE CHEMICAL COMPOSITION ALONE.

 

Thanks.

[muthu barathi]

Dear Sir

Actually this material is for Piling work. We are constructing a new
jetty . Steel Pile material is API - 5 L PSL - 2 / Grade X-65 . Pile
size OD - 1219mm and wall thickness - 22.22mm and also other size OD -
914mm and wall thickness - 22.22mm.

Now I want make a WPS by carrying out PQR . So I am searching based on
the sample pipe's MTC. The reading I have given is replica of MTC and
the is certified by Lloyds Surveyor too.

Now please tell me the correct welding electrode for SMAW and wire and
flux for SAW process. As per API 5L PSL 2 / Grade 65. the requirement -

X 65 - YS - 448 MPa. TS - 531 MPa. EL% - 23 - Impact at 0 deg.C
27 Joules. C - 0.22 Mn - 1.45 P- 0.025
S- 0.015 Ti - 0.06


Approved brands electrodes - ESAB and OERLIKON from these consumables
shall be selected.

While testing PQR it should not fail.

Expecting your mail shortly.

Thanking You.

Be explicit about your question
Open-ended questions tend to be perceived as open-ended time sinks.
Those people most likely to be able to give you a useful answer are
also the busiest people.
You are more likely to get a useful response if you are explicit about
what you want respondents to do (provide pointers, send info,
whatever). This will focus their effort and implicitly put an upper
bound on the time and energy a respondent must allocate to helping
you. This is good.
To understand the world the experts live in, think of expertise as an
abundant resource and time to respond as a scarce one. The less of a
time commitment you implicitly ask for, the more likely you are to get
an answer from someone really good and really busy.

Dear Mr. Muthu,

It seems you need a usual welding material like E71T-1M/E71T-1

Betreff: [MW:9550] Re: Requirement of suitable welding consumables SAW and
SMAW for API 5L X65

--

[praveen alavandar]

Mr.Muthu,

Since your material is API 5L X65 you can try the following combination,

1. SMAW - E 8018 G (OK 74.70) from ESAB - Take it from Sweden plant.

2. SAW consumables from Lincoln Electric.

AWS Class F8A/P8 - E Ni5 - Ni5

Trade Names
P240 - Flux
LNS 165 - Wire

From the chemical composition you listed, the Carbon Equivalent value comes to around 0.38.

Preheat the joint around 100 Deg. C, Interpass 250 Deg.C Max.

Since your Diameters are 48" and 36" are you going to back chip from the inside to ensure complete penetration? If yes then you can use OK 74.70.

I you dont have access towards the root side of the weld joint, I will recommend you to use ER 70S 6 or ER 70S2 (GTAW), do not use cellulose electrodes for the root passes.

What ever consumable that has been mentioned above, please make sure that all of them meets the minimum specified properties of the base material (X65).

Both the SMAW and SAW conusmables mentioned above will definitely meet your requirement of X65 and for ER 70S 6 or ER 70S 2 you'll have to talk to the manufacturer / dealer.

Make sure you get conusmable TC batch tested (Both mechanical and chemical), do not accept batch TC's showing typical values.

Hope this helps,

Regards,

A.Praveen

Dear Muthu,

 

Here are some recommended consumables for X-65 steel, from Oerlikon and ESAB. The highlighted text would be of interest. For SAW along with OP-121TT flux oerlikons' recommendation is with 2 types of welding fillers(see the attachment).

 

If there are  NACE sour service requirements than MAX Nickel content should be 1%.

 

I would try to look for suitable wire flux combination from ESAB and get back to you.

 

You may call the representatives' of ESAB and Oerlikon, in case you need any assistance.

 

Thanks.

[Fred Majdnia]

Dear All,

In selection of the consumables please take note of the following points:

- Piling for Jetty is normally done by Hydraulic hammers

- Welding is carried out in situ and at horizontal position and SAW may not be possible( depending on the depth of Pile penetration)

- Immediately after the weld cools down it shall be subjected to RT and Piling continues to prevent the pile stuck in formation

- There will be no access to the root for back welding /grinding

- Root weld should be a full penetration

 

If the length of the Piles are known to be below 24 meters they may be welded in shop and the above points may not be applicable.

 

Regards

Hi

You can use E 8018 for SMAW for API 5L X65. From ESAB it is available.

Hi Mr Pravin,

thank you. I have to run the PQR and the PQR has to pass the tests.

Now you have seen the MTC contents . please tell me while testing by
using the ok74.70 electrodes E8018G what reading we may ecept?

Mr.Muthu,   I have qualified and used these combinations on ISO 3183-3 L485MCS (API 5L X70 Equivalent) successfully.   Your PQR will get through comfortably for X65 grade.   As I have mentioned earlier in my mail, Your acceptance criteria of the PQR should as a minimum meet the minimum specified properties of the base material and any additional requirements imposed by your clients specifications.   I have attached a sample copy of OK 74.70 consumable TC for your reference, you can see the actual values of yield, tensile and impact properties of the particular batch of electrode is meeting your minimum requirement of X 65

YS - 448 MPa. TS - 531 MPa. EL% - 23 - Impact at 0 deg.C  27 Joules.

since the nickel is less than 1% you can use it for sour service as well, only care you should take is to make sure the capping pass HAZ doesnt exceed 275 HV, if at all sour service is imposed.

Hope this helps,   Regards,   A.Praveen Muscat

Mr. Praveen,

Thank you for your mail .

My base metal's physical properties as given below:

YS - 516MPa
TS - 6256MPa
El - 46%

But the consumables physical properties is

YS - 448 MPa.
TS - 531 MPa.
EL% - 23

While testing definitely it will fail in weld metal and PQR will not
pass.

This base metal will suit with ESAB OK 74.70 for SMAW and for SAW OK
AUTOROD 13.24 - F8A10 - EG-G.

This suits my requirement and now I am searching this consumables.
Being a slow moving item it is very difficult to get .I tried in Dubai,
Saudi all middle east and India. Not readily available.

Thanks to all my friends for given your valuable suggestions and
spending your precise time.

Mr.Muthu,   You mean to say that the PQR when qualified should meet or exceed the actual values mentioned in the MTC and not the minimum specified for the base material (X65).   I think such a requirement is very unusual, you can match the strength part, but I think its going to be a difficult task in locating a consumable to give you 46% elongation.   Wish you good luck!   Regards,   Praveen

Mr. Praveen ,
You are correct definitely we can not get El 46% but we can get YS and
TS with base metal matching by that way it will pass in TS and
naturally it will pass impact at -10 deg C so PQR will be passed.

Thank you
