[MW:9561] Requirement of suitable welding consumables SAW and SMAW

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.

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.

With Regards,

Muthu Barathi P

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.

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
elongationis not required for the weld.
Thank you.

Best regards.
PJA

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,
