RE: [MW:9530] Requirement of suitable welding consumables SAW and SMAW

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 elongation is not required for the weld.

Thank you.

 

Best regards.

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,

C - 0.066
Si - 0.26
Mn - 1.55
P - 0.014
S - 0.004
Al - 0.046
Cr - 0.186
Ni - 0.015
Mo - 0.002
Cu - 0.020
V - 0.057
Nb - 0.065
Ti - 0.020
N - 0.007
B - 0.00025
Ca - 0.0025
CE - 0.371

MECHANICAL PROPERTIES
YIELD STRENGTH - 516 MPa
TENSILE STRENGTH - 625 MPa.
ELONG % - 46
IMOPACT - (-) 10 DEGREE C - 250 JOULES

NOW PLEASE TELL ME, WHICH ELECTRODE FOR SMAW (BRAMDS ESAB, OERLIKON)
AND SAW - FLUX AND WIRE WILL SUIT AND PASS PQR TEST FOR PREPARATION OF
WPS?

PLEASE HELP.
THANKING YOU.



Dear Sir,





Thanking You,
