E-7018-1 is better then E7018

[Ghulam Mustafa]

Dear All,

Hope you are fine.

i want discuss that i was gone yesterday for inspection in other company as a third party, i checked WPS for welding inspection, during inspection i observed that welder used E7018-1 Electrode instead of E7018 on structure. structure material A572 Grade-B and A-36. E7018-1 can problem or not?

can any one tell me about this problem.

The difference between E 7018 and 7018-1 is the impact test temperature, so 7018-1 is better than 7018

only difference is impact test temprature.

Dear ,

There is no problem, basically E7018-1 electrode used for Impact Value.

Better performance in low temperature. Same A and F-no

Consider it to be a premium subset of the E7018.  Basically same properties but with chemistry optimized to achieve low temperature impact properties.  It is generally acceptable to use E7018-1 in lieu of E7018 unless customer has specific requirements regarding qualification. 

 

Code is fun. Enjoy.

Hi Ghulam,

E 7018-1  electrodes contains more Mn than E-7018 electrode, at the same strength(UTS) level, 70 Ksi. The advantage is better impact . Typically E-7018-1 are designed for impact up to -46 Deg c , while the same for E-7018 is up to -29 Deg C.

In order to avoid duplicity or redundant work nowadays  it’s very commons for electrode manufacturers to classify same welding electrode as E-7018-1/E-7018, which is called dual certification.

Please look at the highlighted text from, SFA 5.1 , Sec-II, Pt-C, on E-7018-1 welding electrodes.

As the mechanical and other properties of the deposited are not changed, a change from E-7018 to E-7018-1 , will not cause any harm the welds . However if should be addressed in WPS or regularized through an NCR.

 

Thanks

When subjected to SR, 7018-1 gives better mechanical value compared to 7018 due to more manganese in -1. Better ductility , cost is more

Hi Mr. Goswami,

Please can you throw some Light on the Manganese content of E7018 & E 7018-1 as AWS 5.1 restricts Manganese to 1.6% and what will happen if increased beyond this range.

Thanks & Regards

E7018-1 is good weld ability for above 32 thickness, last month in structural I welded E7018 for 32mm thk web with 32mm thk flange IS2062 all the fillet joint CRACKED immediately. So after that we used E7018-1 no crack observed.
