[MW:18457] RE: 18456] Re: May E8018-C1 substitue E8018-G to weld Corten Steel

Hi Abuzar,

 

The default electrodes for these grades of steel is E-8018-W2/W1. However some electrode manufacturers may market this product under "G" classification. As per ASME Sec II part C, the "G" classification should meet the nominal chemistry in  specified in SFA 5.5.The additional alloying elements are acceptable  subject to mutual agreement between the manufacturer and the user.

 

If E-8018-G matches the chemistry of E-8018W2(for Corten -B) and E-8108-W1(for Corten-A), then the deviation may be allowed. You have  to compare the MTR's of both types of electrodes to arrive at a conclusion.

 

 

Thanks

Hi all

For welding Corten steel, we have in storage E8018-C1 Electrod, may it substitue  E8018-G, how can confirm ?
