Re: [MW:7214] use of E 7018 Electrode for stuructural welding without proper drying and holding

Dear Azad..

 

Baking & drying is required for the basic electrodes like E 7018 to reduce the hydrogen content in the deposited weld metal. If you are not doing any baking there by you are improving the condition for hydrogen cracking the weld metal.

 

You have mentioned that you are using E 7018 for the angle bar welding .. normally for structural purpose you can proceed with rutile electrodes like  E 6013 which needs to be dried only.

 

best regards,

Dear All,

 

Goodday.

 

 

what will be the effect in Mechanical/chemical proerties of deposited weld metal of  E7018 which is used for Structural welding of angle bar( material CS) without drying  (at 260-430deg C) and Holinding(at 120 deg C).

 

 

Can E7018 be used without proper drying and holding for stuructural welding( fillet weld only) of angle bar/supports(material CS).

 

 

Thanks in advance for your valuable suggestions.

 

Best  Regards
