For Drying is only for control of Hydrogen induced crack in the weld metal , For that only Low hydrogen electrodes are to be Baked & Dried. It will not affect the Chem & Mech properties.

Subject: [MW:7196] use of E 7018 Electrode for stuructural welding without proper drying and holding
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
Asad Azmi
