Abstract:
1. A method of manufacturing a manual electrode for shielded metal arc welding with improved arc striking capabilities while minimizing said electrode sticking to a weldments during arc initiation through at least a higher current density for starting the welding arc for the welding of high tensile strength weldments, comprising the steps: extruding a contiguously formed metal core wire; dividing the contiguously formed metal core wire into finite length electrode cores; tapering at least one of the ends of each of the finite length electrode cores, thereby defining an electrode core body having a diameter D and an electrode core tip having a diameter D fashioning a flat on the at least one of the ends of each of the finite length electrode cores; coating the electrode core tip and electrode core tip taper with an electrically conductive substance comprising at least one of a silicate and graphite; and coating the electrode core body with a low hydrogen flux coating.
