*First choice - Gas Metal Arc Welding Process: Butt joints - apply two layers (passes) of weld metal. First pass should only fill approximately 1/2 the thickness. Vertical position welds - maintain electrode wire at leading edge of weld puddle while traveling down hill to produce maximum penetration into the sleeve. These techniques work for FCAW as well.
**E7018 new electrodes may be exposed to the atmosphere for up to ten hours with no harmful effect. Reconditioning schedules should come from the manufacturer.
