*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 thick-
ness. 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 atmo-
sphere for up to ten hours with no harmful effect.
Reconditioning schedules should come from the man-
ufacturer.
