*First choice—*Flux Cored Arc Welding Process: Butt joints - Vertical position welds - maintain end of electrode wire at leading edge
of weld puddle while traveling down hill to produce maximum penetration into sleeve. This technique works for Gas Metal Arc (MIG) as
well. Note: If MIG welding process is selected the galvannealed coating must be removed from both sides of the material adjacent to
the weld joint.
