WELDING PARAMETERS
*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.
SPECIFICATIONS - FRAME DIMENSION
Frame dimensions are listed in metric scale. All dimensions are from center to center of Principal Locating Point (PLP), or from center to center of PLP and fastener location.
