Primary Electrode: Page 1-24
Alternate Electrodes: Pages 1-5, 1-3
Welding Procedures: Do not rebuild rails until they
have worn to recommended service limits. Buildup
outside edges to same level as center. Apply wash
passes 1/2 in. wide until entire surface is covered.
Work alternately on four links to avoid overheating.
Use only buildup materials; do not hardface (Figure
2-7).
