I. APPLICATIONS:
Surfacing of rail roads, rail frogs, and switches, rail ends mini rails, ropeways rollers, touch flank of large gear wheels and gear rims, guide pulley on caterpillar vehicles.
II. DESCRIPTION:
A basic low hydrogen electrode for surfacing of abrasion due to rolling friction.
Applicable to steel with carbon content up to 0.45%. For higher carbon and alloy steels, apply a buffer layer of PA-52 to prevent cracking. Allow lateral weaving, hence broad, flat surfacing free of undercutting and spatter can be obtained. Its high deposition rate provide lower welding costs.
III. NOTES ON USAGE:
Use DC reverse polarity (DC+) or AC with minimum open circuit voltage (OCV) of 70V. Keep arc as short as possible. Preheating at 200ºC is recommended if carbon content exceeds 0.3%.
