For Rolling Friction
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 V-7016 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.
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.
DIRECTIONS
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%.
