DESCRIPTION
VHF-260B is a titania type electrode which is designed to put prime importance on good usability and good machining property. It is suitable for reclaiming the light worn-out parts. Quenching after machining is also possible.
APPLICATIONS
Hard surfacing of gears, shafts and wheels.
INSTRUCTIONS FOR WELDING
1.) Preheating is unnecessary in general. But in the case of build-up welding of large cast steel and low alloy steel, need to preheat at 150~200ºC.
2.) The groove repairing is prone to slag inclusion, so adjust the holding angle of the electrode.
3.) Dry the electrodes at 80~120ºC for 30~60 minutes before use.
