DESCRIPTION
VHF-600 is a lime type electrode, depositing weld metal typical martensite structure. As-welded condition it shows high hardness, and is suitable for soil abrasion and light impact abrasion. Machining is impossible as welded condition.
APPLICATIONS
Hard surfacing of bulldozer links, bucket edges and dipper teeth, etc.
INSTRUCTIONS FOR WELDING
1.) Preheat at 150ºC and over in general.
2.) It is recommended to underlay with low hydrogen type electrode (N-7016 or N-7018) in case the base plate is hardenable or multi-layer welding is required.
3.) Dry the electrodes at 300~350ºC for 30~60 minutes before use.
