DESCRIPTION:
VC-50 is a high grade special purpose electrode with ferro-nickel alloy core (Fe45%Ni55%). This electrode is specially intended for cold welding of cast iron. Due to the special character of the coatings, welding can be completed by lower current compared with the conventional electrodes. So, the weld metal can be machined by cutting tools and is not sensitive to cracking. As the weld metal has excellent mechanical properties, it is most suitable for cold welding of ductile cast iron (nodular cast iron).
APPLICATIONS:
For welding of nodular cast iron, repairing and joining of all kinds of cast iron. Also suitable for underlaying of hardfacing.
INSTRUCTIONS FOR WELDING
1.) As a rule, no preheating or postheating is necessary, but the best result is obtained when the parent metal is heated to 100 - 200ºC before welding.
