DESCRIPTION:
VC-100 is a high grade special purpose electrode with pure nickel core. This electrode is especially intended for cold welding of cast iron. Due to the special character of the coatings, welding can be completed by lower current as compared with the conventional electrodes. The weld metal is the most insensitive to cracking and has good mechanical properties.
APPLICATIONS:
For repairing of cracks, filling of defects and joining of all kinds of cast iron. And also suitable for welding of the construction which water tightening is required.
INSTRUCTIONS FOR WELDING
1.) As a rule, no preheating or postheating is necessary, but the best result is obtained when base metal is heated to 100 - 200ºC before welding.
2.) Dry the electrodes at 80 - 120ºC for 30 – 60 minutes before use.
