SHARP - NICKEL
It is light coated, electrode depositing nickel. Specially designed for welding cast iron the cold way. The nickel weld deposit which bonds thoroughly with the cast iron, does not pick up carbon or any other element from the base metal and remains soft and tough. The weld deposit is machinable and its tensile strength is adequate for cast iron.

Special Instructions for Welding Cast Iron Electrodes:
Point up with the electrode. Grind or chisel. Drill our any cracks which may end in the workpiece to prevent further cracking. Remove any casting scale present. Pre-heat hollow bodies or stress-prone and complicated workpieces to 200 to 250°C. With pure nickel or nickel-copper consumable materials, weld absolutely not more than 10 times the electrode diameter after each other (30 to 50mm). Hammer out the welding beads immediately to re
