Manual arc welding, repair welding cast iron piece with the electrode. According to weld 928 points, there are mainly five types of electrode:
(1) pure nickel class cast iron electrode. Electrode made of pure nickel weld core and graphite-type coating, weld nickel-containing more than 90%, mainly for difficult welding Welding malleable cast iron and alloy cast iron.(2) nickel-iron type cast iron electrode: the electrode made by the core of nickel-iron Welding Electrode and graphite type coating, containing nickel in the weld in about 50% of soil to be used for repair welding of ductile iron.
(3) of nickel and copper in class cast iron electrode. Nickel-containing welding nickel-copper alloy (monel) core and the electrode made of graphite-type drug skin, the weld 60% to 70%, copper 25% and 35% for repair welding of gray cast iron.
(4) cast iron cast iron electrode. Cast iron welding core electrode made of carbon steel welded core and graphite type coating, weld composition of cast iron composition is close to gray cast iron and nodular cast iron welding repair welding should preheat to 400 ~ 500 ℃ , slow cooling after welding insulation.
