Welding cast iron is a versatile substance that’s employed in producing various industrial goods with consequences in our day to day life.
With its exceptional fluidity, low melting point, the outstanding reaction to several layouts of this machine, it’s become understood as an engineering material and also can be employed in a selection of applications such as machines, pipes, and motor components, gearbox and other stuff for everyday usage.

It’s resistant to wear and deformation, but normally will be brittle, even though there’s malleable iron too.
An alloy of iron that has been liquefied by heating and poured into a throw to solidify and choose the form of the throw is that which we call cast iron.
The metal constituents have an effect on the color of the metal. White cast iron, that has impurities of carbide, gets white color when fractured. But, gray cast iron, that includes the carbon flakes of graphite, supposes a grey color in the lines.
Gray iron is the one which gets the largest applications. On account of the existence of carbon in the kind of graphite flakes, grey iron is not difficult to machine. Additionally, it has high compressive strength and can be normally responsive for welding.
Welding of cast iron substances
Gray cast iron is weldable with no reduction of underlying properties. Nonetheless, you need to preheat the projecting prior to fusion welding. If combination welding is the only option then you need to pick arc welding, because in arc welding, then the somewhat lesser level of preheating of this cast will burst.
Don’t try to weld grey iron castings which have chilled white cast iron surfaces, since this effort may impact the desirable properties of this white iron surface as a result of elevated temperatures of welding.
