Why is cast iron not weldable?

Cast iron is a type of iron-carbon alloy that is widely used in various industries due to its strength, durability, and resistance to wear and tear. However, cast iron is not weldable using traditional welding techniques, such as gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), or shielded metal arc welding (SMAW).

The reason behind this is the high carbon content in cast iron, which makes it brittle and prone to cracking during the welding process. The carbon content in cast iron ranges from 2% to 4%, which is higher than the carbon content in steel. This high carbon content also makes cast iron more susceptible to decarburization, a process that occurs during the welding process, where the carbon content at the weld bead is reduced, leading to a weaker and more brittle structure.

Moreover, the high carbon content in cast iron also leads to the formation of iron carbide, which is a brittle compound. During the welding process, this compound expands rapidly, leading to cracking and spalling of the weld bead. Additionally, the high carbon content causes the cast iron to have a lower melting point than steel, making it more prone to distortion and warping during the welding process.

To overcome these challenges, alternative welding techniques such as induction welding or resistance welding can be used for cast iron. These techniques are less likely to cause cracking and decarburization due to lower heat input and shorter welding times. However, these techniques have their own limitations and may not be suitable for all applications.

In summary, the high carbon content in cast iron makes it challenging to weld using traditional welding techniques due to the risk of cracking, decarburization, and distortion.
