What are graphite welding rods used for?
Graphite welding rods are used primarily for welding cast iron. Cast iron is a notoriously difficult material to weld due to its high carbon content, which makes it prone to cracking and difficult to manipulate. Graphite welding rods, also known as "graphite electrodes," provide a solution to this problem.

When used in welding, the graphite rod acts as both an electrode and a filler material. The graphite electrode generates intense heat, which helps to melt the surrounding cast iron, while the graphite filler material mixes with the molten metal, providing reinforcement and helping to control the cooling process, thereby minimizing the risk of cracking.


Overall, graphite welding rods enable welders to effectively join pieces of cast iron together, making them a valuable tool in industries where cast iron components are common, such as automotive, manufacturing, and construction.
