Equally important is the range of welding electrodes available. A comprehensive supplier should offer a variety of options tailored for different metals and use cases, such as mild steel, stainless steel, cast iron, and specialty alloys. This versatility empowers welders to tackle a diverse range of projects, from construction to intricate metalwork. Moreover, a supplier with a broad product catalogue will also have electrodes designed for specific requirements like high moisture resistance, low hydrogen levels, and superior tensile strength, hence ensuring adaptability to any welding challenge.

        Cast iron welding rod is a welding rod used for cast iron, characterized by high strength and good plasticity. It is suitable for gray cast iron and ductile iron, and can be machined.
        Cast iron is usually classified according to the distribution of carbon in cast iron, and can generally be divided into white cast iron, gray cast iron, ductile cast iron, vermicular cast iron and malleable cast iron. Due to the high carbon content, uneven structure, low plasticity and poor weldability of cast iron, it is very easy to produce defects such as white cast iron, cracks and pores during welding. Special attention should be paid to the selection of welding process and welding materials during welding. For welding rod arc welding, it can basically be divided into two categories, one is the homogeneous weld type, namely cast iron type; the other is the heterogeneous weld type such as: steel (carbon steel or alloy structural steel, etc.), pure Ni (pure nickel 308), Ni-Fe (nickel iron 408), Ni-Cu (nickel copper 508), Ni-Fe-Cu, Fe-Cu, etc. When selecting welding rods, you can choose according to different cast iron materials, different cutting requirements, different service conditions and importance, different structural characteristics, stiffness, etc.
