  •         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.

    Expertise is undeniably evident in China’s approach to welding electrode production. China's engineers and material scientists dedicate significant resources to research and development, further propelling the industry forward. Innovative advancements, such as the development of low-hydrogen welding electrodes, markedly improve weld integrity by minimizing the risk of hydrogen-induced cracking. Furthermore, electrodes specifically designed for use in challenging climatic conditions—where variations in humidity and temperature can be particularly problematic—demonstrate China’s commitment to catering to a wide range of market needs. This attention to detail highlights professional expertise and fosters continued global trust in China’s welding products.
