what rod to use to weld cast iron_what rod to use to weld cast iron

In an era where information is abundant yet discerning quality is paramount, welding electrode manufacturers distinguish themselves by embodying the ideals of experience, expertise, authority, and trust. Through their innovative solutions, steadfast commitment to quality, and ethical practices, they earn their status not just as manufacturers but as trusted advisors and partners in the ever-evolving landscape of construction and manufacturing. Their products do not merely enable the construction of bridges and skyscrapers; they empower the architects of future progress, ensuring that each weld withstands the test of time.

        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.
