Cast iron welding filler code ER-Ni1 , Iran

The cast iron welding filler with the code ER-Ni1 is one of the most commonly used filler materials in the cast iron welding process, primarily utilized for repairing cast iron parts. This filler is made of high-purity nickel and, due to its excellent adhesion to the cast iron surface, can withstand thermal and mechanical stresses effectively. ER-Ni1 has an appropriate melting point that helps prevent cracking and maintain weld integrity during cooling. This filler is suitable for various types of cast iron including gray cast iron, ductile cast iron, and white cast iron, and due to its wear resistance and good corrosion resistance, it increases the service life of repaired components.

In terms of application, ER-Ni1 is widely used in industries such as automotive, machinery manufacturing, and industrial installations, especially when welding hard and brittle cast irons is required. International welding standards like AWS A5.14 and ISO 17632 define the technical specifications of this filler, including a chemical composition with a high percentage of nickel, tensile strength, and acceptable mechanical properties. Additionally, ER-Ni1 supports welding with TIG and MMA methods, and due to its ease of use and weld quality, it is considered one of the top choices among professional welders. Proper use of this filler leads to improved quality and durability of cast iron welds.
