Cast iron electrode is a kind of welding material used for welding cast iron materials. The electrode is melted by heat energy and connected with the cast iron workpiece to achieve the purpose of welding.

The working principle of cast iron welding rod is mainly to use its melting characteristics and compatibility with cast iron materials. First, when the cast iron electrode is exposed to high temperature, such as heating by electric welding equipment or flame, the electrode will gradually melt. The molten electrode forms a liquid metal, called slag, which can connect the cast iron workpiece and the electrode at the welding site.
Secondly, the compatibility of cast iron electrode and cast iron material is also an important factor in welding. The composition of the cast iron electrode is similar to that of the cast iron material, which can be well integrated with the cast iron workpiece and form a strong connection. In the welding process, the welding rod will cool and solidify with the surface of the cast iron material after melting, forming a layer of welding area, so that the strength of the welding part is enhanced.
In general, the working principle of cast iron welding rod is to realize the connection and alloying between the two by melting the welding rod and connecting it with the cast iron workpiece, so as to complete the welding repair or reinforcement of the cast iron material. In practical application, it is very important to select the appropriate cast iron electrode and master the correct welding technology to achieve high-quality cast iron welding.
