Haihao Group introduces welding rods and their classification to you

As an expert in the field of pipeline systems, Haihao Group not only produces and sells high-quality pipeline system supporting products, but is also proficient in various pipeline-related technologies, including welding and coating technologies. In the welding process, welding rods are one of the crucial materials, so we have an in-depth understanding of welding rods and their classification.

PIPING PRODUCTS

A welding rod is a molten electrode used for arc welding, usually consisting of a welding core and a coating. The welding core is the metal core of the welding rod, and the coating is the active ingredient coated on the surface of the welding core. Different types of welding rods have different welding cores to ensure the quality and performance of the weld. The welding core not only conducts current to generate an arc, but also melts the filler base material to form a weld.

The coating of the welding rod plays an important role in the welding process. It protects the molten metal, removes gases and impurities, provides alloying elements, and improves arc stability. In addition, the coating can also insulate the weld metal and reduce the cooling rate, which is beneficial to the welding quality.

According to different uses and chemical compositions, welding rods can be divided into many types, including carbon steel welding rods, low alloy steel welding rods, stainless steel welding rods, chromium and chromium molybdenum heat-resistant steel welding rods, aluminum and aluminum alloy welding rods, nickel and nickel alloy welding rods, etc. . In addition, according to the acidity and alkalinity of the slag formed after the coating is melted, the welding rod can also be divided into alkaline welding rod and acidic welding rod.
