E7018

E7018 is a type of welding electrode used to join metal pieces, primarily steel, through a process called arc welding. The "E" indicates it's an electrode, and "7018" specifies its strength and characteristics. This electrode produces a strong, durable weld that resists cracking and handles stress well. It also contains flux, a material that helps create a smooth, clean weld surface and protects it from oxidation during cooling. E7018 electrodes are commonly used in structural steelwork and construction because they provide reliable, high-quality welds suitable for load-bearing applications.
