What type of welding is E7018 commonly used for?

• A. Arc welding
• B. Gas welding
• C. Resistance welding
• D. TIG welding

Answer: (A)

E7018 is a type of welding electrode that is primarily used in arc welding processes. It is a low hydrogen electrode, which means it is designed to produce high-quality welds with excellent strength and ductility. The designation "E7018" indicates its welding characteristics, where "E" stands for electrode, "70" denotes the minimum tensile strength in KSI (70,000 psi), and "18" refers to the type of coating and the polarity used. In arc welding, an electric arc is generated between the electrode and the workpiece, melting both the electrode and the base metal to create a strong joint. E7018 is particularly valued for its ability to perform well in applications that require high strength and resistance to cracking, making it a popular choice for structural applications in construction and heavy manufacturing. Other types of welding, such as gas welding, resistance welding, and TIG welding, utilize different methods and materials that may not achieve the same results as E7018 in terms of weld quality and performance, making arc welding the appropriate context for this electrode.
