E7018 (Welding Electrode)

E7018 is a type of welding electrode used to join metal pieces together through a process called shielded metal arc welding. The "E" indicates it's an electrode, "70" signifies it provides a tensile strength of about 70,000 psi, and "18" refers to the 18 thousands of an inch at which it produces electrodes with specific properties. E7018 electrodes are known for their excellent weld quality, toughness, and low hydrogen content, making them suitable for structures requiring strong, durable, and high-quality welds, especially in low-temperature environments.
