On the other hand, E7018 electrode is typically used in the DCEP (Direct Current Electrode Positive) & AC polarity only. E7014 electrode is typically used in the DC+ (Direct Current Electrode Positive), DC- (Direct Current Electrode Negative), & AC polarity. Property E7014 Value E7018 Value Tensile Strength 70 Ksi (490 MPa) min 70 Ksi (490 MPa) min Yield Strength 58 Ksi (400 MPa) min 58 Ksi (400 MPa) min Elongation 17% min 22% min Toughness Not specified 15 ft lbf at –20☏ (20 J at –30☌), toughness requirements for E7014 welding rod are not specified in the AWS A5.1 specification.While 7018 welding rod has a weld toughness requirement of 15 ft However, E7018 has a higher elongation of minimum 22% compared to E7014 which has a minimum elongation of 17%. vs 7018 Tensile Strength & Mechanical Properties Comparisonīoth E7014 and E7018 welding rods have similar tensile and yield strength.

Read more: Different versions of E7018 Welding Rod: Both of these electrodes are covered by the AWS A5.1 specification, which covers carbon steel electrodes for shielded metal arc welding. 7014 vs 7018 SpecificationĮ7014 and E7018 welding rods are both types of shielded metal arc welding (SMAW) electrodes, which are used for welding low carbon steel. In this blog post, we will take a closer look at the similarities and differences between E7014 and E7018 welding rods, and help you to determine which one is the best choice for your specific welding need. However, there are some key differences between these two rods that make them better suited for certain applications & give them special features. When it comes to welding mild steel or low to medium carbon steel, two of the most popular electrodes that come to mind are E7014 and E7018.īoth of these electrodes are for stick welding or shielded metal arc welding (SMAW).
