ED511032 - Lincoln Jetweld E7024-1 High Deposition Stick Electrode 3.2mm

Technical Overview: Lincoln Jetweld 7024-1

The Lincoln Electric Jetweld 7024-1 is a high-efficiency, iron powder, titania-type stick electrode designed for the Shielded Metal Arc Welding (SMAW) process. Engineered to meet the AWS A5.1 E7024-1 classification, this electrode distinguishes itself from standard E7024 consumables by offering verified impact toughness properties, specifically Charpy V-Notch values at -18°C (0°F). This makes it suitable for structural applications where ductility and resistance to brittle fracture at lower temperatures are engineering requirements, alongside the traditional benefits of high-speed deposition.

The 3.2mm (1/8") diameter configuration is optimized for heavy fabrication environments. The coating contains a high percentage of iron powder, which contributes to the weld pool, significantly increasing the deposition rate compared to non-iron-powder electrodes like E6013 or E6010. This results in higher travel speeds and increased productivity for long fillet welds in the flat and horizontal positions. The electrode operates with a smooth, quiet arc and produces a fluid puddle that wets out exceptionally well, minimizing undercut and ensuring good fusion at the toes of the weld.

Operable on AC, DC+, and DC- polarities, the Jetweld 7024-1 offers versatility in power source selection. However, it is strictly limited to flat and horizontal fillet positions due to the large volume of molten metal and fluid slag system. The slag is dense and typically self-releasing, reducing post-weld cleaning time and labor costs. Mechanical properties include a minimum tensile strength of 70,000 psi, aligning with mild steel structural requirements. Industrial applications include earthmoving equipment manufacturing, structural steel fabrication, barge construction, and general heavy machinery repair where high deposition rates are prioritized.
