The Bohler E7018-1 is a premium basic-coated, low-hydrogen stick electrode designed for the shielded metal arc welding (SMAW) of carbon and low-alloy steels. Engineered to meet the rigorous requirements of the AWS A5.1 E7018-1 classification, this electrode provides exceptional mechanical properties, specifically high impact toughness at temperatures as low as -45°C. The 2.5mm diameter is optimized for precision work on thinner sections or for root passes in heavy wall pipes and plates.
Metallurgically, the electrode deposits a weld metal with very low diffusible hydrogen content (typically less than 4ml/100g), significantly reducing the risk of hydrogen-induced cracking (cold cracking) in the heat-affected zone (HAZ). This makes it a preferred choice for welding fine-grained structural steels and restrained joints where stress concentrations are a concern. The coating formulation ensures a stable arc on both DC+ and AC polarities, providing versatility across different power sources.
The electrode exhibits excellent operability in all positions, including vertical-up, with a concentrated arc that ensures deep penetration and reliable fusion. The slag system is designed for easy removal, often self-releasing, which improves productivity by reducing post-weld cleaning time. It is particularly suited for industries requiring high radiographic quality, such as offshore fabrication, pressure vessel manufacturing, and pipeline construction.

The Bohler E7018-1 Stick Electrode (2.5mm) is a high-performance, basic-coated consumable designed for the Shielded Metal Arc Welding (SMAW) of unalloyed and fine-grained steels. Engineered by Bohler Welding, a global leader in joining technology, this electrode is formulated to deliver exceptional mechanical properties, particularly in applications requiring high impact toughness at low temperatures. The "-1" suffix in the AWS classification indicates that this electrode meets rigorous impact requirements, ensuring reliable performance in environments where structural integrity is paramount.
This electrode features a basic coating that produces a weld metal with very low hydrogen content, significantly reducing the risk of cold cracking (hydrogen-induced cracking) in thick sections or restrained joints. It is particularly adept at handling steels with lower purity levels or higher carbon content, where standard electrodes might fail. The 2.5mm diameter allows for precise control in root passes and thinner sections while maintaining the deposition efficiency expected of a 7018 class rod. It operates effectively on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing versatility across different power sources.
Ideally suited for heavy industrial sectors, the Bohler E7018-1 is a staple in offshore construction, boiler and pressure vessel manufacturing, and heavy vehicle fabrication. Its ability to produce X-ray quality welds makes it the preferred choice for code-work and safety-critical infrastructure. The slag system is designed to be easily detachable, leaving a clean, smooth bead profile that requires minimal post-weld cleanup. While it is an all-position electrode, it is optimized for flat, horizontal, vertical-up, and overhead positions, excluding vertical-down.
