76306 - Bohler 4.0mm E7018-1 Low Hydrogen Welding Rods

Premium Bohler E7018-1 Stick Electrodes for Critical Applications

The Bohler E7018-1 4.0mm Stick Electrode is a high-performance, basic-coated consumable designed for the most demanding steel fabrication tasks. Engineered by Bohler Welding, a global leader in joining technology, this electrode is formulated to deliver exceptional weld quality with superior mechanical properties. The "-1" designation indicates that this electrode meets stricter impact toughness requirements at lower temperatures compared to standard E7018 rods, making it the preferred choice for projects requiring high structural integrity in challenging environments.

This unalloyed, low-hydrogen electrode excels in welding carbon steels, particularly those with higher carbon content or lower purity where cracking is a concern. Its basic coating provides a smooth, stable arc and produces a weld deposit with very low diffusible hydrogen levels, significantly reducing the risk of cold cracking (hydrogen-induced cracking). This makes it an essential consumable for heavy industries such as offshore construction, boiler manufacturing, and pressure vessel fabrication.

Superior Weldability and Versatility

Welders will appreciate the operator-friendly characteristics of the Bohler E7018-1. It offers excellent control in all welding positions (except vertical down), allowing for high-quality results even in difficult joints. The slag system is designed to be easily detachable, reducing post-weld cleanup time and improving productivity. The 4.0mm diameter is ideal for filling joints in thicker plate sections, providing good deposition rates while maintaining manageable heat input.

Target Applications

These electrodes are specifically engineered for sectors where safety and durability are paramount. Common applications include:

• Offshore Structures: Platforms and rigs requiring high impact strength at sub-zero temperatures.
• Pressure Vessels & Boilers: Critical joints subject to high pressure and thermal stress.
• Heavy Machinery: Earthmoving equipment and cranes where dynamic loading occurs.
• Structural Steel: Bridges and high-rise buildings requiring code-compliant welds.

Whether you are repairing heavy equipment or fabricating new infrastructure, the Bohler E7018-1 4.0mm electrode provides the reliability and consistency professional welders demand. Ensure your welds meet the highest standards of safety and performance with Bohler's trusted technology.
