86545 - Bohler Fox 6010 3.2mm Cellulose Pipe Electrode

Technical Overview of Bohler E6010 3.2mm Electrodes

The Bohler 86545 (E6010) is a high-quality cellulosic sodium-coated stick electrode designed specifically for the Shielded Metal Arc Welding (SMAW) process. Engineered for deep penetration and fast-freezing weld puddles, this 3.2mm (1/8 inch) electrode is a staple in the pipeline and construction industries. It meets AWS A5.1 specifications for E6010 classification, ensuring consistent mechanical properties and performance. The electrode operates on Direct Current Electrode Positive (DCEP), providing a digging arc that effectively cuts through rust, scale, paint, and oil, making it highly suitable for maintenance and repair operations where surface preparation may be minimal.

One of the defining characteristics of this Bohler electrode is its suitability for vertical-down welding. The fast-freezing slag system allows operators to control the weld pool effectively in out-of-position welds, particularly for root passes on pipe. The arc force is strong and stable, facilitating excellent fusion and bridging of fit-up gaps. Metallurgically, the deposit offers good ductility and radiographic quality, essential for pressure vessel and critical piping applications. Storage recommendations typically involve keeping the electrodes in a dry environment, though unlike low-hydrogen rods, cellulosic electrodes generally do not require high-temperature rebaking if stored correctly; in fact, excessive drying can degrade performance.

The 3.2mm diameter is versatile, capable of handling a wide range of wall thicknesses. It is optimized for use in all welding positions—flat, horizontal, vertical, and overhead. This flexibility, combined with its aggressive cleaning action and deep penetration profile, makes the Bohler E6010 an indispensable consumable for professional welders in the oil and gas, shipbuilding, and structural steel sectors.
