61782400 - Bonarc E6010 2.6mm Red Flux Stick Electrodes

Technical Overview: Bonarc E6010 2.6mm Stick Electrode

The Bonarc E6010 is a high-cellulose, sodium-coated mild steel electrode designed for the Shielded Metal Arc Welding (SMAW) process. Classified under AWS A5.1 as E6010, this electrode is engineered to deliver a forceful, digging arc that achieves deep penetration into the base metal. The 2.6mm diameter is particularly well-suited for root passes on pipe and plate, as well as for welding on thinner gauge materials where control of the heat input is critical. The "Red Flux" coating identifies its specific formulation, which provides a stable arc and distinct operating characteristics preferred by professional pipe welders.

Operable on Direct Current Electrode Positive (DCEP), the Bonarc E6010 exhibits a "fast-freeze" solidification profile. This rheological property of the molten pool allows the operator to manipulate the weld metal effectively in out-of-position applications, including vertical-up, vertical-down, and overhead. The rapid solidification prevents the weld pool from sagging or dripping, ensuring high-quality bead profiles even in difficult orientations. This makes it an industry-standard choice for the root pass in API 5L pipe welding procedures.

In maintenance and repair operations (MRO), the chemical composition of the flux allows for welding on base metals that are less than pristine. The forceful arc action helps to burn through surface contaminants such as rust, mill scale, oil, and paint, reducing the need for extensive pre-weld cleaning. Mechanical properties meet or exceed AWS requirements for tensile strength (minimum 60,000 psi) and yield strength, providing reliable structural integrity for pressure vessels, storage tanks, and structural steel fabrication.
