Bridge builders have trusted Atom Arc®
iron powder low hydrogen electrodes for 50 years for its superior welding performance, tough mechanical properties, crack resistance, high operator appeal and consistent quality. Used for everything from simple tacking operations to production welds, Atom Arc all-position electrodes are particularly useful in difficult-to-reach areas. These handy stick electrodes are portable for easy use in the field on out-of-the-way pipe or bridge work. Atom Arc is just as useful in the shop for welding components of all sizes and shapes. Welding engineers know that welds made with Atom Arc electrodes can be trusted to pass x-ray inspection and any other test specification they might encounter, no matter how rigid. Atom Arc, the original iron powder low hydrogen stick electrode, is the electrode of choice for critical weldments in carbon and low alloy steels.
Bridge builders appreciate Atom Arc’s smooth weld metal transfer over a wide operating range, excellent bead shape with little spatter, and complete slag coverage for minimal post-weld clean up. They also appreciate its superb mechanical characteristics, with a yield strength of 68,000 psi and tensile strength of 78,000 psi as welded. Atom Arc provides typical Charpy V-Notch impact properties of 18 ft.-lbs. (228 J) at -20º F (-29º C).
A number of additional formulations are available for special applications, high tensile steels, low temperature environments, and Chromium-Molybdenum alloys. Moisture resistant coatings are incorporated in all Atom Arc electrodes. These flux coatings are manufactured to effectively resist moisture and provide an extra degree of reliability, particularly for electrodes exposed to high humidity environments. Atom Arc meets AWS A5.1 and A5.5 specifications as well as military requirements for moisture control.
