Atom Arc T was developed for welding T-1 steel in all applications. Mechanical properties of the welded joints equal or exceed the properties of the base steel in either the as welded or stress relieved condition, thus giving 100% design joint efficiency. In addition, Atom Arc T electrodes are suitable for many other applications, particularly where high-strength welds with excellent low temperature impact properties are required
- Medium penetration
- Moisture resistant coatings are incorporated in all AtomArc® electrodes
- The flux coatings are manufactured to effectively resist moisture pick-up in opened containers
- The improved coating provides an extra degree of reliability, especially for electrodes exposed to high humidity environments
- Moisture testing results are conducted in accordance with AWS A5.1 and A5.5 specifications
- AWS structural code allows a maximum of 0.4% moisture by weight for all E70XX electrodes
- Military requirements vary depending on the specific electrode classification
- Although moisture resistant coatings prolong the exposure time, storage and reconditioning should not be eliminated
- AtomArc® low hydrogen electrodes are available in a variety of strength levels and chemical analysis for welding almost every type of mild and low alloy steel
- With the introduction of these iron powder electrodes, fabricators can increase their productivity while reducing their overall welding cost
- This electrode is recommended for use in the weld repair and fabrication of Mn-Mo steel castings and armor plate
- 2.6 lb/hr at 120 amp, 2.7 lb/hr at 140 amp deposition rate, 71.6% at 120 amp, 70.9% at 140 amp efficiency
- Flat, horizontal, vertical up, overhead welding positions
