Which positions are the E7025 electrode allowed to be used in?

• A. The flat and horizontal fillet positions only
• B. All positions
• C. Horizontal and vertical fillet positions
• D. Vertical and overhead positions

Answer: (A)

The key idea is that some electrodes are approved for use only in certain welding positions. The E7025 electrode is designed and tested for flat and horizontal fillet welds, and its flux and arc characteristics are optimized for those orientations. In those positions, gravity helps the molten metal and slag behave predictably, producing a stable bead with good fusion and minimal defects. When you try to weld in vertical or overhead positions with this electrode, the slag can become heavy, the weld pool can sag or run, and wetting and fusion may deteriorate, leading to porosity or slag inclusions. Because of these limitations, E7025 is restricted to flat and horizontal fillet welds. For vertical or overhead work, a different electrode rated for those positions should be used.
