WebFeb 12, 2024 · Aluminum will begin to deposit on the surface of the electrodes which can occur in as little as five spot welds, creating irregular intervals that require constant inspection. If the electrodes are contaminated, the probability of a defect occurring within the weld increases significantly. WebApr 14, 2024 · Examine the quality of the welding bead produced by the rod. A good welding rod should produce a smooth, even, and well-penetrated weld bead with good fusion between the base metal and the filler metal. If the weld bead is uneven, has poor fusion, or appears porous, it may indicate a bad welding rod. Difficulty in Striking an Arc
