Root penetration
WebAug 6, 2024 · Excessive root Penetration, Drop Through and Burn Through. Excessive penetration is the exact opposite of Incomplete penetration. Excessive penetration appears on the root of the weld where the weld metal appears to be too high, the welder is moving or manipulating the welding rod too slowly, or the current is too high. With limited sensory input, roots must navigate an environment containing heterogeneities such as rocks and compaction. The ability of roots to penetrate soil is crucial for water and nutrient uptake as well as mechanical anchorage. Here, we describe a molecular framework controlling helical root growth known as circumnutation.

It’s measured on the centerline of the root cross-section (Figure 11). The minimum depth a groove or flange weld extends from its face into a joint, exclusive of reinforcement. Joint penetration may include root penetration as in Views A, C, and E.
