Lack of Fusion in Welding: Why a Good-Looking Bead Can Still Fail
In modern industrial manufacturing, visual inspection alone can be dangerously deceiving. A weld bead can present a smooth, uniform profile while concealing a critical structural defect beneath the surface. The reality is straightforward: a visually pristine weld is not inherently a structurally sound weld. While external bead geometry indicates proper metal deposition, weld integrity hinges […]
