What is a common indicator of a defect found during visual inspection of welds?

During a visual inspection of welds, irregular indications are a common indicator of defects. This is because the quality of the weld should ideally present consistent and predictable characteristics such as smoothness and regular bead patterns. When irregularities are observed, they may suggest issues like poor fusion, inclusions, or undercuts. These anomalies can compromise the structural integrity of the weld, making it essential for inspectors to identify and address any irregular indications as they may reflect potential weaknesses in the weld. The presence of irregularities serves as a key prompt for further investigation or corrective actions to ensure the safety and reliability of the weld.
