What is the term for a depression on the face of a fillet weld that reduces its cross-section?

1. Depressed bead

2. Excessive convexity

3. Insufficient throat

4. Insufficient leg

The correct answer is: Depressed bead

The term "depressed bead" refers specifically to a type of defect or characteristic in welding, particularly with fillet welds. In this context, it describes the scenario where there is a noticeable depression in the weld face that leads to a reduction in its effective cross-sectional area. This depression can negatively affect the strength and integrity of the weld. Understanding this term is essential for evaluating the quality of welds in construction and manufacturing. A depressed bead can indicate inadequate fusion or improper technique during the welding process. Ensuring proper weld dimensions and profiles is crucial for achieving the desired mechanical properties and ensuring structural reliability. Other terms like "excessive convexity," "insufficient throat," and "insufficient leg" relate to different types of weld imperfections or characteristics that also impact weld performance. However, they do not specifically describe the condition of creating a depression in the weld face that reduces the cross-sectional area like the term "depressed bead" does.
