Which of the following is NOT typically a defect found in welds?

• A. Porosity
• B. Cracks
• C. High gloss finish
• D. Lack of fusion

Answer: (C)

In welds, a high gloss finish is generally not classified as a defect. Instead, a glossy appearance can often be associated with proper welding techniques and well-controlled parameters that contribute to the overall aesthetic quality of the weld. This glossiness may result from a clean weld that exhibits smoothness and minimal oxidation, indicating a good quality weld. On the other hand, porosity, cracks, and lack of fusion are recognized weld defects that can compromise the strength and integrity of a welded joint. Porosity refers to small gas bubbles trapped within the weld metal, which can weaken the structure. Cracks can occur in the weld or the heat-affected zone, leading to potential failure under stress. Lack of fusion indicates that there was insufficient melting of the base metal or filler material, preventing a strong bond. Understanding these defects is essential for ensuring the quality and reliability of welds in various applications.
