Which of the following is a common fabrication defect?

Weld spatter is classified as a common fabrication defect primarily because it occurs during the welding process when molten metal is expelled from the weld pool and solidifies on the surrounding surface. This can create uneven surfaces and potentially affect the integrity of the weld joint. If not removed or properly managed, weld spatter can lead to issues with adhesion for coatings applied later and can detrimentally impact the aesthetics and performance of the finished product.

Corrosion, while a significant concern in the life cycle of a coated item, pertains more to wear and environmental degradation after fabrication rather than defects that occur during the manufacturing process. Peeling is associated with issues in the coating or paint film due to improper application or surface preparation, which similarly does not reflect a fabrication defect directly. Fading is related to the degradation of coating color and properties over time due to exposure to environmental factors, which is a post-fabrication issue rather than a defect resulting from the initial fabrication process.

Therefore, weld spatter stands out as a defect that originates during the fabrication phase, highlighting its significance in quality control within the welding stage of fabrication.
