What is a defective property?

• A. Any deviations in the mechanical and chemical properties of a weldment
• B. An improvement in surface finish
• C. Increased ductility
• D. A weld with perfect properties

Answer: (A)

A defective property means any deviation from the specified mechanical and chemical properties of a weldment. Welds are expected to meet defined limits for strength, hardness, toughness, and chemical composition. When a property falls outside those limits, the weld doesn’t meet the requirements and is considered defective. Desirable changes like better surface finish, more ductility, or a weld with perfect properties are not defects because they align with or exceed the specs.
