Which statement best describes how weld soundness is evaluated?

• A. Visual testing (VT) and applicable NDT per contract.
• B. By comparing to a reference color chart.
• C. By measuring the bead width.
• D. By the color of the coating.

Answer: (A)

Weld soundness is assessed by combining a visual check with nondestructive testing methods specified for the project. Visual testing looks for obvious surface flaws such as cracks, porosity, undercut, slag inclusions, or misalignment. To catch hidden or internal defects, applicable nondestructive testing (like radiography, magnetic particle, liquid penetrant, or ultrasonic testing) is performed according to what the contract requires. The chosen NDT methods and acceptance criteria come from project specifications and standards, so this combination provides a reliable evaluation of whether the weld will perform as intended. Color charts, bead width, or coating color do not reliably indicate weld soundness and thus aren’t sufficient by themselves.
