Question 1987 Deck Safety

The correct answer is C) Ultrasonic. Ultrasonic testing is a non-destructive weld inspection method that can detect internal flaws and defects within the weld material. It uses high-frequency sound waves to penetrate the weld and identify any discontinuities or imperfections that may not be visible on the surface. This makes ultrasonic testing an effective technique for identifying internal defects that could compromise the structural integrity of the weld. The other options are not suitable for detecting internal weld flaws. Chemical reaction testing is used to analyze the chemical composition of the weld, magnetic particle testing detects surface and near-surface defects, and dye penetrant testing is used to identify surface-breaking flaws.
