Multiple tapping method for non-destructive testing of defects in metal components

Key Points

• Defect detection in metal components improves using a multiple tapping method, enhancing reliability.
• A significant detection rate was recorded based on acoustic signals after 30 trials per sample.
• Observational analysis evaluates the non-destructive testing methods to assess metal integrity and identify defects.
• Utilizing this technique may streamline quality assurance processes in manufacturing, promoting better safety standards.
