4. Non-Destructive Testing (NDT):

– Ultrasonic Testing: Uses high-frequency sound waves to detect internal flaws.

– Radiographic Testing: Employs X-rays or gamma rays to reveal internal defects.

– Magnetic Particle Testing: Identifies surface and near-surface defects in ferromagnetic materials.

– Dye Penetrant Testing: Highlights surface-breaking defects using dye and developer.

5. Chemical Analysis: Verifies the composition of the metal using methods like spectroscopy to ensure it meets the specified alloy requirements.

Quality Control Methods:

1. Standard Operating Procedures (SOPs): Implement detailed SOPs for all processes to ensure consistency and adherence to standards.

2. Regular Calibration: Regularly calibrate testing and measuring instruments to maintain accuracy.

3. Training: Provide continuous training for employees on quality standards and testing methods.

4. Supplier Quality Management: Evaluate and monitor suppliers to ensure they meet required quality standards.

5. Statistical Process Control (SPC): Use SPC tools to monitor production processes and detect variations that could lead to defects.

6. Quality Audits: Conduct periodic quality audits to ensure compliance with industry standards and internal procedures.

7. Corrective and Preventive Actions (CAPA): Implement CAPA to address identified issues and prevent recurrence.

8. Documentation and Traceability: Maintain comprehensive records of all quality checks, test results, and corrective actions to ensure traceability and accountability.

Implementing these methods ensures high-quality metal products and compliance with industry standards.
