Welding Inspection and Testing Techniques

• Weld ability and welding electrodes .
• Physics of welding.
• Metallurgy of weld metal and heat affected zone.
• Failures of Welding.
• Welding defects (discontinuities.(
• Inspection of Welding :

– Visual inspection.                       ــ  Radiographic inspection.

– Liquid Pen errant inspection.      ــ  Magnetic Particle inspection.

– Ultrasonic weld inspection.        ــ  Eddy current testing.

– Mechanical testing (tensile strength, bend test, fatigue strength, and fracture toughness.(

• Welding codes, standards and specifications.
• Quality control of welded components.
• Quality assurance of welds as applied in ASME code, and other code.
• Welding validation, qualification and certification.
• ISO 9000 for quality assurance, overview.
• Case study.
