The history of welding inspection is closely tied to the evolution of welding technology itself. In the early days of welding, visual inspection was the primary method of quality control. As welding became more sophisticated and critical applications emerged, the need for more advanced inspection techniques grew.

• Early 20th Century:
  • Welding began to replace riveting in shipbuilding and construction.
  • Visual inspection was the main method, relying on the experience and judgment of skilled inspectors.
• Mid-20th Century:
  • The development of non-destructive testing (NDT) methods such as radiography and ultrasonic testing revolutionized welding inspection.
  • Organizations like the American Welding Society (AWS) and the American Society for Nondestructive Testing (ASNT) were established to develop standards and certifications.
• Late 20th Century:
  • Computer-aided inspection techniques and automated NDT systems emerged.
  • Quality assurance programs became more formalized, with a greater emphasis on documentation and traceability.
• 21st Century:
  • Advanced NDT methods such as phased array ultrasonic testing and computed tomography are increasingly used.
  • The focus is on predictive maintenance and risk-based inspection to prevent failures before they occur.

Impact on Industries:

The evolution of welding inspection has had a profound impact on various industries, including:

• Aerospace: Ensuring the integrity of aircraft structures.
• Oil and Gas: Preventing pipeline failures and ensuring the safety of offshore platforms.
