An NDT (Non-Destructive Testing) Welding Inspector is responsible for evaluating welds and materials using various testing methods without causing damage. They ensure welded structures meet industry standards, codes, and safety regulations by detecting defects such as cracks, porosity, or incomplete fusion. Common NDT techniques include ultrasonic testing (UT), radiographic testing (RT), magnetic particle testing (MT), and liquid penetrant testing (PT). These inspectors play a critical role in industries like construction, aerospace, oil and gas, and manufacturing. Their expertise helps maintain structural integrity, prevent failures, and improve overall safety.
