WebMeasurement and inspection after welding should check both the surface and inside of welds. The inside of welds is generally checked using ultrasonic waves or radiation beams. The surfaces of welds are checked using magnetic particles (magnetic particle testing: MT) or special liquids (penetrant testing: PT). In FA, where both the speed and ... WebOtherwise, destructive tests are the only sure way to determine weld serviceability. Radiographic Inspection. Radiography (X-ray) is one of the most important, versatile and widely accepted of all the nondestructive examination methods - Fig. 1. X-ray is used to determine internal soundness of the welds.
