The quality of welding is an important factor that influences steel structure project quality. Nondestructive inspection is an important method which guarantees welding seam quality. From the view of interrelated standards points, the author introduces some usual methods for nondestructive inspection including ultrasonic inspection, ray inspection, magnetic particle inspection and penetrant inspection.
