Ultrasonic Tester (UT) is commonly used in pipe welding industry for pipe body material defect check and weld seam defect check 2 major types of UT are mostly used for both spiral welded pipe mills and ERW pipe mills
No matter it's online or offline Ultrasonic Testers, they consist of the mechanical system and the ultrasonic test system.
The ultra-sonic test system is the core to perform the test. It transmits ultrasonic wave to the test object and receives the return wave to detect the defects of the material.
