T型焊缝半熔透超声检测

Ultrasonic Testing of Incomplete Penetrated Welds in T-weld Joints

本文介绍了用直探头在翼板上或短前沿探头在腹板上探测T型焊缝未熔透区尺寸,然后根据实际焊板上熔透区尺寸来制定检测方法,检测熔透区缺陷,未熔透区不再检测范围之内,从而讨论其可行性。

This article describes detect incomplete penetration weld of t-joint by use of a straight probe on the flange or a short leading edge probe on the web,and then develop a test method based on the actual penetration area of the weld plate to detect penetration.Zone defects,unpermeated zones are no longer within the scope of detection,thus discussing their feasibility.
