本文介绍了对电站高压锅炉接管座角焊缝内部质量进行无损检测时适用的方法,指出合理选用检测方法是角焊缝检测质量的重要保证。重点论述了内径小于等于200mm大于等于84mm、壁厚为10 50mm全焊透熔化焊管座角焊缝超声波检测方法。
This paper introduces the applicable method for nondestructive testing of internal quality of fillet welds in power station high pressure boiler. It is pointed out that a reasonable selection of testing methods is an important guarantee for fillet weld inspection quality. Focus on the diameter of less than or equal to 200mm greater than or equal to 84mm, wall thickness of 10 50mm full penetration weld tube fillet welding ultrasonic testing method.
