特型接头对接焊缝的射线透照技术

Ray Technology in Butt Welding Seam of Special Type of Joint

对内燃锅炉和电站锅炉上的T型和角接两种特型接头对接焊缝,提出用适当的厚度补偿法克服RT厚度宽容度一般无法提高的固有缺点。本文概述此法原理、应用程序和效果及评价。可望为解决角接焊缝NDT难题提供有效手段。

The proper thickness compensation method in RT is proposed for inspecting the two special joints of butt-welds (ie T joint and corner Joint)involved in inner-burning boiler and power-plant boiler. It can overcome an inherent weakness of the limited thickness latitude in RT. Here is given an outline of this method and its application procedure, as well as its effect and evaluation. It may be expected as an effective manner for solving difficult key points in examination of fillet welds.
