钢衬垫焊缝的超声波检测
Ultrasonic Testing of the Weld with the Steel Backing
摘 要
通过对钢衬垫的单面焊双面成形焊缝（包括管道对接环焊缝、T形和角接焊缝）的超声波检测时出现的真假反射回波信号进行分析，提出了判断真假回波信号的方法，对钢衬垫焊缝的超声波检测具有一定的指导意义。

Abstract
In this paper, the true and false echo signals which appear in ultrasonic inspection of double-sided weld seams (including pipe butt girth weld, T-shape weld and angle weld) by welding from one-side are analyzed, and the causes and characteristics of the reflected echo signals are deduced. The method and technology of judging true and false echo signal are put forward, which has certain guiding significance for ultrasonic detection of weld seam with steel backing.
