3·The joint which is connected by welding method is called the welding joint, which is composed of welding seam, fusion zone, heat affected zone and its adjacent base metal.
用焊接方法连接的接头称为焊接接头，它由焊缝、熔合区、热影响区及其邻近的母材组成。
4·Welding seam should be numbered according to pipeline medium set, in principle, main pipe prior to branch pipe.
焊缝编号应根据管线介质流向进行编号，原则上应先主管后支管。
5·Welding seam tracking system with linear CCD intelligent image sensor is described.
叙述了一种基于线阵CCD摄像机为传感器的焊缝自动跟踪系统。
