随着焊接事业的发展,对焊缝及坡口的要求亦愈趋提高。因此,在实际生产中,对它们的尺寸要进行测量和检验。焊缝及坡口测量卡板则是一种携带方便,使用便利,具有一定精度,适用性较广的测量工具。该卡板是由呈多角形的卡板、中间带有长形孔的滑尺、斜形尺和弹簧片、铆钉所组成(图1)。滑尺和斜形尺都是经由弹簧片、铆 With the development of the welding business, the requirements for welds and bevels have also been on the rise. Therefore, in actual production, their size should be measured and tested. Weld and groove measuring card board is a portable, easy to use, with a certain accuracy, wide applicability of the measuring tools. The card board is a polygonal card board, with a long hole in the middle of the slider, oblique feet and spring pieces, rivets (Figure 1). Slide and oblique feet are through the spring, riveting
