在管道铺设或大型梁架焊接过程中，往往会遇到两个或多个不同轴线的大直径管件相交的情况。工程上，为了管件的相交处焊缝均匀，焊接可靠，需要将相交管件的焊缝处准确切割成型。由于相交管件的直径变化，位置及方向的不同，其焊缝的形状也不相同。因而需要根据具体的相交情况，作出管件接缝处的展开曲线，按曲线制作样板，按样板切割成型，应用ＣＡＤ手段，可以方便快捷地解决这一问题。
In the pipe laying or large beam welding process, often encounter two or more large diameter pipe with different axes intersect. Engineering, in order to intersect the pipe fittings weld evenly, reliable welding, the need to intersect the pipe weld accurately cut shape. Due to the intersecting pipe diameter changes, the location and direction of the different, the shape of the weld is not the same. Therefore, it is necessary to make the expansion curve of the joint of the pipe fittings according to the concrete intersection situation, and to make the model according to the curve and to cut the model according to the model. The application of CAD means can solve this problem conveniently and quickly.
