[0024] Figure 1 The workpiece shown includes three parallel pipes of different lengths, namely the first vertical pipe 11, the second vertical pipe 12 and the third vertical pipe 13. The first oblique pipe 14 is welded between the ends of the first vertical pipe 11 and the third vertical pipe 13, and the second oblique pipe 15 is welded between the ends of the second vertical pipe 12.
