预应力钢筒混凝土复合管自动焊接系统的研制

Study of automatic welding system of pre- stressed steel- concrete compound pipe

介绍了超薄壁 ,大直径 ,长筒体 ,纵、环缝自动焊接系统的结构、组成、工作原理及设计的主要特点。该系统已成功地应用于直径 140 0 mm ,筒身长 50 0 0 mm ,壁厚 1.5mm的钢筒的自动焊接生产中。生产实践证明 :该自动焊接系统对预应力钢筒混凝土管的焊接取得了良好的效果 ,是一种新型的低成本自动化大直径超薄壁长筒体纵、环缝自动焊接通用设备。

The structure,constitute,working principle,and design feature of automatic welding system which pro- duces extra- thin,large diameter,long tube,and longitudinally or circle weld are introduced.The system is used successfully in automatic welding of steel tube( φ=140 0 ,L=50 0 0 mm,δ=1.5mm) .Itis proved the au- tomatic welding system is suitable for welding pre- stressed steel- concrete compound pipe,and is a new low cost,automatic welding equipment for longitudinally or circle weld of extra- thin,large diameter,long tube.
