- 摘要:
- 介绍管道内焊机的结构、配套设备及在大口径厚壁管道施工中的独到优点。由于采用气体保护焊工艺和双面V型坡口,在管内对管缝进行第一遍焊接,保证了根焊道的质量,完全克服了单面焊接易产生缺陷的施工难题.
The paper introduced pipe internal welding machine's composition,necessary equipment and unique advantage in large diameter thick wall pipe construction. lt can guarantee root welding bead quality so as to overcome one side welding defects by using double V groove & gas-shielded arc welding process and welding first bead in the pipe internal side.2000,6(6): 39-40 收稿日期：2000-3-17
