摘要
简要介绍了!10mm以下的小口径焊接钢管的直缝焊接生产工艺,高速焊接时阻抗器的安装方式。分析了传统工艺生产小口径焊接钢管时存在的问题和局限。通过改进阻抗器安装方式,小口径直缝焊接钢管的生产效率由过去的30m/min提高到60m/min,成材率由70%提到98%以上,效果明显。
Briefed in the paper are the straight welding process for small-sized steel welded pipes with O.D. under 10 mm and the installation method for the impedance device for hi-speed welding operation thereof. The problems and limitations related to the conventional processes for small-sized pipe production are analyzed, based on which, the impedance device has been modified, resulting in significantly heightening the productivity of the said small-sized straight welded pipe from 30 m/min, to 60 m/min, and the yield thereof from 70% to 98% or above.
