摘要
通过对热网管道的组对定位、打底层、填充层、盖面层、封底层焊接质量的控制 ,使焊缝的内在质量大大提高 ,降低了返修率 ,提高了工作效率 。
This paper puts forward several measures to improve the pipe welding quality in heating net implemen and they are to control the aligning of two pipes, foundation laying, filling, covering and closing. The practice shows that the welding quality has been greatly improved, the rate of redoing work has been reduced and the efficiency has been enhanced after taking these measures.
