通过统计发现焊接气孔是化工管道安装焊接中最容易出现的缺陷,通过对气孔产生原因的分析,提出了化工管道安装中预防气孔的措施,并对化工管道焊接后出现的气孔处理方法进行了探讨。 Through statistical analysis, it is found that the weld porosity is the most prone defect in the chemical pipeline installation and welding. Through the analysis of the causes of the pore, the measures to prevent the pore in the chemical pipeline installation are put forward, and the stomatal treatment method after the chemical pipeline welding is discussed .
