压力容器焊接质量控制的研究与实践

从保证压力容器制造质量的关键环节——焊接着手,经过长期研究与实践,提出了影响压力容器焊接质量五个方面的主要因素,即:操作人员因素、机器设备因素、原材料因素、工艺方法因素、环境因素,简称"人、机、料、法、环"。通过对上述五因素的分析,提出了压力容器焊接质量分析因果图,按照该因果图,在压力容器制造的实践中取得了良好的效果,其理念和指导思想在压力容器制造行业中具有一定的推广应用价值,对提高我国压力容器制造质量,特别是对焊接质量控制具有一定的指导作用。

Research and practice of quality control for pressure vessel welding

Enter on the welding that is the key process to ensure the quality of the pressure vessel manufacture,after a long research and practice,the paper indicates five main factors effected pressure vessel welding quality,namely the operator factors,equipment factors,raw materials factors,process factors,environmental factors.Through analysis of above mentioned five factors,analysis causal diagram of pressure vessel welded quality is gained.According to the this diagram in the pressure vessel manufacturing practice,achieves good results.Therefore,this conception and guiding principle has some promotional value in the pressure vessel manufacturing industry.As well as it can improve the manufacturing quality of pressure vessel,especially has a guiding role in welding quality control.
