摘要:
为了解决螺旋埋弧焊管焊冲合格率偏低的问题,采用统计分析方法对焊管焊冲单值和平均值进行了合格率计算,借助工序能力和工序能力指数评价体系,分析了产品质量及工艺水平,找到可能存在的问题,并给出相应控制措施。分析结果表明,A厂和B厂的工序能力指数评价为四级,C厂为三级;A厂和B厂的工序能力严重不足,可根据技术条件要求采取更改设计或适当放宽规格下限要求予以解决;C厂的工序能力也存在不足,应通过提高设备精度、改进工艺方法、提高操作技术水平、改善技术管理能力以及改善原材料质量等措施提高工序能力,加强检验或必要时全检,提高产品质量水平。
Abstract:
In order to solve the problem of low pass rate of weld impact energy of spiral submerged arc welding pipe, the single value and average value of weld impact work of welded pipe were calculated by statistical analysis method. The process capability and process capability index were resorted to evaluate the product quality and process level, find out the possible problems and put forward reasonable opinions. The results showed that the process capability index of A and B factories were level 4, and the C factory was level 3. For the A and B factories, the production line process capacity was seriously insufficient, it could be solved by changing the design and adjusting the requirements on the basis of technical requirements. For the C factory, the production line process ability was insufficient, it should be adopted to improve the precision of equipment, process methods, operating technique level, technology management capacity and quality of raw materials to enhance process capability, strengthen inspection and usefull inspection when necessary to improve the level of product quality.
