【摘要】：随着社会的发展,钢结构件的使用越来越广泛,其中钢结构零部件的焊接工序是钢结构零部件加工制作中一种特殊而且非常重要的工序。在这道工序中不可避免地会出现变形或焊接缺陷等类似的质量问题,如果操作者不注意加以控制,这种缺陷效应就会在整个焊接部件中放大,导致零部件质量不过关、损坏甚至导致严重的安全事故。因此建立建全原材料的供应质量控制体系以及建立焊前准备、组装、拼装、焊接、焊后处理和成品检验等全过程的焊接质量控制体系显得尤为重要。本论文针对集装箱钢结构焊接总线质量问题进行分析与研究。首先,介绍了研究背景和我国集装箱钢结构制造业的质量管理实际状况。其次,将企业质量管理与控制的现状从产品的质量管理流程、不合格品处理流程、质量信息控制流程等几个方面对其进行了介绍。然后,运用统计技术分析法对集装箱钢结构焊接的质量问题进行全面的分析,研究出人的因素、机器因素、环境因素为钢结构焊接质量的主要影响因素,运用六西格玛方法对集装箱钢结构焊接质量方面主要影响因素的问题进行改善。最后,运用有限元技术对集装箱钢结构质量改善效果进行验证,成效明显。
[Abstract]:With the development of society, steel structure is used more and more widely. The welding process of steel structure parts is a special and very important process in the processing and manufacture of steel structure parts. In this process, there will inevitably be similar quality problems such as deformation or welding defects. If the operator does not pay attention to the control, this defect effect will be amplified in the whole welding parts, resulting in parts of poor quality. The damage may even lead to serious safety accidents. Therefore, establish a quality control system for the supply of all raw materials and establish pre-welding preparation, assembly, assembly, welding. The welding quality control system of the whole process such as welding post-processing and finished product inspection is particularly important. This paper analyzes and studies the welding bus quality of container steel structure. First of all. This paper introduces the background of the research and the actual situation of quality management in China's container steel structure manufacturing industry. Secondly, the status of enterprise quality management and control from the product quality management process, non-qualified product processing process. The quality information control flow and other aspects are introduced. Then, the quality problems of container steel structure welding are analyzed by statistical analysis method, and the human factors and machine factors are studied. Environmental factors are the main factors affecting the welding quality of steel structure. The six Sigma method is used to improve the main factors affecting the welding quality of container steel structure. Finally. Finite element technique is used to verify the effect of improving the quality of container steel structure.
