Study On Body In White Welding Jig Dowel Pin Quality Management

With the advancement of science and technology in recent years,the automotive industry has also entered the fast track of development,which has become one of the representative industries with good development in our country.In domestic economic development,the automotive industry as a dominant industry comprises an important part,which is also a leading industry.The automotive industry does not only promote the formation of industrial clusters,but also stimulate the link between the construction market and the development of the steel mills and other production investment.At the same time,it is conducive to deepen the further development of electric power,transportation and other related industries.However,the quality of automobile is not always satisfying.The recall of automobile products events happen from time to time due to the quality problems,which cause a widespread social concern.Among them,the welding quality of body-in-white occupies the important position in the overall quality of the car,and the welding jig dowel is the key to determining the quality of body-in-white welding.The study of this article is about the body-in-white welding jig dowel quality management,which make clear in this article is elaborating the research background and significance,and summarize the domestic and foreign research status about quality control of the body-in-white,and introduce the research methods and research content.First,the article analyzes the factors affecting the quality of body-in-white,which mainly include personnel,welding process,welding jig,dowel,quality of stamping parts,welding equipment and welding quality,welding technology and process parameters,quality control and improvement,defect treatment.Second,the article discusses the welding jig and the positioning pin quality management,and discusses the control and management of welding jig.It expounds the influences of the precision of welding fixture of body-in-white,and introduces the basic structure of welding jig,design method,the depth of daily maintenance and maintenance management and other content;The article points out that the dowel standardization management measures are pushing dowel standardization work and strengthening the dowel pin material management.Third,the article studies and puts forward the standardized management of the body-in-white positioning pin,which needs everybody to participate the quality management of locating pin,which including fine management of welding jig,material inspection,welding process control,function size optimization.Through this article research,it can provide certain reference to the quality of the body-in-white welding jig dowel pin management.
