Application Of Process Audit In Excavator Fabrication Welding Manufacture

With the rapid development of Chinese economy in recent years, construction machinery also experienced a rapid development. Domestic excavator industry is everywhere, from scratch to achieve a rapid expansion, various brands together into battle, and foreign brands on sales, service and quality to compete against. But with the national economic restructuring, consumption, investment and net export growth has fallen to varying degrees, including real estate, mining and other projects using the large number of machinery industry is the rapid decline, to the engineering machinery development has brought great difficulties and challenge. Excavator industry is facing enormous challenges, since 2012, a sharp decline in sales,2012 sales fell 34% in 2013, down 3% in 2014, down 15%, to the first half of 2015 fell by 20.5%, total industry entered a new normal slow growth.Countries have developed "all the way along the" western development and urbanization in rural areas and other policies and bring opportunities for the development of the next excavator industry. Minicomputers, increasing demand for special order machine, high-quality products have become the basis of customer requirements. Continue to improve the quality of products, it is the focus of our production management personnel.Lean production methods as a tool of domestic construction machinery industry recently the main push, play a good role in promoting quality improvement, efficiency, and reduce costs. We put this tool in the field of application method and VDA6.3 review process implemented in conjunction scene, and explore more suitable process control and continuous improvement methods.In this paper, the first and second chapters of lean production methods and tools were introduced VDA6.3; third section with DLG company as the research object, introduced its quality control situation and the implementation of lean process audit conditions; chapter divided into four sections of the audit process audit of nineteen points are described; Chapter five points DLG company implemented in specific implementation of the application process.The purpose of this writing is the actual status of the company, through the introduction and implementation of utility methods, the formation of a suitable quality control of its own process, and ultimately achieve the purpose to enhance the company’s level of quality, and process engineering machinery manufacturing quality control for reference.
