The Technology And Quality Control Method Of One-side Spot Welding Bile Body

Resistance spot welding as an important branch of science and technology of welding,with the rapid development of automation and computer technology,the resistance spot welding technology has been rapid development.Because it is a simple,low cost,effective plate connection method,it is widely used in aerospace,energy,electronics,automobile and light industry.In recent years the rapid growth of automobile industry in our country,according to statistics,every car in car body,around 5000 resistance welding solder joints,has been widely used in the body welding.This paper studies the special form of single-side spot welding technique as normal pressure spot welding,which satisfies the principle of ordinary spot welding and has its own characteristics.The solder points of single spot welding welding are good surface quality at the non-electrode side of the non-electrode side.Single-sided spot welding as a giant,shells covering parts assembly a complementary process of spot welding process,it can avoid large electrode holder used parts and complete vehicle body some direct welding welding conditions.This paper body welding welding method used in common use is introduced,and the current situation of automobile body welding technology development,and to forecast the development trend of automobile body welding technology;Using production process a lot of practice to the body carries on the summary analysis of the characteristics and applications of the resistance spot welding,a comprehensive and systematic understanding and mastering the car body principle of spot welding,the welding process characteristics,the characteristics of welding equipment,welding defects,the main reasons for provide reference and help for resistance spot welding process using guidance.In this paper,the technical parameters of single-side spot welding technology are studied in the process of production process.The cause of the single spot welding quality defects in the process of production through continuous structure and welding technology parameters,tooling process factors such as adjust the research solution;With calderon iron roof single-sided spot robot welding system design as an example,the system of research design single-sided spot welding process,and the matters should be paid attention to the design process,and avoid body single-sided spot welding quality defects and faults in the application problems,improve body processing appearance quality and efficiency.
