ABSTRACT

The topic for the current unreasonable layout of the vehicle's fuel tank production, low production efficiency, product qualification rate is not high time the issue in the full understanding and knowledge requirements of the vehicle's fuel tank manufacturing technology on the basis of investigations at home and abroad to collect the vehicle's fuel tank manufacturing enterprises the status quo , The analysis of low production efficiency, product is not a passing rate of the reasons for the high, propose solutions, in particular the welding method, filled with metal, welding technology and other factors on the effects of welding process, the better to optimize the welding process.
Through the fuel tank material, used welding method for welding materials and welding process of welding the tank for analysis, and the fuel tank under the actual conditions of work, welding method ultimately selected for resistance welding, flame brazing and CO2 arc welding.
The vehicle's fuel tank materials determine the circumstances, in accordance with actual conditions, to optimize the fuel tank welding, making the vehicle's fuel tank production layout more rational, efficient production must be increased, the product has also been a passing rate of increase, the tightness, strength and toughness are is improved.


Key words: Fuel tank, resistance welding, CO2 welding, flame brazing
