Abstract

The invention belongs to the technical field of passenger car manufacturing, and relates to a welding process of a lightweight new energy all-aluminum passenger car. The all-aluminum passenger car includes a front wall, a rear wall, a left side wall, a right side wall, a ceiling framework, a chassis and a seat which are assembled in sequence. The chassis sequentially comprises a chassis front section, a chassis middle section and a chassis back section which are formed by welding aluminum alloy profiles, six stages are included during welding and include from wall welding, back wall welding, left side wall welding, side wall welding, ceiling framework welding and chassis welding, the entire welding process achieves the aims of controlling welding deformation, ensuring the overall quality of the all-aluminum passenger car and the car body strength by reasonably adjusting the welding process sequence and welding process parameters of the all-aluminum passenger car.

Description

technical field [0001] The invention belongs to the technical field of passenger car manufacturing and relates to a welding process for a lightweight new energy all-aluminum passenger car. Background technique [0002] According to the requirements of GB30510 "Fuel Consumption Limits for Heavy Commercial Vehicles", on May 26, 2015, the twelfth meeting of the third stage fuel consumption limit standards for heavy commercial vehicles initially proposed that in 2020, it will be reduced on the basis of the national standard in 2015. 20-25% target. [0003] Lightweight vehicles can reduce vehicle energy consumption and correspondingly reduce passenger car exhaust emissions, reduce air pollution, and at the same time improve vehicle handling stability, driving safety, ride comfort and other performance. Experiments have shown that if the weight of the vehicle is reduced by 10%, the fuel efficiency can be increased by 6% to 8%; for every 100 kg reduction in the curb weight of the ...
