Problems solved by technology

The automobile body-in-white, which is mainly composed of aluminum alloy extruded profiles, has the advantages of light weight and good mechanical properties. Aluminum alloy profiles are sensitive to temperature, easily deformed after welding, and the welding quality and dimensional accuracy are difficult to control. Existing body welding methods cannot effectively reduce the welding deformation of the body, and the welding quality and dimensional accuracy of the body cannot be guaranteed

Abstract

The invention discloses a welding method of a frame type aluminum alloy vehicle body assembly. The welding method of the frame type aluminum alloy vehicle body assembly comprises the following steps that firstly, a vehicle body sub-assembly is welded, and then an air chamber assembly, an upper vehicle body assembly and the vehicle body sub-assembly are welded; a left articulated junction plate anda right articulated junction plate are symmetrically welded to the vehicle body sub-assembly at the same time; a front coaming assembly and the vehicle body sub-assembly are welded; a brake pedal installation support is welded to the vehicle body sub-assembly; and a left front wheel cover reinforcing beam and a right front wheel cover reinforcing beam are symmetrically welded to the vehicle bodysub-assembly at the same time. According to the welding method, by means of the reasonable assembling and welding sequence, the size defects caused by welding deformation are effectively reduced, andthe dimensional precision of the vehicle body assembly is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a welding method for a frame-type aluminum alloy body assembly. Background technique [0002] With the increase in the number of cars and the strict requirements of environmental protection regulations, the problems of environmental protection, energy saving and emission reduction have become more and more prominent, so it is imperative to reduce the weight of the car body. The lightweight of the car body aims to reduce the weight of the car body on the basis of ensuring the safety, crashworthiness, torsion resistance and handling of the car. In view of the advantages of small specific gravity, high strength, good formability and low cost of aluminum alloy materials, aluminum alloy materials are widely used in the manufacture of automobile bodies. The automobile body-in-white, which is mainly composed of aluminum alloy extruded profiles, has the advantages of light...
