The invention provides an automatic welding process for a vehicle body side beam assembly. The automatic welding process comprises the following steps of assembling a vehicle body A column of the vehicle body side beam assembly and each component thereof and welding to form an A column assembly; welding the first end of the welded A column assembly to the end of the first end of a side beam fitting in an anti-deformation welding mode, and specifically, deflecting the second end of the A column assembly to a preset angle away from the second end of the side beam fitting during assembling and positioning before welding; and welding a reinforced inclined beam in front of a threshold between the A column assembly and the side beam fitting to play the role of reinforcing bars. In the automaticwelding process for the vehicle body side beam assembly, the welding deformation is effectively reduced and the dimensional accuracy is improved by reasonably controlling the welding sequence betweenthe A column assembly, the side beam fitting and the reinforced inclined beam in front of the threshold; the first end of the A column assembly is welded to the end of the first end of the side beam fitting in the anti-deformation welding mode, so that the welding deformation of the A column assembly is canceled, and the size of the vehicle body side beam assembly is conductive to controlling.
Description
technical field [0001] The invention relates to the technical field of welding technology, in particular to an automatic welding technology for a vehicle body side beam assembly. Background technique [0002] The body structure in the traditional automobile field is made of steel. Although the cost is low, the overall weight is large, there are many types of parts, and the process is complicated. The lightweight development of the body is restricted, which is not conducive to energy conservation. [0003] With the increasing popularity of electric vehicles, the application of aluminum alloy materials in body manufacturing is becoming more and more extensive, which not only greatly reduces the weight of the vehicle, but also greatly improves the performance of the body. [0004] As an important part of the vehicle body, the side beam assembly of the vehicle body plays an important role in the production quality of the side beam assembly to the overall quality of the vehicle b...
