Automobile A-pillar manufacturing method

The invention relates to an automobile A-pillar manufacturing method, and belongs to the technical field of automobile body structure design. The automobile A-pillar comprises a framework, a U-shapedclamping groove is formed in the edge of the framework, a transparent glass material is installed in the middle of the framework, and the framework is connected with the transparent glass material through an annular clamping groove. The framework is divided into an automobile A-pillar inner part and an automobile A-pillar outer part, and the automobile A-pillar inner part and the automobile A-pillar outer part are welded into a whole through a plasma arc welding method. An aluminum alloy material is adopted, so that the weight can be reduced under the condition that the strength of the automobile A-pillar is met. The two parts of the automobile A-pillar can achieve the effect of one-side welding and two-side forming through the plasma arc welding technology, and compared with existing common electric resistance welding, the welding seam is attractive, and the welding effect is good. A polariscope is selected as the transparent glass material, the view blind area caused by the automobile A-pillar is effectively reduced, meanwhile, the sight is not disturbed in the linear driving process, and the driving safety is improved.
