摘要：【中文】本发明涉及一种汽车A柱制作方法，属于汽车车身结构设计技术领域。所述汽车A柱包括骨架，骨架边缘设有U型卡槽，骨架中间安装有透明玻璃材料，骨架与透明玻璃材料之间采用环形卡槽连接；所述骨架分为汽车A柱内部分和汽车A柱外部分，汽车A柱内部分和汽车A柱外部分采用等离子电弧焊的方法焊接为一体。本发明采用铝合金材料在满足汽车A柱的强度条件下，可以减轻重量；汽车A柱的两部分采用等离子电弧焊接技术可以达到一面焊接两面成型的效果，较现在常用的电阻焊焊缝美观、焊接效果好。本发明中的透明玻璃材料选用偏光镜，有效的减小了汽车A柱造成的视野盲区，同时在直线行驶中不干扰视线，提高了驾驶安全。 【EN】The invention relates to a manufacturing method of an automobile A column, and belongs to the technical field of automobile body structure design. The automobile A column comprises a framework, a U-shaped clamping 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 comprises an automobile A-column inner part and an automobile A-column outer part, and the automobile A-column inner part and the automobile A-column outer part are welded into a whole by a plasma arc welding method. The invention adopts the aluminum alloy material, and can reduce the weight under the condition of meeting the strength condition of the A column of the automobile; the plasma arc welding technology is adopted for the two parts of the automobile A column, so that the effect of forming two surfaces by welding one surface can be achieved, and compared with the existing common resistance welding technology, the plasma arc welding technology is attractive in welding line and good in welding effect. The transparent glass material in the invention adopts the polarizer, thereby effectively reducing the visual field blind area caused by the A column of the automobile, simultaneously not interfering the sight line in the straight line driving and improving the driving safety.
