如果将对焊接头取代于横梁、底座和管道的凸缘和搭接接头以及其他车身上结构件的焊接,能节省多少材料、重量和燃料?当粘合车门钣金件和汽车框架的密封胶水重量包含在总重量中,这个问题就非常值得一提。而这个问题取决于零部件。如果不再使用凸缘搭接,减少的重量能高达几公斤,同时也能节省每部分的安装空间,约高达8～16mm。搭接凸缘设计是两项极具现代车身制造特色的发明逐渐成熟的产物。第一项是诞生于1877年的电阻焊,它是快速、高效和实用的焊接加工方法。第二项是1 954年应
How much material, weight, and fuel savings can be achieved if the butt-welded joint is replaced by the welding of the flanges and lap joints of the base and pipe, and the structural members on other bodies? When the glue that joins the door sheet metal to the car frame The weight is included in the total weight, this question is very worth mentioning. And the problem depends on the parts. If you no longer use the flange lap, the weight can be reduced up to a few kilograms, but also can save each part of the installation space, up to about 8 ~ 16mm. Overlap flange design is the result of the invention of two very modern body features mature. The first is resistance welding, which was born in 1877 and is a fast, efficient and practical method of welding. The second one should be 1954
