Aluminum has become the preferred material in the era of automotive lightweight
Release time:
2022-07-29
【Summary Description】 With the increasing calls for environmental protection, consumption reduction and emission reduction in China, automobile lightweight has become the general trend, and with the increasing technical difficulty of engine research and development, whether it is fuel vehicles or new energy vehicles, lightweight is imperative. Big data shows that using aluminum instead of steel can reduce the weight of the whole vehicle by 30%-40%, the engine can reduce the weight by 30%, the radiator can reduce the weight by 20%-40% compared with copper, and the body can reduce the weight by more than 40%. From this point of view, aluminum instead of steel, weight reduction effect is remarkable. In contrast, the aluminum body structure is lighter and stronger. Audi, Weilai, etc. have used all-aluminum body structures, and aluminum alloys are also widely used in aerospace, automobiles, machinery, ships, and chemicals due to a variety of excellent properties. And other fields. Today, I will mainly talk about the welding of automobile air conditioning condensers, evaporators, water tank radiators, oil coolers and other components. Current aluminum alloy brazing methods include flame brazing, furnace brazing, inert gas brazing, vacuum brazing, and induction brazing. In the increasingly severe situation of industrial upgrading and environmental protection, it is difficult to introduce high-skilled flame brazing talents, so induction brazing has become a very suitable welding method, and induction brazing has no open flame, less investment in process funds, and high welding efficiency., Low labor dependence and high degree of equipment automation are widely used in the welding of automotive aluminum materials. The advantages of improving product welding quality, saving costs and efficiency have become the only choice for major companies. Induction Brazing Equipment
