北美的汽车工业界最近一直热烈讨论电容储能(CD)焊,主要原因是汽车轻量化的需求必须符合美国公司平均燃料经济性(CAFE)标准,结合强度碰撞测试的需要,导致在汽车制造上越来越多地采用热冲压硼钢。如图1和图2所示。这些钢往往难以有效进行电阻焊,因为其 The North American automotive industry has been intensely discussing capacitive energy storage (CD) soldering recently due to the need to reduce the weight of vehicles to meet the U.S. average fuel economy (CAFE) standard, which combined with the need for crash tests to result in a higher level of automotive manufacturing The more hot stamping boron steel. As shown in Figure 1 and Figure 2. These steels are often difficult to effectively resistance-weld because of them
