SAE/USCAR-45定义了汽车用超声波焊接线对线接头的试验方法和性能要求。可以测试图1所示的面对面、对接接头和中心条配置。本规范中定义的试验使试验样品承受模拟道路车辆暴露寿命的应力。本规范中要求的应力包括热冲击、温度/湿度循环和来自不同方向的机械应力。

SAE/USCAR-45 defines test methods and performance requirements for ultrasonically-welded wire-to-wire splices for automotive applications. Face-to-face, butt splice, and center strip configurations per Figure 1 can be tested. The tests defined in this specification subject samples on test to stresses that simulate a lifetime of exposure for a road vehicle. Stresses called out in this specification include thermal shock, temperature/humidity cycling and mechanical stress from different directions.
