熔焊工艺，如电阻焊和激光焊，在焊接异种材料的薄层时面临困难。超声波焊接通过使用高频振动和压力将能量输入到受影响的区域来创建固态焊缝，从而克服了许多这些困难。本文对薄板超声焊接的工艺鲁棒性进行了研究。通过力学试验对焊接接头的质量进行评价，并应用质量准则对焊接接头的可焊性进行评价。这些结果用于确定最佳焊接参数和鲁棒工作范围。(c) 2011年cirp。
Fusion welding processes, such as resistance welding and laser welding, face difficulties in welding thin layers of dissimilar materials. Ultrasonic welding overcomes many of these difficulties by using high frequency vibration and pressure to input energy into the affected area to create a solid state weld. This paper presents a process robustness study of ultrasonic welding of thin metal sheets. Quality of the welded joints is evaluated based on mechanical tests and the quality criterion is then applied to evaluate the weldability. These results were used to determine both the optimal weld parameters and the robust operating range. (C) 2011 CIRP.
