The impact values at two vibratory accelerations ( 0.3g and 0.6g ) are compared and the changing mechanism is discussed . The internal friction test indicates that the internal friction SKK ( Snoek-Ke-Koster ) peak of the weld metal has good correlation with the impact value of the weld .
通过对两种振动加速度（0.3g和0.6g）下焊缝冲击性能的对比，讨论了冲击性能变化的机理，并用内耗试验说明焊缝金属内耗的SKK（Snoek-Ke-Koster）峰值与焊缝冲击韧度存在良好的对应关系。
