影响闪光焊接头性能的最主要因素包括焊缝区域的温度场分布、闪光顶锻的工艺参数和焊缝区域出现的缺陷组织。焊缝区域的组织缺陷是前两者综合作用的结果。提高焊缝性能应当从温度场分布和顶锻工艺着手。
影響閃光銲接頭性能的最主要因素包括銲縫區域的溫度場分佈、閃光頂鍛的工藝參數和銲縫區域齣現的缺陷組織。銲縫區域的組織缺陷是前兩者綜閤作用的結果。提高銲縫性能應噹從溫度場分佈和頂鍛工藝著手。

The quality of the FBW joint is mainly decided by temperature field distribution, process parameters during upsetting and the structure defects. Structure defects are the result of integration of the two factors mentioned above. The performance of the weld would be improved with the regulation of the temperature field distribution and the upsetting parameters.
