摘要

摘要明确了1.2 GPa超高强度钢板短时间大电流点焊的任务。开发了大电流短时间点焊系统和高频电源。为了防止飞溅,提出了一次通电、冷却和二次通电的新型双脉冲焊接方法。采用这种新型焊接方法,熔核直径和抗拉剪切强度均满足目标要求,且未发生飞溅。建立了1.2 GPa超高强度钢板短时间大电流点焊新方法。关键词:电阻点焊超高强度钢飞溅拉伸剪切强度资助本研究由新能源和工业技术发展组织(NEDO)在新能源和工业技术发展组织(NEDO)先进材料结构材料研究所(ISMA)的主持下委托进行。

Short time resistance spot welding of 1.2Gpa ultra-high strength steel using high frequency power supply
AbstractThe task of 1.2 GPa ultra-high strength steel sheet in short time’s high current spot welding has been clarified. High current and short time spot welding system and high frequency power supply has been developed. In order to prevent spatter, new dual-pulse welding method in which primary energization, cooling and secondary energization has been proposed. By using this novel welding method, nugget diameter and tensile shear strength satisfied the target and spatter did not occur. New method of 1.2 GPa ultra-high strength steel sheet in short time and high current spot welding has been established.Keywords: Resistance spot weldingultra-high strength steelspattertensile shear strength Additional informationFundingThis research was commissioned by the New Energy and Industrial Technology Development Organization (NEDO) under the auspices of the Institute of Structural Materials for Advanced Materials (ISMA) of the New Energy and Industrial Technology Development Organization (NEDO).
