Fast-convert ultrasonic frequency pulse GTAW arc behavior

  • 摘要: 基于超音频直流脉冲钨极氩弧焊(GTAW,Gas Tungsten Arc Welding)电源输出脉冲电流沿变化率di/dt≥50A/μs的超音频直流脉冲方波电流,将其用于0Cr18Ni9Ti奥氏体不锈钢GTAW焊接过程,研究分析了焊接电弧特性、电弧力及焊缝熔透特性.结果表明:超音频直流脉冲方波电流参数对电弧电学特性、形态及电弧力产生显著影响,与常规直流GTAW相比,快变换超音频直流脉冲GTAW电弧表现出明显的收缩效应,焊缝熔深在一定范围增大,熔宽减小,平均电弧力大幅增长,焊接效率提高.
