摘　　要：利用熔池振荡及熔池谐振信号的检测 ,以熔池自身固有振荡频率与熔池尺寸的内在关系测定熔池金属表面张力 ,研究了薄板SUS30 4不锈钢TIG焊不同熔池尺寸的表面张力变化以及活性剂对熔池表面张力的影响。By detecting the signals of weld pool oscillation and weld pool resonance, the weld pool surface tension is measured in this paper based on the intrinsic relationship between weld pool oscillation frequency and weld pool size. The surface tension variation of weld pool with different size and the effect of active flux on surface tension of weld pool are studied during TIG welding of thin stainless steel SUS304. The experimental method is the preliminary application for surface tension detection of weld pool.$$$$
