| Abstract: | 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.$$$$ |
