摘要：
The aim of this study is to obtain fundamental knowledge about the weld pool oscillation behaviour during GTA welding of mild steel and austenitic stainless steel under various conditions and to explore the possibility of using this oscillation behaviour as a means of sensing the weld pool geometry. The weld pool is excited into oscillation by short current pulses of rectangular shape and the oscillation frequency is measured by analysing the arc voltage signal, which is directly related to the weld pool oscillation. The oscillation behaviour, oscillation mode and oscillation amplitude are also directly observed with the help of high-speed moving pictures.
