Information × Registration Number 0203U008327, 0103U008456 , R & D reports Title The study of effect of high frequency currents on microplasma weldability of various metals and alloys, including aluminum. popup.stage_title Head Gvozdetsky Vasyl Stepanovych, Registration Date 30-10-2003 Organization E.O.Paton Electric Welding Institute of the National of Sciences of Ukraine popup.description2 The optimal currents modulation frequencies, providing maximal welding velocity, full weld penetration and high quality of welded joints are determined for microplasma welding of doped steels and alloys.The effect of various polarity impulses and current modulation frequency on oxide film destruction and addition element expulsion by microplasma welding of copper and its alloys is determined. The optimal modulation frequencies of various polarity current impulses and their effect on a quality of welded joints by high-speed microplasma welding of aluminum and its alloys are determined. A proposals on using of modulated high frequency current for high-speed welding of various metals and alloys, including aluminum are given.
