Analysis on Arc Physical Property of Two Kinds of 70kg Class Solid Welding Wire

The arc physical character of mixed gas arc welding with two kinds of 70kg class solid welding wire is analyzed by Analysator Hannover and high-speed camera,it is found that the major transitional form of two kinds of solid wire is short circuiting transfer.The diversity of welding procedure of two kinds of solid welding wire is analyzed by character of behavior of droplet,waveform of arc voltage and welding current and short-circuit period.And the component of surface of two kinds of solid wire is analyzed by auger electron spectrometer against the diversity of two kinds of solid wire on arc physical character and transitional form of droplet.
