説明
Metal transfer and arc characteristics in self shielded flux cored arc welding for mild steel and 50kgf/mm^2 class tensile steel were studied by using a high speed cine photographic technique. Basic type (included CaF_2) flux cored wire was used with electrode positive polarity. The following conclusions were obtained. The metal transfer mode in self shielded flux cored arc welding was classified into three types, Bridging Transfer Mode, Free Flight Transfer Mode and Bridging Transfer without Arc Interruption Mode. Bridging transfer mode operation resulted in good properties of the weld metal, while spattering occured and the spattered droplets were large. In the region of comparatively high arc voltage, the free flight transfer mode appeared, in which the size of spattered droplets were relatively small. In bridging transfer without arc interruption mode which was realized in the region of higher current and higher feeding rate of wire, the spattering were extremely reduced.
