The effect of welding currents and welding speed on bead appearance and shape of triple-electrode high speed CO2 fillet welding on double sides was investigated. It was found that the current of leading electrode should be the highest,and current difference between leading electrode and middle electrode had better be 100A or above to obtain good weld quality. The current difference between middle electrode and trailing electrode don't play an obvious role in weld quality,and the electrode… CONTINUE READING
