【Abstract】 High quality signals are most essential in realizing the metal droplet transfer controlling in metal gas arc welding.On the basis of dynamic characteristics of the arc spectrum,arc spectrum signals of different metal transfer modes have been acquired by experiments.Compared with arc current voltage,and arc light intensity,arc spectrum signals could be considered the best metal transfer signal which has the advantages of multi transfer modes adaptability,high signal intensity and high ratio of signal to noise.更多还原
