This paper introduces that the transverse rotating magnetic filed, of which excitation current and frequency can be altered respectively, is applied to the DCEN (direct current electrode positive) MAG industry welding with the shield gas of (Ar) 98%+ (O2 ) 2%. And its mechanism is researched carefully using high velocity camera.When fixing excitation frequency or excitation current, arc motion behavior, droplet transfer, wire melting coefficient and properties of welding materials are researched. Welding spatter results from arc luminous sphere bouncing up and down. We compared DCEN MAG industry welding with DCEP (direct current electrode negative) in order to further perfect rotating MAG industry welding.
