Abstract: Based on the analyses of the motion mechanism of welding arc in longitudinal magnetic field, the conception of accompanied magnetic field with spiral pipe shape was put forward, and its forming principle was studied. The internal relation between the contracted effect of bell shade shape welding arc and the accompanied magnetic field with spiral pipe shape was also discussed. The attached magnetic field with spiral pipe and the contracted phenomenon of welding arc with bell shade shape were proved.
