Abstract
PURPOSE: To make the driving magnetic field generating device for magnetic-driven arc welding small-size to monitor the welding state, by arranging bar-form electromagnets in a specific direction between two magnetic plates in this magnetic field generating device.
CONSTITUTION: After tube bodies 1 and 2 to be welded are butted to each other with gap (g), magnetic field generating device 10 opened divisionally is arranged on the tube outside circumference near the surface to be fayed by welding, and a current is flowed to device 10 to generate a magnetic field in the radius direction in the space between matched tube bodies. Magnetic fields generated in tube bodies 1 and 2 go from the N pole of magnetic plates 6 and 8 toward S-pole magnetic plates 7 and 9, and magnetic force lines parallel with the axial line B-B of tube bodies 1 and 2 are formed. At this time, when a current is supplied from welding power source 16, arc 15 is ignited between surfaces to be fayed and is rotated and driven continuously along the tube circumference by the magnetic action of the arc current and the magnetic field according to the Fleming's left-hand rule; and when surfaces to be fayed reach a welding temperature, movable clamp 3 is moved forward to weld both tube bodies 1 and 2 by pressurizing.
