Zusammenfassung:	PURPOSE:To reduce a deposition loss, to form a sound weld bead with satisfactory workability and to perform welding free from defects by adding a magnetic field of ultrasonic frequency in the coaxial direction to the welding wire tip to perform welding. CONSTITUTION:In the ultrasonic vibration arc welding method, the ultrasonic vibration is added electromagnetically to an arc 6 of the welding wire 3 tip fed continuously and metal molten by arc heat generated between base metals 4 and a welding wire 3 is made into fine globules and transferred to the base metals 4. Accordingly, the generation of spatters is prevented and satisfactory welding is performed and the deposition loss is obviated and the sound weld bead is formed.
