Title: Arc welding method
Inventor: HANEDA MITSUAKI
IPC: B23K9/12
Filed: 1982-02-10
Abstract: PURPOSE:To satisfactorily shift a droplet of a filler material to a molten pool, by generating an AC arc between a nonconsumable electrode and a material to be welded, feeding a filling material into the arc, alternately supplying electric power to the nonconsumable electrode and the material to be welded, and welding it. CONSTITUTION:An arc is generated between a nonconsumable electrode 2 and a material to be welded 3 by an electric power source 7 having an alternating current, and a filler material 4 is fed into its arc. In case of supplying electric power to the filler material 4, a current flows to the nonconsumable electrode 2 from the filler material 4, by connecting the positive pole of a DC electric power source 5, and connecting the negative pole of the DC electric power source 5 when the nonconsumable electrode 2 is a negative pole (positive pole arc). Also, when the nonconsumable electrode 2 is a positive pole (opposite polarity arc), a current flow to the material to be welded 3 from the filler material 4 by connecting the negative pole of the DC electric power source 5 to the material to be welded 3. In this way, no spatter is generated, a current load to a plasma torch is reduced, and the melting efficiency of the material to be welded 3 is improved.
