ARC WELDING METHOD

PURPOSE:To execute arc welding with high performance, with high efficiency and at a low cost, by making a powder-particle-like flux adhere to th outside circumference of a welding wire by electrostatic attraction, supplying it to an arc generating part, and executing the welding. CONSTITUTION:A welding wire 1 is fed continuously in the direction of a base metal 3 through a guide 4 and an electrifying chip 5, also a flux F is supplied into a collecting box 6 by carrier gas from a feed pipe 8, and arc welding is executed. The flux F supplied to the collecting box 6 is impressed electrostatically by an electrostaic impressing part 10, and is collected in the lower part of the box 6 successively. There is a potential difference between the wire 1 passing through this box and the base metal 3, therefore, the flux F adheres almost uniformly to the outside circumference of the wire 1 by static electricity, and is supplied continuously together with the wire 1 in the direction of the base metal 3. In this way, gas is generated by welding heat of the flux F, also a slag is generated, and welding being same as a covered electrode is executed.
