PROBLEM TO BE SOLVED: To provide an arc thermal spraying device capable of stably maintaining arc to realize stable operation, and efficiently atomizing a wire for thermal spraying. SOLUTION: The wires 11A and 11B for thermal spraying are fed toward a target point C while guided by two wire guide pipes 5A and 5B, and tips of the wires 11A and 11B are brought into contact with each other to generate arc. A merging point A of the primary gas flow is set close to the target point C, the beam-like primary gas flow flowing toward the merging point A along the direction inclined to the axis of thermal spraying from an area outside an area in which two wire guide pipes 5A and 5B are disposed is generated, and molten metal is atomized by blowing this primary gas flow to a molten portion of the tips of the wires. |
