One end 42 is a fulcrum and the other end 43 is a free end. Reference numeral 44 is a ball screw attached to the output shaft of the stepping motor 45. The ball screw 44 is screwed between the fulcrum of the arm 41 and the free end, and rotates the motor 45 to move the spray gun 3 up and down.

再開する。After a predetermined time has elapsed, the preheating / spraying switching signal is used to switch to the spraying mode, and the spray gun 3 is sprayed with aluminum powder. During thermal spraying, the rotational speed of the work 1 and the vertical movement speed of the thermal spray gun 3 are slower than during preheating. Each time the thermal spray gun moves up and down, the thermal spray film gradually increases in thickness. The control circuit 7 compares the film thickness detected by the displacement gauge 5 with a reference value to check the fluctuation of the thickness. Since the spray gun keeps the spray amount per unit time constant, in a normal case, the thickness of the spray film increases in proportion to time. When this proportional relationship no longer holds,
The control circuit 7 issues an alarm as if the nozzle of the spray gun is clogged. Here, the nozzle is cleaned and the thermal spraying is restarted.
このようにして溶射ガンが正常な状態で溶射を行い、ワ
