The details will be described below. In FIG. 1, 1 is a jet nozzle, 2 is a supply nozzle, 3 is a combustion gas fire, 4 is an induction coil, 5 is a sprayed powder material, and 6 is plasma. Next, the operation of the present invention will be described. A combustion gas fire 3 is obtained by supplying combustion gas to a combustion gas injection nozzle 1 which is arranged on the left and right of the axis of the welding torch portion and is coaxially bored. Then, an alternating current is caused to flow through the induction coil 4 from a power supply device (not shown) to induce an alternating magnetic field in the combustion gas fire 3 to ionize the combustion gas and generate plasma 6. Next, the thermal spray powder material 5 is supplied into the combustion gas fire 3 from the supply nozzle 2 formed on the axis of the welding torch portion, and the thermal spray powder material 5 is melted, so that the sprayed material (not shown) is exposed to the combustion gas It is possible to spray the sprayed powder material sufficiently melted by the heat and the heat of the plasma.

In addition, the combustion of the gas causes a high-temperature fire gas, and the thermal spray powder material is also overheated, so that plasma is easily generated. Further, the heat of the combustion gas and the heat of the plasma can sufficiently melt the thermal spray powder material to form a strong thermal spray coating.
