Claims

[Scope of utility model registration request]

In a thermal spraying device that detonates a metal spray wire in the atmosphere or under reduced pressure using an impact large current discharge and sprays it on the inner surface of a pipe, the wire explosion spraying section is configured into a coaxial circuit with a reduced pressure container to form a low-inductance discharge circuit. and in the circuit there is a pipe, a perforated electrode coaxially arranged therein, and the outer conductor (container).
The spray wire is supported at the center of the pipe by a perforated electrode that is directly connected to the conductor pipe connected to the end.
A wire bomb spraying tool that sprays wire bombs onto a predetermined inner surface of a pipe using an axial drive mechanism while maintaining the center position of the pipe.
