Claim 8:
9. A gas leak inspection method performed using (i) a gas leak inspection device including (i.a) a gas sensor disposed outside of a hollow inspection target and facing an outer surface of the hollow inspection target and (i.a) an actuator that produces relative movement between the hollow inspection target and the gas sensor while the gas sensor faces the outer surface of the hollow inspection target, and (ii) an additional gas leak inspection device including an additional gas sensor and that covers a partial area of the outer surface of the hollow inspection target, the method comprising:
detecting, by the gas sensor, a gas that escapes the hollow inspection target;
producing, by the actuator, relative movement between the hollow inspection target and the gas sensor by rotating the hollow inspection target about an axis of the hollow inspection target, the gas sensor comprising a plurality of gas sensors spaced apart in a circumferential direction of the hollow inspection target and centered about the axis of the hollow inspection target; and
inspecting, using the additional gas leak inspection device, the partial area of the outer surface of the hollow inspection target for presence of a gas leak.
