PURPOSE:To clearly and easily decide the penetration state of muddy water containing salinity by cutting a closed structure component and exposing a reagent which reacts to the salinity to change color to its inside. CONSTITUTION:The closed structure component 11 into which the muddy water containing the salinity is considered to have penetrated is fused with a gas burner and a solution 15 of 1% silver nitrate as the reagent which changes color by reacting to the salinity is atomized on the internal surface 12 of the component from an atomizer 16. If the muddy water 14 contains salinity, the solution changes into white drops 17 of water. Thus, the salinity penetration state of a suspension arm, etc., is easily decided and clearly and even if soot sticks in the cutting operation, it causes no trouble, so the component can be cut in a short time with the gas burner. |
