| titleOfInvention | Etch solution composition for welding test |
| abstract | The present invention relates to an etchant composition for welding testing, comprising: an etchant composition used for a macrographic test of a weld in a cargo hold of an LNG carrier; The etching solution composition for a welding test, which is composed of hydrochloric acid: 18-22 ml, hydrogen peroxide: 32-48 ml, and ethanol 30-50 ml with respect to 100 ml of the etching liquid in total.n n n According to the present invention, it is possible to shorten the welding quality inspection time due to the fast reaction speed in the weld, and to obtain the effect of improving the accuracy of the inspection by obtaining a clear bead shape.n n n n Weld quality, weld beads, test, etchant, inspection, etchant composition |
