The welding arc clothing which have ULTRAVIOLET RADIATION activation image and the method of detecting ULTRAVIOLET RADIATION emission

摘要

The system in order to detect ULTRAVIOLET RADIATION emission disclosure the case of the fixture and welding operation for welding is disclosed. The fixture for the aforementioned welding is disclosed has the surface which to the ULTRAVIOLET RADIATION emission which is formed by the electric welding arc includes the 2nd image which is formed from the ULTRAVIOLET RADIATION activated pigment which becomes visible only after the disclosure to the ULTRAVIOLET RADIATION emission which is formed by the 1st image and the electric welding arc when there is no disclosure to ULTRAVIOLET RADIATION emission. The system 1st state includes the ULTRAVIOLET RADIATION being disclosed indicator which at least has 2nd state, in order disclosure to ULTRAVIOLET RADIATION emission or to continue to show visibly reversible, includes the ULTRAVIOLET RADIATION activated pigment which conforms. In order symbol, logograph, image, text or other decoration or to desire information design, the fact that it combines is included to the fact that it shows visibly.
