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.溶接用備品及び溶接操作の際にUV放射曝露を検出するためのシステムが開示される。前記溶接用備品は電気溶接アークにより生成されるUV放射へ曝露される表面を有し、UV放射への曝露がない場合の第1のイメージと、電気溶接アークにより生成されるUV放射への曝露の後にのみ可視的となるUV活性化色素から形成される第2のイメージを含む。システムは、第1の状態と少なくとも第2の状態を持つUV曝露インジケータを含み、UV放射への曝露を可逆的に又は可視的に示し続けるように適合されるUV活性化色素を含む。可視的に示すことには、シンボル、ロゴ、イメージ、テキスト又は他の装飾的又は情報的デザインを望むように組み合わせることを含む。
