“…In view of the development of measurement techniques, it is now possible to try to determine the actinic radiant exposure from arc ignition and evaluate the actinic UV hazard and compare the results with those reported in the previous study of Eriksen [7]. Previous studies carried out by the present authors [23] indicated that the duration of UV radiation peak of arc ignition could be in the range from 20 ms-220 ms depending on the welding technique, and these results were consistent with the results obtained by Eriksen [7]. The estimated actinic irradiance during the ignition phase was 1.2-5-times bigger than the average actinic irradiance after ignition (maximum 26-times bigger for the worst case).…”

“…Previous studies [23] have focused on the evaluation of UVR hazard during the arc ignition phase in three welding processes: TIG, MAG, and MAG-P. The welding arc ignition phase was recorded with a photometer capable of performing sampling with a frequency of 50 Hz.…”

“…The estimated actinic irradiance during the ignition phase was 1.2-5-times bigger than the average actinic irradiance after ignition (maximum 26-times bigger for the worst case). It corresponded to actinic radiant exposure of 30 J/m 2 reached from 0.5 s-37.5 s under average conditions and 0.1 s for the worst case [23].…”

“…This poses a significant health risk to all workers present in the vicinity of the welding area [15,20]. Exposure to optical radiation when striking the arc could also pose hazard for the eyes of everybody present in the vicinity [7,9,14,22,23].…”

“…However, in the article from 1991, he wrote that the ignition phase of MIG/MAG welding arcs lasts approximately 25 ms [6]. It seems strange that in the period of about 30, except for one conference paper delivered in 2018 [23], there was no interest in this interesting phenomenon in relation to UV or blue light hazard evaluation (conclusion drawn from the overview of published studies and research reports). A few studies on optical hazard evaluation from arc welding report a high increase of optical radiation emission during arc ignition [8][9][10]12,14,15], but all of them relate to the results of Eriksen's study [7].…”

Welding arcs emit strong ultraviolet (UV) radiation, which could pose serious health risks for skin and eyes. According to Directive 2006/25/EC, UV hazard evaluation has to be performed in the working environment. The measurement of welding arc ignition radiation is a difficult task. This article describes the effort made to determine actinic radiant exposure levels during welding arc ignition in the controlled environment of a welding laboratory. A new method of UV actinic hazard evaluation from welding arc ignition radiation using a CCD spectroradiometer combined with a photometer is presented. The hazard of UV emitted in pulsed metal active gas welding (MAG-P) of construction steel is described. The duration of ignition peak in the study was in the range of 9–15 ms. The actinic radiant exposure during arc ignition over aversion response time was in the range of 0.26–1.12 J/m2. The daily exposure time can easily exceed the permissible exposure time obtained in our study, i.e., 13–34 s, which means that UV radiation form MAG-P arc welding is hazardous for workers in the vicinity of the welding arc. The measurement method presented in the article enables determination of radiant exposure of arc ignition radiation.
