UV  radiation intensity measurement plays an important role in arc welding. Arc welding will cause a lot of harm to the human body. Electric welding arc mainly includes infrared, visible light and ultraviolet light. These all belong to hotline spectrum. The main harm of ultraviolet rays to the human body is photochemical action, which causes damage to human skin and eyes. After the skin is exposed to strong ultraviolet radiation, it can cause dermatitis, erythema, etc. So UV radiation intensity measurement is very necessary. UV radiation intensity of arc welding must be controlled in certain ranges. Multi-probe UV light meter is a professional instrument used to test the UV radiation intensity.

1. Arc welding and its principle

Electric arc welding is a phenomenon of arcing short circuit. To put it simply, in the process of electric welding, an arc is established after the electrodes are contacted. After the contact, the arc with a high local temperature is generated as a source of ignition. The arc can be divided into an arc between the charged conductors, an arc between the live conductor and the ground and creepage of the insulating surface depending on the location of the arc. Among these arcs, there are strong light, infrared rays, ultraviolet rays, x-rays, etc. Some of them have great harm to the human body.

2. Multi-channel UV light tester measure arc welding UV radiation intensity

Since the arc welding is harmful to the human body, we use a multi-probe UV light tester to detect the arc welding. The main frequency ultraviolet light of the arc welding is 365 nm, we generally use the Linshang LS125+UVA-X0 probe multi-channel UV light tester to detect the ultraviolet radiation intensity and energy of the arc welding. The probe has a spectral response ranging from 315 nm to 400 nm and a peak wavelength of 365 nm. Not only the UV radiation intensity detection of arc light can be performed. It can also be used for energy detection of the curing strength of high pressure mercury lamps.

The Linshang LS125++UVA-X1 UV meter is also suitable for UV energy detection of welding lone beams. The spectral response range is 260-400 nm and the peak wavelength is 365 nm. This multi-channel UV light tester has a wider spectral response range. It is suitable for welding arc light, UV aging, UV energy detection in solar light sources.

Although ultraviolet light in the arc welding is inevitable during welding, we can take some protective measures during welding to reduce the radiation of ultraviolet light to the human body. Multi-probe UV meter which can measure UVA,UVB and UVC wavelengths is your best choice.
