2/20/2019 0 Comments Welding Shades ExplainedWelding is a serious job and there is no doubt about it. The welding safety concerns should be taken seriously whether you love MIG welding or TIG welding. From face burn to the loss of eye-sight, the damages could be unthinkable. There are lots of protective gears that the welders’ uses like the welding helmet, respirators, goggles, and so on. You need to understand how they work to get the maximum benefits out of it. In this article I am not gonna talk about all of the equipment. However, I will try to briefly explain what welding shades are and what they do to protect the welders. Just to give you a fresh start; shades ranges from 2 to 14. The number 14 is the darkest. The darkest shade will allow you to filter out the harmful UV and IR that can seriously damage your eyes. Welding Lens I need to talk about it because the welding lens plays a great role protecting your eyes. Are you familiar with the photokeratitis? It’s so painful condition in your cornea that caused by electromagnetic energy generated from the arc. If you use the lens with the perfect shade number, these horrible conditions can be avoided easily. That’s why understanding the welding shades is so important. Shades number can go as high as 14. Light radiation is common in arc welding. The shade number gives you the hint exactly how much of this light radiation is allowed to enter into your eyes though the lens. So, the principle is simple: The higher the shade number the lower the light radiation enters into your eyes through the lens. Wearing eyewear in addition to the lens is common to lessen the impact of the light radiation. Getting the right shade could be tricky and troublesome for the beginner. They don’t know which shade number to use. In that case OSHA recommends going for the high shade number first so that the weld zone becomes too dark to see. Then go for the lighter shade to see the weld zone to ensure your welding safety. Conclusion Understanding and using the right shade during the welding will protect your eyes from the dangerous UV rays, no doubt. If you had any confusion about the lens shade, I hope I have explained it pretty well.
