Google Patents US2546153A - Retractable air inlet screen for aircraft gas turbines Some welding curtains are designed to accommodate a large work area, whereas others are smaller and more limited in their applications.US2546153A - Retractable air inlet screen for aircraft gas turbines Welding curtains are available in a variety of sizes. You should also consider the size when choosing a welding curtain. If you're working inside a semi-transparent welding curtain, you'll be able to see other workers outside of the curtain. With semi-transparency, you can see through the welding curtain. Some of them are a solid color, for example, whereas others are semi-transparent color. While all welding curtains are designed to create a barrier around a welding area, there are different types of welding curtains. With a welding curtain, bystanders won't be directly exposed to these fumes. Welding arcs can produce harmful fumes that, if inhaled, can increase the risk of respiratory disease. Welding curtains also protect bystanders from harmful fumes. Welding curtains are designed to block UV light so that bystanders are protected from potential eye injury. Welding arcs produce powerful ultraviolet (UV) light, which can injure a bystander's eyes if he or she isn't wearing the appropriate eye protection. But it's not just the heat of a welding arc that cause injury. Welding arcs obviously produce a lot of heat, so there's an inherent risk of burn injuries if bystanders are exposed to them. Injuries can occur to other workers around these welding areas.Ī welding curtain can lower the risk of injury to nearby workers by shielding them from welding arcs. It's not just professional welders who sustain injuries, though. Bureau of Labor Statistics (BLS), roughly a half-million workers in the United States are injured each year during a welding-related accident. Using a welding curtain can lower the risk of injury. The Importance of Using a Welding Curtain Once assembled, a professional welder can enter the welding curtain to begin working. They are assembled around a welding work area. Overview of Welding CurtainsĪ welding curtain is one or more pieces of heat-resistant material that's designed to create a barrier around the workspace where welding is being performed. To learn more about welding curtains and why they are important, keep reading. It's a relatively simple item that can protect workers from serious injury. To protect against injury, professional welders often use a welding curtain. Some of them, in fact, can produce heat in excess of 15,000 degrees Fahrenheit. Because they are designed to melt metal, welding arcs can get very hot.
