Understanding Welder’s Flash: Causes And Symptoms
Welder’s flash, also known as arc-eye, is a condition that affects the eyes due to exposure to ultraviolet (UV) rays emitted by welding machines. This condition occurs when the cornea, the transparent outer layer of the eye, becomes inflamed as a result of intense UV radiation. Symptoms of welder’s flash include redness, watering, pain, sensitivity to light, and a gritty feeling in the eyes.
The main cause of welder’s flash is the direct exposure to the UV rays produced during welding. These rays are emitted by the welding arc, which is a high-intensity light generated by the welding process. When a welder does not wear appropriate eye protection, such as specialized welding goggles or helmets, their eyes are vulnerable to the harmful effects of UV radiation. Prolonged exposure to these rays without protection can cause significant damage to the cornea, resulting in the symptoms associated with welder’s flash.

Prevention And Protection: The Importance Of Welding Goggles And Helmets
To prevent welder’s flash and protect the eyes from the harmful UV radiation emitted during welding, it is crucial to wear specialized welding goggles and a helmet. These protective gear items are designed to shield the eyes from the intense light and UV rays.
Welding goggles feature filters that block out most of the harmful radiation while still allowing welders to see their work clearly. These goggles are an essential part of any welder’s gear to ensure eye safety.
Welding helmets are also equipped with UV filters and additional features such as auto-darkening lenses that automatically adjust the level of darkness to protect the eyes from sudden bright flashes. These helmets provide full face and neck protection, ensuring that welders are shielded from both direct and indirect exposure to UV radiation.
Investing in high-quality welding goggles and helmets is essential to reduce the risk of welder’s flash and protect the long-term health of the eyes. So, make sure to prioritize safety by using the right protective gear during welding operations.
First Aid For Welder’s Flash: Flush And Remove From Light Source
If a welder experiences symptoms of welder’s flash, immediate first aid is necessary to alleviate discomfort and minimize potential damage. The first step is to remove the patient from any light source, as exposure to bright light can exacerbate the symptoms and prolong recovery. Once in a dark or dimly lit area, the eyes should be flushed with an appropriate eye wash or saline solution to help soothe the inflammation and remove any foreign objects that may have entered the eyes during welding.
It is crucial not to rub or touch the affected eyes as this can further irritate the cornea. Instead, gently rinsing the eyes with the eye wash or saline solution should provide relief. Cooling the eyes with a cold compress may also help reduce swelling and alleviate discomfort. However, it’s important to note that first aid measures are intended to provide temporary relief, and seeking professional medical attention promptly is imperative to ensure that no serious damage has occurred to the cornea.
Seeking Medical Attention: Ensuring Cornea Safety
While arc-eye symptoms usually clear up within a day or so, it is essential to seek medical attention to ensure the safety and well-being of the cornea. The inflammation caused by welder’s flash can leave the cornea vulnerable to potential infections and complications if not properly treated. An eye care professional will be able to examine the eyes, assess the severity of the condition, and provide appropriate treatment.
In some cases, specialized eye drops may be prescribed to alleviate symptoms and promote healing. These drops can help reduce inflammation, relieve pain, and prevent infections. Additionally, if any foreign bodies, such as tiny metal particles, have entered the eyes during welding, medical assistance is essential for their safe and complete removal. Prompt medical attention will ensure the best possible outcome and prevent any long-term complications.
Choosing The Right Protection: Selecting The Appropriate Filter For Welding
Choosing the right protection for welding is crucial to prevent welder’s flash and protect the eyes from harmful UV radiation. As the damaging radiation from welding is not visible to the naked eye, selecting the appropriate filter is essential. In Europe, the British Standard BS EN 169 provides guidance on selecting the scale number of a protective filter suitable for welding. This standard establishes specifications for filters that offer the necessary level of protection against UV radiation.
Similarly, in the United States, the American National Standard Institute (ANSI) in conjunction with the American Welding Society (AWS) has developed the ANSI/AWS F2.2 lens scale selector. This tool assists welders in determining the appropriate filter shade number based on the welding process, material, and other relevant factors. Following these guidelines ensures that welders are adequately protected from UV radiation while still being able to see their work clearly.

Frequently Asked Questions
What causes welding flashes?
Welding flashes occur due to the exposure of the cornea to intense ultraviolet radiation emitted by the arc during welding. This high-energy radiation damages the delicate cells of the cornea, leading to inflammation and the development of arc-eye or welder’s flash. Interestingly, individuals often remain unaware of their significant exposure until hours after the welding process when the symptoms start to appear, highlighting the delayed onset of the condition.
Is welding flash UV light?
Yes, welding flash does emit UV light. When engaging in electric arc and laser welding, UV radiation is released. This exposure includes both direct UV radiation emitted by the arc and the UV radiation reflected off surfaces nearby. Therefore, it is crucial to protect oneself from potential UV hazards while performing welding tasks.
What do you use for welders flash?
To alleviate welder’s flash, it is commonly recommended to employ specialized eye drops or ointment with topical antibiotics, specifically tailored for eye care. These aids are crucial as they serve to prevent infections from developing in the cornea, which may be compromised due to the damage caused. Additionally, some eye specialists may administer steroid eye drops as a means of diminishing inflammation and minimizing the risk of scarring, ultimately aiding in the recovery process.
What is flash arc welding?
Flash arc welding is a variant of resistance welding that relies on the use of an electric arc to generate heat between the two pieces of metal to be joined. Unlike flash welding, which does not use any filler metals, flash arc welding utilizes a consumable electrode made of the same material as the base metals. When the electrode tip touches the workpieces, an intense arc is created, melting the metals and forming a strong weld. This process is commonly used for welding metals with different melting points or thicknesses, as it allows for better control over the welding parameters and helps achieve desired properties in the final weld.
