How bright is a welding arc compared to the sun?
A welding arc is not brighter than the sun, no matter how bright it may seem to you. Welding arcs are bright and produce a lot of heat. Welding produces around 3400 K of heat, whereas the sun produces 5800 K. If we were to measure brightness through radiated heat, then the sun is the undisputed winner in this battle.
How bright is an arc flash?
The light intensity of an arc flash 3 meters from the source is over 1 million lux, and a more recent arc flash test recorded 13.1 million lux—approximately 130 times brighter than direct sunlight!

Can a welding arc blind you?
A flash burn occurs when you are exposed to bright ultraviolet (UV) light. It can be caused by all types of UV light, but welding torches are the most common source. That’s why it’s sometimes called ‘welder’s flash’ or ‘arc eye’. Flash burns are like sunburn in the eye and can affect both your eyes.
Is welding burn the same as sunburn?
Welding arcs and flames emit intense visible, ultraviolet, and infrared radiation. UV radiation in a welding arc will burn unprotected skin just like UV radiation in sunlight. This hazard is true for direct exposure to UV radiation as well as radiation that is reflected from metal surfaces, walls, and ceilings.
Is TIG welding brighter than MIG?
Through my experience TIG is brighter than short circuit MIG.
What is the most difficult weld to make?
TIG welding is the hardest form of welding to learn for a variety of reasons. The process of TIG welding is slow and takes time to get used to as a beginner. A TIG welder requires a foot pedal to feed the electrode and control the variable amperage while maintaining a steady hand at the welding torch.
How bright is a welding light?
Light. Contrary to what many people may say, a welding arc is not brighter than the sun. However, exposure to welding arc light is brighter than any sun you will experience beneath the atmosphere. The arc gives off ultraviolet light that can burn your eyes and skin by being exposed to it.
How far can 240V arc?
@ppumkin: so given a linear scale, that would mean 240V could arc about 0.24mm through air, but no answer has given this figure yet. Under ideal conditions probably. But the problem is to start the arc’ing process, since if there is a less resistive route, like a PCB trace the chances of arc’ing are less likely.
Why is a welder so bright?
The radiation comes from oscillating electrons (regardless of whether there is an electric current). Welding reaches temperatures high enough to cause significant emission of UV light. Oxyacetylene and oxyhydrogen flames can both be over 3000 C degrees and therefore can produce hazardous amounts of UV light.
Can welding give you a tan?
As a welder, you can tan while at work. Talk about a good deal! At least until you’ve got skin cancer or 3rd degree sunburns. Pro-tip: You can avoid those unsightly tan lines by welding naked (ouch).
How far away can you get welders flash?
Radiation intensity is strongly dependent on the distance from a welder’s arc. Therefore, if you are a short distance from an arc, even a very short exposure to the arc flash can result in injury. As a result, personnel must be subject to adequate protection if they’re closer than 10 metres from an arc flash.
How far away can you look at welding?
The US Army have carried out trials which propose distances of between 3 and 20 metres for an exposure time of 10 minutes for MMA (SMA), MAG (GMA) and FCAW in order for UV exposure to be below the US daily threshold limit value.

Should you wear sunscreen while welding?
Welder’s Occupational Risks
The good news is that many welding-related injuries are preventable with the proper protection. Like wearing a physical block sunscreen with Zinc Oxide that provides a physical protection against UVC, UVB and UVA Rays up to 400 nanometers which makes a Broad Spectrum Sunscreen.
Can you weld with shade 5 glasses?
Can You Weld With Shade 5 Glasses? Welding with shade 5 is usually sufficient for light work. If your activities involve arcs such as MIG welding, shade number 5 is unsuitable. The shade is not dark enough to protect your eyes from the IR of the arc.
Will sunblock stop welding burn?
Well, the answer is a big YES! Sunscreens can act as an effective precautionary measure to deal with the harmful effects of UV radiation emitted during welding procedures.
What type of welding has the brightest arc?
Gas Tungsten Arc Welding (TIG) is probably the highest quality and most expensive of the arc welding processes. It is generally performed manually; however, there are some automatic applications.
How hot is a weld puddle?
While different metals require different temperatures, arc welding is usually performed with an arc temperature of roughly 10,000 degrees Fahrenheit.
Why should the arc welder wear clothing without pockets and cuffs?
Welders should stray away from wearing clothing that has cuffs or open pockets, as these can trap molten metal or sparks. Traditional materials (leather, cottons and wool) and more modern materials should offer comfort and protection for welders.
Which weld joint is strongest?
TIG welding produces the strongest type of weld.
What welding is the strongest?
Bottom Line. TIG welding produces cleaner and more precise welds than MIG welding or other Arc welding methods, making it the strongest. That said, different welding jobs may require different methods, while TIG is generally stronger and higher in quality, you should use MIG or another method if the job calls for it.
Is it better to weld up or down?
For material thicker than sheet metal, vertical welding generally should be performed uphill. Welding thinner sheet metal can be performed downhill because less penetration is needed, and the faster travel speed produces cooler temperatures that prevent burn-through.
Is a welding arc hotter than the sun?
No matter the assumptions, the simple fact is that a welding arc is not hotter than the Sun, nothing is. The heat produced by the Sun is 5800 K. And the temperature of the Sun’s surface is about 10,000 degrees F, making it about 8.4 times brighter than the brightest welding arc out there.

How hot is a TIG welding arc?
TIG welding (GTAW or gas tungsten) is an arc welding process that operates at high temperatures (over 6,000 degrees Fahrenheit) to melt and heat metals. While it is more expensive than stick welding, it is cleaner and more versatile (works on steel, aluminum, brass and many other metals).
How hot is a SMAW arc?
Most SMAW arcs have a effective temperature of approximately 11,000 degrees Fahrenheit or 6,100 degrees Celsius.
