Does welding produces radiation?
Welding is a process of joining two pieces of metal by heating them to a high temperature and then applying pressure to fuse them together.
Welding is widely used in many industries, including construction, automotive, and aerospace. However, there is a common concern about whether welding produces radiation.
Radiation is a form of energy that can be emitted by various sources, including the sun, nuclear power plants, and X-ray machines.
There are two main types of radiation:
- Ionizing and
- Non-ionizing.
Ionizing radiation has enough energy to remove electrons from atoms, while non-ionizing radiation does not.
When it comes to welding, there are several types of radiation that can be produced. These include ultraviolet (UV) radiation, visible light, infrared (IR) radiation, and electromagnetic radiation.
The amount and type of radiation produced during welding depend on various factors, such as the welding process, the type of metal being welded, and the welding conditions.
Electromagnetic radiation is also produced during welding, which can cause interference with electronic devices. This type of radiation is not harmful to humans, but it can cause issues with sensitive equipment.
Types of radiations produced by welding
Welding produces several types of radiation, which can be harmful to human health and can cause interference with electronic devices.
The types of radiation produced during welding include:
Ultraviolet (UV) radiation
One of the primary sources of radiation during welding is UV radiation. UV radiation has a shorter wavelength than visible light and can cause skin and eye damage.
Welders who are exposed to UV radiation without proper protection can develop skin burns, eye irritation, and even long-term eye damage.
This type of radiation has a wavelength between 100 and 400 nanometers (nm).
Visible light
Welding produces visible light, which is a type of electromagnetic radiation that can be seen by the human eye.
Welding produces visible light, which has a wavelength between 400 and 700 nm and can be seen by the human eye. Exposure to visible light during welding is not harmful to human health.
Infrared (IR) radiation
Another type of radiation that can be produced during welding is IR radiation. IR radiation has a longer wavelength than visible light. IR radiation has a wavelength between 700 nm and 1 millimeter (mm).
Welders who are exposed to IR radiation without proper protection can develop skin burns, eye irritation, and even long-term eye damage.
Electromagnetic radiation
Welding can produce electromagnetic radiation, which can cause interference with electronic devices. This type of radiation is not harmful to humans, but it can cause issues with sensitive equipment.
How can Welding radiation affects the skin?
Radiation can affect the skin in different ways depending on the type, intensity, and duration of exposure. In welding, the skin is typically exposed to ultraviolet (UV) and infrared (IR) radiation, which can cause different effects on the skin.
Exposure to UV radiation can cause acute and chronic damage to the skin. Acute exposure to high levels of UV radiation can cause erythema, or skin redness and irritation, similar to sunburn.

Chronic exposure to low levels of UV radiation can cause photoaging, which is characterized by the premature aging of the skin, including wrinkles, fine lines, and hyperpigmentation.
In severe cases, chronic exposure to UV radiation can also lead to skin cancer, such as squamous cell carcinoma and basal cell carcinoma.
IR radiation can also cause skin damage, especially at high levels and prolonged exposure.
Exposure to IR radiation can cause skin burns, which can be painful and may take a long time to heal. IR radiation can also cause damage to the skin’s collagen, leading to skin aging and wrinkles.
It’s essential to note that the effects of radiation on the skin can vary depending on the person’s skin type, age, and overall health.
People with fair skin and those who work in the welding industry for a long time may be at a higher risk of developing skin damage from radiation exposure.
How to protect from welding radiation?
To prevent skin damage from radiation exposure during welding, welders should wear protective clothing, such as a welding jacket, gloves, and a helmet with a UV/IR filter.
They should also work in a well-ventilated area and take breaks regularly to reduce the time of exposure. If welders notice any skin changes or abnormalities, they should seek medical attention promptly.
To protect yourself from welding radiation, you should take the following precautions:
Wear protective clothing: Protective clothing such as a welding jacket, gloves, and boots can help shield your skin from radiation exposure. It’s essential to wear clothing that covers as much skin as possible to prevent exposure.
Use a welding helmet with a UV/IR filter: A welding helmet with a filter that blocks both ultraviolet (UV) and infrared (IR) radiation is crucial to protect your eyes and face from radiation exposure.
Work in a well-ventilated area: Proper ventilation can help reduce the amount of radiation exposure. Make sure to work in a well-ventilated area with good air circulation.
Take breaks: Taking regular breaks can help reduce the time of exposure to radiation. It’s essential to rest and allow your body to recover from the effects of radiation.
Follow proper welding techniques: Follow proper welding techniques and procedures to reduce the amount of radiation exposure. This includes maintaining the proper distance between yourself and the welding equipment and using shielding gas to reduce radiation exposure.
List of PPE to protect from welding radiation
Personal Protective Equipment (PPE) is essential to protect welders from radiation exposure during welding. Here are some of the most common types of PPE used to protect welders from radiation:
Welding helmet: A welding helmet is one of the most crucial pieces of PPE for a welder. It protects the face and eyes from harmful radiation produced during welding.
Welding goggles: Welding goggles can be worn under a welding helmet to provide additional eye protection. They are especially useful for welders who wear prescription glasses.
Welding gloves: Welding gloves protect the hands from radiation exposure, as well as heat and sparks produced during welding.
Welding jacket: A welding jacket provides full-body protection from radiation exposure and sparks produced during welding.
Welding apron: A welding apron is an alternative to a welding jacket that can provide similar protection for the upper body.
Welding boots: Welding boots are designed to protect the feet and ankles from radiation exposure and other hazards in the welding environment.
Respirator: A respirator can be used to protect against fumes and other airborne particles produced during welding.
Earplugs or earmuffs: Ear protection is essential for welders who are exposed to loud noises from welding equipment.
Welding curtain: A welding curtain can be used to create a barrier between the welder and others in the work area, protecting them from radiation exposure.
It’s essential to select PPE that is appropriate for the type of welding being performed and the level of radiation exposure. PPE should be inspected regularly and replaced as necessary to ensure that it provides adequate protection.
Should you worry about welding radiation?
Welding radiation can pose a potential health hazard to welders if they are not adequately protected.
The level of concern depends on several factors, including the type of welding being performed, the duration of exposure, and the type of PPE being used.
While all forms of welding produce radiation, the level and type of radiation can vary depending on the welding process.
For example, arc welding, which uses an electric arc to melt metal, produces higher levels of UV and IR radiation than other types of welding. However, TIG welding produces less radiation than MIG or stick welding.
The duration of exposure is also a critical factor in determining the potential health risks of welding radiation.
Welders who work in the industry for many years are more likely to develop long-term health problems from radiation exposure than those who perform welding as a hobby or infrequently.
Proper PPE is essential to protect welders from the harmful effects of radiation exposure.
Welders who use appropriate PPE, including a welding helmet with a UV/IR filter, protective clothing, and gloves, are less likely to experience health problems from radiation exposure.
Conclusion
In conclusion, welding radiation can be a concern for welders if they are not adequately protected.
Welding does produce radiation, but the amount and type of radiation depend on various factors. Welders who work with UV and IR radiation should take precautions to protect themselves from exposure.
This includes wearing protective clothing, using a welding helmet with a UV/IR filter, and working in a well-ventilated area. By taking these steps, welders can reduce their risk of developing health problems from exposure to radiation during welding.
