The process of welding might seem like a simple process because pressure or heat joins 2 metals together. But the truth is, the whole process is quite risky. Whether the welder is just a newbie or professional, the individual has to wear all the safety equipment during the process. And one such equipment among the many types is the welding helmets. It is the foremost equipment that a welder should compulsorily wear.
Welding helmets may not seem like a big deal, but it has several benefits. Below are some of the advantages of welding helmets and the types that are available in the market.
Benefits of welding helmet
- Protects the head – like any helmet, your head remains secured with a welding helmet if the unexpected happens.
- Protects the face – these helmets are to protect the face from radiation. Radiations like IR (infrared) and UV (ultraviolet) are emitted by different materials during welding.
- Protects the neck – the welding helm can safeguard the user’s neck and face against sparks, burns, and heat due to the process.
- Protects the eyes – arc eye is a condition caused when the cornea gets swollen due to arc welding. This arises if the cornea gets exposed to UV radiation repeatedly.
Types of welding helmets
Though any welding helmet is to protect the welder, each type comes with unique features. So, a welder can choose based on his preference.
- Passive welding helmets
This is a basic type with the same effect as that of modern types. It can protect the welder from sharp objects, heat, and UV rays from the welding process. Another advantage of this type is that it is inexpensive.
- Auto-darkening welding helmets
This is a helmet with the lens with automation, so no need to repeatedly adjust them. The helmets detect the emitted light during welding and can calibrate the lens accordingly. The only downside is that this is quite expensive.
- The solar-powered lens helmet
The helmet uses a battery for power start. But for operation, the solar energy source will help to keep going. They are a more economical option. There is an automatic switch off the lens when the helmet is not in use. The only negative about this type is that you cannot use it whenever you need. The welder has to remember to keep the helmet for recharge under the sun before the day of the project.
- The battery-powered helmet
This type uses replaceable or rechargeable batteries made using lithium. Replaceable batteries mean spending will be more. So this is a matter of preference.
- The fixed and variable shade lens welding helmet
They come in the shade level of 10. They cannot adjust to differing arc brightness. They are ideal for welders who often work on a particular type of project. On the other hand, the variable shade helmet can adjust to various brightness emitted during the welding process. This can give good visibility to the welder.
In the world of welding, the protective shadow for the welder is the welding helmet. Having this protective equipment can seem unnecessary, but it affects the way a welder does his job.
