The welding helmet is included as part of the welding equipment when beginning welding training. Choosing the right welding helmet will not only keep a welder safe and comfortable on the shop floor, but it will also increase productivity and weld quality. Here are some things to think about when selecting a welding helmet.
Welding Helmets: How Do They Work?
Arc welding emits three types of light that can cause eye damage: ultraviolet, infrared, and visible. 2 Welders are also vulnerable to burns caused by sparks and hot molten metal. A welding helmet is intended to shield a welder's face and eyes from these hazards.
The most basic helmets consist of a nonflammable face shield attached to the welder's head by an adjustable strap. A rectangle is cut out of the shield to replace the welder's eyes. A lens is protected by a screen within this rectangle. To protect the welder's eyes from the various types of harmful light emitted by the arc, the lens is coated and darkened. The darker it is and the more light it filters, the higher the shade level.
One of the first things to look for in a welding helmet is whether or not it has been tested and approved by the American National Standards Institute (ANSI). This ensures that the helmet keeps you safe. For face and eye protection.
What Kinds of Welding Helmets Exist?
Welding helmets have become more complex over the years. While these helmets have more features that can improve protection, convenience, and comfort, they are also more expensive.
The greater the strain on your neck, the heavier the welding helmet. A heavy one may be uncomfortable or painful if you will be welding for several hours at a time. Welding helmets with plastic shells are typically lighter. A hood with multiple and/or pivot-style bands can displace the weight of the helmet and better secure it to the head, resulting in a more comfortable fit. 6 The reduced risk of work-related stress injuries is a significant advantage of the lighter helmet. Lighter helmets, on the other hand, are more expensive
Lenses that are passive
Passive lenses, also known as "standard lenses," are only available in one color. The welder wears the helmet up, away from his or her face, to see the work and properly position a welding torch, electrode, or gun. The welder snaps his or her neck just before striking the arc to flip the helmet into the proper position to shield the face and eyes.
For years, passive lenses have provided adequate protection to welders, and they are less expensive than auto-darkening lenses. Welders must flip passive helmets into place, which is not the most ergonomic option and can cause neck pain. Furthermore, if the welder fails to snap the hood into place at the proper time, his or her eyes may be exposed to harmful light. Welders who are inexperienced may be unable to hold the electrode in place while flipping the helmet down, resulting in poor or even defective welds.
Lenses that automatically darken
Auto-darkening lenses, as the name implies, change shades to meet the needs of the welder. When the welder needs to see the work, sensors in the hood reduce the shade of the lens. When the welder strikes the arc, these sensors detect it and darken the lens to a higher level, depending on the process.
Welders benefit from auto-darkening lenses because they eliminate the need to flip the helmet into position once the arc is struck. These welding hoods are more comfortable and allow the welder to produce higher-quality work. Auto-darkening lenses, on the other hand, are frequently more expensive. 9 10 Welders who begin with an auto-darkening hood may find it difficult to weld with a passive hood
Additional Considerations: Auto-darkening helmets are available in a variety of shading and sensor configurations. Essentially, the more sensors and shades a helmet has, the more work a welder can do safely. What Is the Best Welding Helmet?
When choosing a welding helmet, as with other welding safety equipment, there are several factors to consider. Consider the length of time spent under the hood, the types of welding jobs available, and your financial situation when weighing your options. While having a welding helmet with all the bells and whistles is nice, it is not always necessary.
