Welding shields are essential personal protective equipment (PPE) used to protect the welder’s face and eyes from the hazards associated with the welding process, including intense light, UV radiation, and flying debris. These shields feature a darkened lens that prevents eye damage from the intense light and ultraviolet radiation emitted during welding. Welding shields are available in two main types: fixed lenses and auto-darkening lenses. Fixed-lens shields have a standard shade, while auto-darkening shields automatically adjust to the light intensity, offering more comfort and protection for the welder. These shields must meet ANSI Z87.1 and SASO 2201 standards to ensure proper protection and safety.
Key Features:
- UV Protection: Shields block harmful ultraviolet rays that can cause eye damage or burns.
- Adjustable Fit: Many models offer adjustable headbands or straps for comfort and proper fit.
- Auto-Darkening Technology: Auto-darkening shields automatically adjust to the brightness of the weld, providing optimal protection and visibility.
- Impact-Resistant: Constructed with durable materials to withstand impact and provide long-lasting protection.
Types and Standards:
- Fixed-Lens Shields: Offer a single shade of lens for welding, often at a fixed level of protection.
- Auto-Darkening Shields: Automatically adjust to the changing light levels during the welding process, offering convenience and comfort.
- **ANSI Z87.1, SASO 2201: Standards ensuring that welding shields provide adequate protection from the hazards of welding.
Brands Available:
3M, Lincoln Electric, ESAB, Hobart, and Optrel are leading brands known for producing high-quality welding shields.
General Maintenance:
Inspect the welding shield regularly for cracks or damage to the lens. Clean the shield after each use with a soft cloth to remove welding spatter or debris. Ensure the auto-darkening lens functions properly by testing it with a light source. Replace the lens if it becomes scratched or damaged.
