AWS Welding Inspection and Testing Certification Practice Test

During welding, what is essential for ensuring adequate visibility of work?

1. Bright lighting

2. Proper lens shade

3. High-quality gloves

4. Strong ventilation

The correct answer is: Proper lens shade

To ensure adequate visibility during welding, having a proper lens shade is essential. The lens shade is designed to protect the welder's eyes from the intense light and harmful UV radiation generated during the welding process. It filters out excessive brightness while still allowing the welder to see the weld pool clearly. The right shade helps balance visibility and safety, enabling the welder to maintain focus and precision throughout the welding operation. While bright lighting can enhance visibility in the surrounding area, too much light can create glare or reflection, which may hinder the welder's ability to see in detail. High-quality gloves contribute to safety and dexterity, but they do not directly influence visibility. Strong ventilation is important for ensuring a safe working environment by removing fumes and gases, but it does not affect the welder's ability to see the work.
