Red Seal Welding Practice Exam

Question: 1 / 400

What is the purpose of a welding helmet?

To improve vision while welding

To protect the welder's face and eyes from harmful UV and IR radiation

The primary purpose of a welding helmet is to protect the welder's face and eyes from harmful ultraviolet (UV) and infrared (IR) radiation generated during the welding process. When welding, intense light and radiation are produced, which can cause severe eye damage, known as arc eye, as well as skin burns. The helmet is designed with a darkened visor that filters out this harmful radiation, allowing the welder to see the weld pool while safeguarding against the intense brightness and infrared heat.

While improving vision, reducing noise, and providing thermal insulation might be seen as beneficial aspects, they are not the primary functions of a welding helmet. The helmet's main focus is on safety, making it an essential piece of personal protective equipment for welders.
