What is the purpose of fume extraction in welding?

  1. To enhance visibility during welding

  2. To remove harmful fumes and particles

  3. To cool down the welding area

  4. To protect tools from overheating

The correct answer is: To remove harmful fumes and particles

The purpose of fume extraction in welding is to remove harmful fumes and particles generated during the welding process. Welding produces hazardous fumes that may contain various toxic substances, including metal particles and gases, which can pose significant health risks to the welder and anyone in the surrounding area. By implementing effective fume extraction systems, these harmful substances can be collected and filtered out of the air, ensuring a safer working environment and minimizing exposure to toxic elements. This is crucial for maintaining occupational health standards and protecting the welder's long-term health. The other options do not accurately reflect the primary objective of fume extraction in the welding industry, as they pertain to aspects like visibility, temperature control, and tool protection rather than addressing the health concerns associated with welding fumes.
