Why Measure Welding Fumes?

Welding processes are classified into two groups: Fusion welding (Heat alone) and Pressure welding, (Heat and Pressure). Fusion welding involves three types: electric arc, gas and thermit. Visible smoke that contains harmful metal fume including aluminium, arsenic, beryllium, lead and manganese is produced during welding. Gases that pose suffocation risks such as argon, nitrogen, carbon dioxide, carbon monoxide and hydrogen fluoride are also produced.

WorkSafeNZ reports that welding fumes can cause serious health problems for workers if inhaled. Short-term exposure can result in nausea, dizziness, eye/nose/throat irritation. Prolonged exposure to welding fumes can lead to cancer of the lung, larynx and urinary tract, as well as nervous system and kidney damage.
