All of the options mentioned are reasons to remove surface contamination before making a repair weld. Welding on a contaminated surface can release hazardous materials, such as lead or asbestos, which can harm your health. Additionally, the heat emitted during welding can cause chemical reactions with contaminants, resulting in toxic fumes or other safety hazards. Moreover, skin or eye contact with particulate matter or fumes produced by contaminants can be irritating and potentially cause adverse health effects. Therefore, it is critical always to remove surface contamination before making a repair weld.
