About welding fume

The precise composition of welding fume differs based on the application and welding means being utilized. There are two major components:

  1. The fusion of metals generates many potentially poisonous gases, counting carbon dioxide, hydrogen fluoride, argon, carbon monoxide, iron oxide, nitric acid, ozone, nitrogen, phosgene, and nitrogen dioxide.
  2. Metal dust particles produced by welding are so fine and extremely concentrated they seem like smoke, making a high threat of inhalation. This filth can be formed from some toxic metals, such as lead, aluminium, manganese, cadmium, antimony, beryllium, chromium, iron, arsenic, molybdenum, etc.

Daily thousands of workers in welding workshops worldwide come in contact with hazardous welding fumes and vapours which make them unwell, at times enduringly. Simultaneously, the Occupational Safety and Health Administration (OSHA)states an inclusive set of laws and principles intended to aid guarantee security while welding and prevent welding fumes spoiling the atmosphere of the workplace. Explore and learn the 11 ways to improve welding safety.

The trouble is that harmful fumes and vapours cannot be seen, making it impractical to visually measure the efficiency of ventilation. Moreover, the truth is that lots of organizations undervalue the result of fume exposure and do not utilize useful means like welding fume extractor for extracting or filtering the air in which the welders work.

How to reduce welding fumes?

Here are some important tips to control welding fumes:

  1. Have a proper ventilation system

Conventionally, push/pull systems are employed in many workplaces today, mainly in big welding halls and on big, complex elements. A spherical airflow is sustained as warm, contaminated air increases and is drawn into the duct system when what is thought to be fresh air is pushed out into the manufacturing hall.

One more alternative is a system that utilizes layer ventilation and displacement flow standards with cleanable filters. Rather than a broad duct system, this depends on a central air tower with no ductwork or pipes.

  1. Take out the coatings in the weld area

The weld area should be cleaned before welding and this is vital not only to guarantee a good weld but also as covered material would bring in other dangers to the weld fume. Coatings can comprise metalworking liquids, oils and rust inhibitor, galvanized steel, etc. which has zinc that generates zinc oxide fumes.
