Welding and cutting fume and smoke

Nederman has stationary and mobile solutions for extracting and filtering smoke from welding and cutting

International health organizations recognize the importance of preventing health risks associated with fumes and smoke generated during welding and thermal cutting. In many countries strict standards have been established to limit the permissible exposure limit (PEL). Welding smoke also damages sensitive machines like robots.

Cutting fume extaction

Extraction at source is the most efficient capturing solution for welding and cutting fumes

Wherever it is a viable solution, it has been proven that extraction at source is the most effective and efficient method of capturing and removing welding and similar fumes. Using this method, the risk of the welder or operator being subject to hazardous fumes is minimised. 

The necessary components to achieve proper source capture of welding fumes are an easily positioned fume extractor with a well-designed hood, proper airflow through the fume extractor and a conscientious welder who will position the hood in a manner that will draw hazardous fumes away from his or her breathing zone and avoid to spread the smoke in the premises.

Welding smoke and fume extraction at-source with arms

Nederman has a wide range of extraction arms in different designs. Full flexibility and easy to position. Arms can be fitted to both stationary and mobile vacuum and filter units.

On-torch welding fume extraction

As an alternative to the hood and arm fume extractor, on-torch extraction can be used. The on-torch extraction systems extract the fumes directly from the welding torch. The extraction systems are available as both mobile single user extraction units and central extraction systems serving several extraction points.

Robotic welding

Nederman solutions for automatic welding processes include both on-torch extraction and extractions systems with hoods for welding fume extraction.

Smoke and fume extraction from thermal cutting processes

The fumes generated from the cutting process are extracted through the grates of the cutting table.

Energy saving systems

To save energy and operation cost Nederman offers a wide selection of motor dampers, fan control units and fan inverters, complementing stationary units for energy efficient on-torch welding fume and smoke extraction.

Why central ventilation systems are no good

Central ventilation systems or extraction hoods over workbenches are often completely inadequate. These systems are seldom cost-effective as they require a great deal of power to run and extract enormous quantities of heated air from the premises. Moreover, the welders or operators cannot avoid inhaling the welding fumes as these always contaminate the general airflow, forcing them to wear uncomfortable fresh air units in addition to central ventilation.

Health effects of welding and cutting fumes

Particles in welding fumes are small enough to be suspended in the air for a long time. They welding fume can be inhaled and penetrate into the innermost area of the lungs. Over time, the particles can even reach the bloodstream. Fume from MMA and FCAW welding usually contains significant quantities of Cr(VI), in particular when welding in stainless steel. This is important to observe because hexavalent chromium Cr(VI) has a very low exposure limit. There are also health risks from exposure of welding smoke due to the presence of manganese, nickel and other elements. 

Legislation are getting stricter in many countries with lower exposures limits for different types of particles. Market specific information can be found here.


Generation of welding fumes and smoke

Airborne particles from 2 weeks welding. One single welder produces 20-40 g fumes per hour which corresponds to about 35-70 kg per year
Airborne particles from 2 weeks welding. One single welder produces 20-40 g fumes per hour which corresponds to about 35-70 kg per year

Different welding methods give rise to different amounts of fumes containing different concentrations of hazardous substances. Among the high-risk elements are hexavalent chromium Cr(VI), manganese, nickel and lead. The particles at source are often extremely small; 0.01-0.1 μm which means they are very easy to inhale deep into the lungs.

Furthermore, not only welders are at risk in unsafe environments. Production equipment, as well as end products, are negatively affected from the lack of adequate safety measures. Automated welding equipment such as robots - and its operators - can be subject to residual fumes and also need to be protected.
