Weld Fume Extraction Solutions

Weld Fume Extraction

Control of welding fumes in the workplace has always been a legal requirement for operators under the existing CoSHH Regulation 7. Some practical weld fume solutions BEAM can provide include:

  • Extraction of weld fume at source

  • Welding Enclosures at Robot Cells

  • On-torch weld fume extraction

HSE Welding Fume Advice


In February 2019, the HSE issued a safety alert updating its advice regarding the risks and controls of welding fumes. This is intended for those who undertake welding activities, including mild steel, and in any industry. 
  • Due to the reclassification of welding fume as a carcinogen, there is now no safe limit to exposure
  • General workplace ventilation would not be considered an acceptable solution.
  • The HSE recommend that engineering control solutions must be put in place for all welding, including outdoor work, and work of short duration.
We hold a Professional Certification from the Health and Safety industry body, Bohs, and recommend companies follow the latest advice based on the Hierarchy of Control.

 

Extraction of weld fume at source


BEAM have extensive experience providing LEV systems for welding fume extraction ranging from individual workstations to factory wide installations.
We have a wide range of extract arms ranging from 1m – 7m in length which provide weld-fume extraction at the source.
Our equipment range has unique innovations in the design which provides the following benefits to the operators;

  • Exo-parallelogram support is positioned on the outside of the extract hose therefore it avoids contamination with dust and soot which can lead to failure of internal hose supports.

  • The external hose is very accessible for service and maintenance and is available as a spare part in lengths to suit the client’s needs which reduces ongoing costs and downtime.

  • The support uses gas-struts to counterbalance the weight. This is a superior design which out-performs the commonplace alternative which is friction & spring types.

  • Our extract arms feature a flanged inlet which greatly improves the effective capture distance. In practice, this allows for fewer movements to reposition the arm over the workpiece and minimises the operator input and improves productivity.

  • We can offer control systems from basic manual operation to fully automatic start/stop and demand control of fans.

    In some situations, it may not be practical to install fixed extract arms, so a further solution could be Portable Fume Extraction, comprising of extract arm and integrated filtration unit. The picture below shows a free-standing mobile unit complete with integrated filter which is designed to provide weld fume extraction throughout a workshop floor.

BEAM can supply various options ranging from low cost disposbable filter systems to high specification HEPA units to suit individual requirements. Get in Touch to discuss your requirements.


 
 

Welding Enclosures at Robot Cells

Following the principles outlined within the Hierarchy of welding control, some manufacturers have introduced robotic welding cells which completely remove the operators from harm. Beam can advise on suitable extract systems, including enclosures, extract capacity, and offer complete solutions comprising the design, supply, installation and validation of the equipment.

The first picture shows an example of a telescopic extract arm located at a welding robot in a retracted position to facilitate product set-up and service. The second picture shows the extract arm extended to the working postion.



   

 

On-torch weld fume extraction 

This consists of a proprietary welding gun with integrated suction nozzle at the tip. This system can be beneficial where no other extract solution can be deployed due to restrictions within the location where the work is carried out.
Bohs website have a fume extract selector tool for owners which may be useful;
Beam can offer specialist high vacuum extraction equipment and matching ducting system to implement an on-torch extract system. We have a demonstration unit available and can offer a trial and further advice to suit our client’s individual requirements.
