03 / WELDING FUMES
Articulated arms, downdraft tables, robotic cell hoods and filter extractors: we capture fumes at the workstation, from manual welders to robots, then filter them with mobile extractors or a centralised network with fan and activated carbon.
At the torch, before it reaches the welder's face
Static filter or activated carbon
Single workstation, workshop or robotic cell
Fumes subject to stricter requirements
WHAT'S AT STAKE
Ultrafine metal particles and gases: welding fumes rise straight towards the welder's face. Only capture placed as close as possible to the arc stops them before they are inhaled.
Have my workshop assessedCAPTURE AT THE WORKSTATION
The capture device follows the welder's movements and the size of the parts: arms for manual workstations, tables for small parts, built-in hoods for robots.
Swivelling, self-supporting arms brought above the weld, then repositioned for each part.
The table doubles as a workstation: fumes are extracted through the worktop and the backboard. ST 120, ST 150 and SV ranges.
Capture devices built into the cell or the torch, designed around the robot and its path.
FILTER
The choice depends on the number of workstations, arc time and the volume of air to treat.
Articulated-arm extractors: air is drawn in through the swivelling hood, passes through a flow divider, a synthetic pre-filter and a high-efficiency filter, then is discharged at the base of the unit.
For workshops with several workstations: a fan extracts fumes from the whole network and sends them to a filter unit with an activated carbon stage, which also retains gases and odours before discharge.
OUR METHOD
Every welding workshop is different: we start from the process and the workstations, not from a catalogue.
MIG, MAG, TIG, plasma or thermal cutting, metals welded and arc time.
Single workstation, line of workstations or robotic cell, and whether they run simultaneously.
Arm, table or cell hood, as close as possible to the arc without hindering the welder.
Single extractor or central unit, static filtration or activated carbon, air discharged or recirculated.

Processes used, number of workstations, part sizes and whether robots are used: a few details are enough to propose the right capture and filtration.
