WELDING
Welding + extraction = safe working
When welding metal parts in industry, harmful emissions such as smoke and fumes are released. To protect employees and to comply with applicable workplace limits (DGUV) and TRGS 528, these substances must be safely extracted and filtered. The technical design is crucial for effective extraction and an economical investment. Our flexible system components allow us to adapt our extraction systems specifically to your application, thus saving valuable energy and operating costs.
Cancer risk due to welding fumes
Due to their small size, perspiration smoke particles reach deep into the pulmonary alveoli (aveoli) when inhaled and settle there. Since 2018, welding fumes have been upgraded from possibly carcinogenic to to carcinogenic by the International Agency for Research on Cancer (IARC). This higher rating makes it imperative to minimize welding fume exposure. So-called »bystanders«, employees who weld only occasionally or work in the same room, are also at acute risk. In addition to arc welding, this also includes other processes such as gas welding (oxyacetylene process).
Extraction solutions for welding fumes
There are three technical solutions for the extraction of emissions during welding. With several workstations, large quantities of fumes and large workpieces, hall ventilation systems are usually more effective than point extraction systems.
SINGLE PLACE EXTRACTION
Extraction of individual or multiple workstations via an extraction unit
FILTER TOWER
Filtering the hall air via a stationary filter tower without a pipe system
HALL EXTRACTION
Filtering the hall air via a pipe system and stationary extraction unit
Welding fume filters from ABSAUGWERK
The R series fume filters have been specially designed for the extraction of fine smoke and fume particles and can be optionally extended with a HEPA H14 filter for carcinogenic stainless steel dust. In this process, the smoke is captured via an Extraction hood or Extraction arm and filtered in the extraction unit via several filter stages. The cleaned air can then be fed back into the hall or outside.
Thanks to the numerous configuration options, we can offer an optimal and future-proof extraction solution for every application.
Extraction from welding robots
Welding robots are already a reality in numerous automated industrial processes. The factors of quality, speed and reach play a particularly important role here. They are used to support work that is difficult to perform using manual welding methods.
But here, too, fumes and gases are generated that are hazardous to health and must be extracted from the surrounding area, especially to protect employees. The extraction systems must also be capable of filtering large quantities of smoke and capturing them at the point of origin with sufficiently high extraction power.
