Fine dust: the invisible danger

The danger is in the unseen: Fine dust is a threat to people. Specifically, ultra-fine dust particles constitute a health threat. This finding is becoming more accepted in science and practice and can be applied directly to welding or rather … >> more

MIG welding: highly hazardous despite lower quantities of welding fumes

MAG-welding: common, despite high emissions of welding fumes

Hazardous substances such as welding fumes can harm employees

Neues BAuA-Faktenblatt: Gafrhstoffe wie Gase, Dämpfe oder Rauch verursachen Berufskrankheiten - so auch Schweißrauch.

Mobile, stationary, central: Extraction systems for welding fumes at a glance

Mobile extraction devices and filter devices: high movement radius thanks to almost unlimited mobility usable also for changing workstations shorter extraction arms thanks to proximity to workpiece Stationary extraction and filtering devices/systems: space-saving installation at solid welding stations so good … >> more

Air recirculation during welding: Yes – see conditions

Air circulat solutions are becoming increasingly more important in planning extraction systems and filter technology in operations. They promise lower energy costs. But a recirculation of filtered air is not suitable in all cases – in some cases it is … >> more

Manual arc welding: Chromium VI compounds and more besides in the welding fumes

Up to the formation of chromium VI compounds: In manual arc welding, the kind of hazardous substances in the welding fumes is very much determined by the metal of the core rod and its covering. Particularly hazardous are high-alloy rod … >> more

Factors for the amount of welding fumes

How much welding fumes created in any welding work depends on many factors: Not only the method and the materials used influence the amount of welding fumes. The welding fumes emissions, expressed in mg/s, are smaller than the smoke and … >> more

Gas welding: Nitrogen and carbon hazard in welding fumes

Whether your welding sheets of pipes: Oxyacetylene welding (gas welding) stands for high accuracy. But even this relatively slow process releases hazardous substances and not only the dangerous nitrogen dioxide. Have you ever been in confined spaces where oxyacetylene welding … >> more

Welding aluminium: dangerous formation of oxides and ozone

Many welding companies ask themselves one question when it comes to the welding of aluminium: Is an air pollution control system absolutely necessary when working with this comparatively lightweight material? Studies show, however, that the material does indeed pose a … >> more
