Limit values for welding fumes: Let’s count the particles!

Grenzwerte für Schweißrauch stehen in der Diskussion. Björn Kemper tritt für die Zählung der Feinstaubpartikel ein.

Are today’s limit values for welding fumes still relevant in their current form? Science and the industrial sector have doubts. KEMPER GmbH argues in favour of measuring the number of particles when evaluating welding fumes concentration. The true health hazard for employees is before the limit is reached – an essay by Björn Kemper.

Resistance welding: Risk from magnetic fields with little welding fumes

Widerstandsschweißen Gefahren magnetische Felder Raumlüftungssystem

Welding fumes are not the greatest risk from resistance welding. Magnetic currents created by the welding process pose a far greater threat to the health of employees.  Use of suction and filtering technology is therefore advisable, at least with a … >> more

WIG welding: “Clean” process with underestimated health risk

It is deemed a “clean” welding process creating only little welding fumes and is therefore often underestimated: WIG welding. The process harbors health risks which should not be underestimated. Welders are exposed to nitrogen oxides, radioactivity and ozone in particular. … >> more

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.

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
