Better welding fumes extraction: Rotatable extraction hood with flange brings higher coverage

Die Absaughaube ist maßgeblich für den Erfassungsgrad des Schweißrauchs.

The quality of an extraction hood is of utmost importance to ensure that welders accept the welding fumes extraction system. Thanks to a special design, the extraction hood with flange requires 40% less repositioning than standard extraction hoods. It is … >> more

Nitrous gases in welding fumes What dangers are faced when welding

nitrous gases in welding processes

Nitrous gases are often responsible for acute poisoning when welding. They occur during gas welding and arc welding processes. Due to current occupational medicine findings, the occupational exposure limits for nitrous gases were significantly lowered in May 2016. The term … >> more

Is welding smoke carcinogenic? International cancer researchers now say a clear ‘yes’!

Welding smoke carcinogenic? International researchers say "yes".

International cancer researchers determined that welding smoke is carcinogenic, in a recently published article. According to the cancer research agency of the World Health Organization, welding smoke has so far only been classified as possibly carcinogenic. With the new classification, the scientists adapted the estimation of the risks posed by welding smoke on the basis of new findings from several studies.

Extraction arm: ten facts for ideal properties when extracting welding fumes

extraction arm for an effektive workplace

An extraction arm must capture welding fumes directly at the point where they arise. Yet welders are not always content with the handling, especially when tracking. In an ideal case, however, an extraction arm helps welders with their work: here are ten facts on how an extraction arm needs to be procured.

40 years of KEMPER – the interview: “In former times, welding fumes were regarded as healthy to some extent”

Kampf dem Schweißrauch seit 40 Jahren: KEMPER ist Pionier in der Schweißrauchabsaugung. Gründer Gerd Kemper blickt im Interview mit arbeitsschutz-schweissen.de zurück.

With a gut feeling, courage and of course a set of reliable figures as a basis, in 1977 Gerd Kemper set out on a personal crusade: clean air at the workplace while welding. Something which in the early days appeared alien to his expectations actually turned out to be a vital business field. 40 years after establishing KEMPER GmbH – formed on 17th March 1977 – Gerd Kemper is now looking back on his company and its industry.

Manganese in welding fumes causes symptoms similar to those of Parkinson’s disease

manganese in welding fumes

Welding with additives containing manganese promotes the occurrence of symptoms that are similar to those of Parkinson’s disease. The higher the manganese content in the welding fumes, the more marked are the symptoms that arise. These are the findings of a recent study.

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.

Regulate extraction technology: for more ease in the battle against welding fumes

When considering extraction and filter technology, manufacturers do not only have to think about the protection of their employees against welding fumes or dust during welding, grinding or cutting. Efficient operation is important for welding workshops when it comes to the plants in addition to consideration on how hazardous substances are captured and discharged. Automatic suction performance regulation also saves energy.

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

MIG welding: highly hazardous despite lower quantities of welding fumes
