Direct extraction of welding fumes: source capture overview

Punktabsaugung

Source captures are the first choice when it comes to the occupational safety equipment. They are used directly at the place where welding fumes emerge. Three types of source captures are applied for various requirements during welding works. Numerous metal … >> more

“Raising awareness about work safety for welding”

The new information platform on the subject of work safety for welding is called safe-welding.com. In an interview, managing director Björn Kemper explains why KEMPER GmbH, manufacturer of extraction and filter systems, has created the new web site. Work safety … >> more

The optimum exhaust hood for optimum collection

Die Absaughaube entscheidet auch über einen hohen Erfassungsgrad in der Schweißrauchabsaugung.

Extraction systems should making working on pieces easier for welders. A correctly designed exhaust hood helps effectively secure occupational safety. The best extraction performance and the best filter technology are useless if the welding fumes do not find their way … >> more

Differences among filters and how to determine filter class

Filtertechnik mit verschiedenen Abscheideklassen für Filter

The filtration efficiency is classified into one of three welding fume filtration classes. High-grade steel alloys can be safely welded only with the right filter. The welding fume filtration class—the so-called W-classes—let you read the filter performance on the label. … >> more

Ventilation: more than an extension of spot extraction

Eine Raumlüftung ist eine Ergänzung zu Punktabsaugungen.

Whether a displacement or a circulation system: ventilation is more than just a supplement to spot extraction. It also secures the occupational safety for surrounding work areas. For occupational safety during welding, the following actually applies: the thicker the welding … >> more

Health hazard from welding fumes

Beim Schweißrauch wird es vor allem Nanobereich extrem gefährlich für Schweißer.

Contaminants from welding hold a high potential hazard to the health of welders. This is dependent on welding process and material. Welding fumes pose an enormous potential hazard. Official tests show that fume particles are typically smaller than 1 micron, … >> more

Collect and separate: how to achieve effective occupational safety

occupational saftey in welding processes

Extraction and filter technology is fundamental to effective occupational safety. But the behavior of the welder is also significant. Thus collection efficiency is not the same as filtration efficiency. What good does it do occupational safety to use the best … >> more

Contaminant categories: from breathable to ultrafine

Schweißrauch unterteilt sich in einzelne Fraktionen. Besonders gefährlich sind die Partikel ab den alveolengängigen Stäuben.

98.9 percent of welding fumes are harmful to health. Danger lurks in a size under 10 microns for respirable particles. Health risks from welding don’t come only from welding flashes burning the eyes. During welding processes, hazardous substances arise from … >> more

How an effective extraction system works

Schweißrauch absaugen richtet sich auch nach den örtlichen Gegebenheiten.

Extraction and filter technology for an effective occupational safety requires foundational planning. This checklist for welding fume extraction indicates which factors play a role. Plug it in, place the suction arm on the welding seam, and voila, done with occupational … >> more

Extracting welding fumes with right distance from emissions source

There are many more ways to collect welding fumes than often thought. Each has pros and cons, and optimum safety can be achieved – under certain working conditions – only by combining several measures. Burner-integrated spot extraction  In this method, … >> more
